152-598: The Tonhalle-Orchester Zürich is a Swiss symphony orchestra based in Zürich . Its principal residence is the Tonhalle concert hall. Precursor music ensembles in Zürich have included the music societies Zum Chorherresaal (around 1600), Ab dem Musiksaal beim Kornhaus (1613), and Zum Fraumünster (1679). In 1812, these ensembles consolidated into a single organization with the name Allgemeine Musik-Gesellschaft (AMG), which included

304-410: A Romantic music repertoire such as the symphonies of Ludwig van Beethoven and Johannes Brahms . The typical orchestra grew in size throughout the 18th and 19th centuries, reaching a peak with the large orchestras of as many as 120 players called for in the works of Richard Wagner and later Gustav Mahler . Orchestras are usually led by a conductor who directs the performance with movements of

456-404: A bridge to a soundboard that amplifies the sound by coupling the acoustic energy to the air. When the key is released, a damper stops the string's vibration, ending the sound. Most notes have three strings, except for the bass, which graduates from one to two. Notes can be sustained when the keys are released by the use of pedals at the base of the instrument, which lift the dampers off

608-561: A grand piano , the frame and strings are horizontal, with the strings extending away from the keyboard. The action lies beneath the strings and uses gravity as its means of return to a state of rest. Grand pianos range in length from approximately 1.5–3 m (4 ft 11 in – 9 ft 10 in). Some of the lengths have been given more-or-less customary names, which vary from time to time and place to place, but might include: All else being equal, longer pianos with longer strings have larger, richer sound and lower inharmonicity of

760-580: A loudspeaker . The electric pianos that became most popular in pop and rock music in the 1960s and 1970s, such as the Fender Rhodes use metal tines in place of strings and use electromagnetic pickups similar to those on an electric guitar . The resulting electrical, analogue signal can then be amplified with a keyboard amplifier or electronically manipulated with effects units . In classical music, electric pianos are mainly used as inexpensive rehearsal or practice instruments. Electric pianos, particularly

912-519: A musical score , which contains all the instrument parts. The conductor uses the score to study the symphony before rehearsals and decide on their interpretation (e.g., tempos, articulation, phrasing, etc.), and to follow the music during rehearsals and concerts, while leading the ensemble. Orchestral musicians play from parts containing just the notated music for their instrument. A small number of symphonies also contain vocal parts (e.g., Beethoven 's Ninth Symphony ). Orchestras also perform overtures ,

1064-410: A pedal keyboard at the base, designed to be played by the feet. The pedals may play the existing bass strings on the piano, or rarely, the pedals may have their own set of bass strings and hammer mechanisms. While the typical intended use for pedal pianos is to enable a keyboardist to practice pipe organ music at home, a few players of pedal piano use it as a performance instrument. Wadia Sabra had

1216-408: A Dutchman, Americus Backers , to design a piano in the harpsichord case—the origin of the "grand". This was achieved by about 1777. They quickly gained a reputation for the splendour and powerful tone of their instruments, with Broadwood constructing pianos that were progressively larger, louder, and more robustly constructed. They sent pianos to both Joseph Haydn and Ludwig van Beethoven , and were

1368-414: A built-in amp and speaker). Alternatively, a person can play an electronic piano with headphones in quieter settings. Digital pianos are also non-acoustic and do not have strings or hammers. They use digital audio sampling technology to reproduce the acoustic sound of each piano note accurately. They also must be connected to a power amplifier and speaker to produce sound (however, most digital pianos have

1520-437: A built-in amp and speaker). Alternatively, a person can practise with headphones to avoid disturbing others. Digital pianos can include sustain pedals, weighted or semi-weighted keys, multiple voice options (e.g., sampled or synthesized imitations of electric piano, Hammond organ , violin , etc.), and MIDI interfaces. MIDI inputs and outputs connect a digital piano to other electronic instruments or musical devices. For example,

1672-413: A conductor, although early orchestras did not have one, giving this role to the concertmaster or the harpsichordist playing the continuo . Some modern orchestras also do without conductors , particularly smaller orchestras and those specializing in historically accurate (so-called "period") performances of baroque and earlier music. The most frequently performed repertoire for a symphony orchestra

1824-514: A consensus that faking may be acceptable when a part is not written well for the instrument, but faking "just because you haven't practised" the music is not acceptable. With the advent of the early music movement, smaller orchestras where players worked on execution of works in styles derived from the study of older treatises on playing became common. These include the Orchestra of the Age of Enlightenment ,

1976-475: A digital piano's MIDI out signal could be connected by a patch cord to a synth module , which would allow the performer to use the keyboard of the digital piano to play modern synthesizer sounds. Early digital pianos tended to lack a full set of pedals, but the synthesis software of later models such as the Yamaha Clavinova series synthesised the sympathetic vibration of the other strings (such as when

2128-622: A few decades of use. Beginning in 1961, the New York branch of the Steinway firm incorporated Teflon , a synthetic material developed by DuPont , for some parts of its Permafree grand action in place of cloth bushings, but abandoned the experiment in 1982 due to excessive friction and a "clicking" that developed over time; Teflon is "humidity stable" whereas the wood adjacent to the Teflon swells and shrinks with humidity changes, causing problems. More recently,

2280-613: A form of piano wire made from cast steel ; it was "so superior to the iron wire that the English firm soon had a monopoly." A better steel wire was developed in 1840 by the Viennese firm Martin Miller, and a period of innovation and intense competition ensued, with rival brands of piano wire being tested against one another at international competitions, leading ultimately to the modern form of piano wire. Several important advances included changes to

2432-522: A given performance may vary from seventy to over one hundred, depending on the work being played and the venue size. A chamber orchestra (sometimes a concert orchestra ) is a smaller ensemble of not more than about fifty musicians. Orchestras that specialize in the Baroque music of, for example, Johann Sebastian Bach and George Frideric Handel , or Classical repertoire, such as that of Haydn and Mozart , tend to be smaller than orchestras performing

2584-525: A harmonic produced from three octaves below. This lets close and widespread octaves sound pure, and produces virtually beatless perfect fifths . This gives the concert grand a brilliant, singing and sustaining tone quality—one of the principal reasons that full-size grands are used in the concert hall. Smaller grands satisfy the space and cost needs of domestic use; as well, they are used in some small teaching studios and smaller performance venues. Upright pianos, also called vertical pianos, are more compact with

2736-553: A hundred, but the actual number of musicians employed in a particular performance may vary according to the work being played and the size of the venue. A chamber orchestra is usually a smaller ensemble; a major chamber orchestra might employ as many as fifty musicians, but some are much smaller. Concert orchestra is an alternative term, as in the BBC Concert Orchestra and the RTÉ Concert Orchestra . Apart from

2888-415: A live performance, could be heard by critics. As recording technologies improved over the 20th and 21st centuries, eventually small errors in a recording could be "fixed" by audio editing or overdubbing . Some older conductors and composers could remember a time when simply "getting through" the music as well as possible was the standard. Combined with the wider audience made possible by recording, this led to

3040-478: A lower octave's corresponding sharp overtone rather than to a theoretically correct octave. If octaves are not stretched, single octaves sound in tune, but double—and notably triple—octaves are unacceptably narrow. Stretching a small piano's octaves to match its inherent inharmonicity level creates an imbalance among all the instrument's intervallic relationships. In a concert grand, however, the octave "stretch" retains harmonic balance, even when aligning treble notes to

3192-609: A massive, strong, cast iron frame. Also called the "plate", the iron frame sits atop the soundboard , and serves as the primary bulwark against the force of string tension that can exceed 20 tons (180 kilonewtons) in total for a modern grand piano. The single piece cast iron frame for square piano was patented in 1825 in Boston by Alpheus Babcock , combining the metal hitch pin plate (1821, claimed by Broadwood on behalf of Samuel Hervé) and resisting bars (Thom and Allen, 1820, but also claimed by Broadwood and Érard). Babcock later worked for

With technological advances , amplified electric pianos (1929), electronic pianos (1970s), and digital pianos (1980s) have been developed. The first electric pianos from the late 1920s used metal strings with a magnetic pickup , an amplifier and

3496-846: A modified member of the horn family, appears in Richard Wagner 's cycle Der Ring des Nibelungen and several other works by Strauss, Igor Stravinsky (as featured in The Rite of Spring ), Béla Bartók , and others; it also has a notably prominent role in Anton Bruckner 's Symphony No. 7 in E ;Major . Cornets appear in Pyotr Ilyich Tchaikovsky 's ballet Swan Lake , Claude Debussy 's La Mer , and several orchestral works by Hector Berlioz . Unless these instruments are played by members "doubling" on another instrument (for example,

3648-400: A musical device exploited by Liszt. When the invention became public, as revised by Henri Herz , the double escapement action gradually became standard in grand pianos and is still incorporated into all grand pianos currently produced in the 2000s. Other improvements of the mechanism included the use of firm felt hammer coverings instead of layered leather or cotton. Felt, which Jean-Henri Pape

3800-522: A particular city or region. The term orchestra derives from the Greek ὀρχήστρα ( orchestra ), the name for the area in front of a stage in ancient Greek theatre reserved for the Greek chorus . In the Baroque era, the size and composition of an orchestra were not standardised. There were large differences in size, instrumentation and playing styles—and therefore in orchestral soundscapes and palettes — between

3952-624: A permanent member who is sick. A professional musician who is hired to perform for a single concert is sometimes called a "sub". Some contract musicians may be hired to replace permanent members for the period that the permanent member is on parental leave or disability leave. Historically, major professional orchestras have been mostly or entirely composed of men. The first women members hired in professional orchestras have been harpists . The Vienna Philharmonic , for example, did not accept women to permanent membership until 1997, far later than comparable orchestras (the other orchestras ranked among

4104-441: A piano are made of a steel core wrapped with one or two layers of copper wire, to increase their mass whilst retaining flexibility. If all strings throughout the piano's compass were individual (monochord), the massive bass strings would overpower the upper ranges. Makers compensate for this with the use of double (bichord) strings in the tenor and triple (trichord) strings throughout the treble. The plate (harp), or metal frame, of

4256-439: A piano are made of materials selected for strength and longevity. This is especially true of the outer rim, which is most commonly made of hardwood , typically hard maple or beech , and its massiveness serves as an essentially immobile object from which the flexible soundboard can best vibrate. According to Harold A. Conklin, the purpose of a sturdy rim is so that, "... the vibrational energy will stay as much as possible in

4408-468: A piano can be played acoustically, or the keyboard can be used as a MIDI controller, which can trigger a synthesizer module or music sampler . Some electronic feature-equipped pianos such as the Yamaha Disklavier electronic player piano, introduced in 1987, are outfitted with electronic sensors for recording and electromechanical solenoids for player piano-style playback. Sensors record the movements of

4560-419: A piano is usually made of cast iron. A massive plate is advantageous. Since the strings vibrate from the plate at both ends, an insufficiently massive plate would absorb too much of the vibrational energy that should go through the bridge to the soundboard. While some manufacturers use cast steel in their plates, most prefer cast iron. Cast iron is easy to cast and machine, has flexibility sufficient for piano use,

4712-467: A piano. An inventory made by his employers, the Medici family, indicates the existence of a piano by 1700. The three Cristofori pianos that survive today date from the 1720s. Cristofori named the instrument un cimbalo di cipresso di piano e forte ("a keyboard of cypress with soft and loud"), abbreviated over time as pianoforte , fortepiano , and later reduced to only piano . Cristofori's great success

4864-434: A position in which it is ready to play again almost immediately after its key is depressed, so the player can repeat the same note rapidly when desired. Cristofori's piano action was a model for the many approaches to piano actions that followed in the next century. Cristofori's early instruments were made with thin strings and were much quieter than the modern piano, though they were louder and had more sustain compared to

5016-405: A range of different employment arrangements. The most sought-after positions are permanent, tenured positions in the orchestra. Orchestras also hire musicians on contracts, ranging in length from a single concert to a full season or more. Contract performers may be hired for individual concerts when the orchestra is doing an exceptionally large late-Romantic era orchestral work, or to substitute for

5168-412: A renewed focus on particular star conductors and on a high standard of orchestral execution. The typical symphony orchestra consists of four groups of related musical instruments called the woodwinds , brass , percussion , and strings . Other instruments such as the piano, accordion , and celesta may sometimes be grouped into a fifth section such as a keyboard section or may stand alone, as may

5320-596: A small number of acoustic pianos in the 2010s are produced with MIDI recording and digital sound module -triggering capabilities, the 19th century was the era of the most dramatic innovations and modifications of the instrument. Modern pianos have two basic configurations, the grand piano and the upright piano, with various styles of each. There are also specialized and novelty pianos, electric pianos based on electromechanical designs, electronic pianos that synthesize piano-like tones using oscillators, and digital pianos using digital samples of acoustic piano sounds. In

5472-437: A term originally applied to the instrumental introduction to an opera. During the early Romantic era, composers such as Beethoven and Mendelssohn began to use the term to refer to independent, self-existing instrumental, programmatic works that presaged genres such as the symphonic poem , a form devised by Franz Liszt in several works that began as dramatic overtures. These were "at first undoubtedly intended to be played at

5624-458: A trend toward donors finding other social causes more compelling. While government funding is less central to American than European orchestras, cuts in such funding are still significant for American ensembles. Finally, the drastic drop in revenues from recording, related to changes in the recording industry itself, began a period of change that has yet to reach its conclusion. U.S. orchestras that have gone into Chapter 11 bankruptcy include

5776-461: A trombone player changing to euphonium or a bassoon player switching to contrabassoon for a certain passage), orchestras typically hire freelance musicians to augment their regular ensemble. The 20th century orchestra was far more flexible than its predecessors. In Beethoven's and Felix Mendelssohn 's time, the orchestra was composed of a fairly standard core of instruments, which was very rarely modified by composers. As time progressed, and as

5928-490: A variety of amateur orchestras: Orchestras play a wide range of repertoire ranging from 17th-century dance suites , 18th century divertimentos to 20th-century film scores and 21st-century symphonies. Orchestras have become synonymous with the symphony , an extended musical composition in Western classical music that typically contains multiple movements which provide contrasting keys and tempos. Symphonies are notated in

6080-656: A vertical structure of the frame and strings. The mechanical action structure of the upright piano was invented in London in 1826 by Robert Wornum, and upright models became the most popular model for domestic use. Upright pianos take up less space than a grand piano and as such are a better size for use in private homes for domestic music-making and practice. The hammers move horizontally and return to their resting position via springs, which are susceptible to degradation. Upright pianos with unusually tall frames and long strings were sometimes marketed as upright grand pianos, but that label

6232-436: A wide range of repertoire, including symphonies, opera and ballet overtures , concertos for solo instruments, and pit ensembles for operas, ballets, and some types of musical theatre (e.g., Gilbert and Sullivan operettas ). Amateur orchestras include youth orchestras made up of students from an elementary school, a high school, or a university, and community orchestras; typically they are made up of amateur musicians from

However, orchestras are used sometimes in popular music (e.g., to accompany a rock or pop band in a concert), extensively in film music , and increasingly often in video game music . Orchestras are also used in the symphonic metal genre. The term "orchestra" can also be applied to a jazz ensemble, for example in the performance of big-band music. In

6536-417: Is called for in a string section, the section leader invariably plays that part. The section leader (or principal) of a string section is also responsible for determining the bowings, often based on the bowings set out by the concertmaster. In some cases, the principal of a string section may use a slightly different bowing than the concertmaster, to accommodate the requirements of playing their instrument (e.g.,

6688-465: Is misleading. Some authors classify modern pianos according to their height and to modifications of the action that are necessary to accommodate the height. Upright pianos are generally less expensive than grand pianos. Upright pianos are widely used in churches, community centers, schools, music conservatories and university music programs as rehearsal and practice instruments, and they are popular models for in-home purchase. The toy piano , introduced in

6840-580: Is much more resistant to deformation than steel, and is especially tolerant of compression. Plate casting is an art, since dimensions are crucial and the iron shrinks about one percent during cooling. Including an extremely large piece of metal in a piano is potentially an aesthetic handicap. Piano makers overcome this by polishing, painting, and decorating the plate. Plates often include the manufacturer's ornamental medallion. In an effort to make pianos lighter, Alcoa worked with Winter and Company piano manufacturers to make pianos using an aluminum plate during

6992-588: The "Eroica" Symphony arrives to provide not only some harmonic flexibility but also the effect of "choral" brass in the Trio movement. Piccolo , contrabassoon , and trombones add to the triumphal finale of his Symphony No. 5 . A piccolo and a pair of trombones help deliver the effect of storm and sunshine in the Sixth , also known as the Pastoral Symphony . The Ninth asks for a second pair of horns, for reasons similar to

7144-578: The Chickering & Mackays firm who patented the first full iron frame for grand pianos in 1843. Composite forged metal frames were preferred by many European makers until the American system was fully adopted by the early 20th century. The increased structural integrity of the iron frame allowed the use of thicker, tenser, and more numerous strings. In 1834, the Webster & Horsfal firm of Birmingham brought out

7296-449: The Kawai firm built pianos with action parts made of more modern materials such as carbon fiber reinforced plastic , and the piano parts manufacturer Wessell, Nickel and Gross has launched a new line of carefully engineered composite parts. Thus far these parts have performed reasonably, but it will take decades to know if they equal the longevity of wood. In all but the lowest quality pianos,

In the United States, the late 20th century saw a crisis of funding and support for orchestras. The size and cost of a symphony orchestra, compared to the size of the base of supporters, became an issue that struck at the core of the institution. Few orchestras could fill auditoriums, and

The Festival of Orchestras in Orlando, Florida, ceased operations at

7752-780: The Steinway concert grand (Model D) weighs 480 kg (1,060 lb). The largest piano available on the general market, the Fazioli F308, weighs 570 kg (1,260 lb). The pinblock, which holds the tuning pins in place, is another area where toughness is important. It is made of hardwood (typically hard maple or beech) and is laminated for strength, stability and longevity. Piano strings (also called piano wire ), which must endure years of extreme tension and hard blows, are made of high carbon steel. They are manufactured to vary as little as possible in diameter, since all deviations from uniformity introduce tonal distortion. The bass strings of

8056-440: The concert harp and electric and electronic instruments. The orchestra, depending on the size, contains almost all of the standard instruments in each group. In the history of the orchestra, its instrumentation has been expanded over time, often agreed to have been standardized by the classical period and Ludwig van Beethoven 's influence on the classical model. In the 20th and 21st century, new repertory demands expanded

8208-462: The grand piano and the upright piano . The grand piano offers better sound and more precise key control, making it the preferred choice when space and budget allow. The grand piano is also considered a necessity in venues hosting skilled pianists. The upright piano is more commonly used because of its smaller size and lower cost. When a key is depressed, the strings inside are struck by felt-coated wooden hammers. The vibrations are transmitted through

8360-600: The hammered dulcimers , which were introduced in the Middle Ages in Europe. During the Middle Ages, there were several attempts at creating stringed keyboard instruments with struck strings. By the 17th century, the mechanisms of keyboard instruments such as the clavichord and the harpsichord were well developed. In a clavichord the strings are struck by tangents, while in a harpsichord they are mechanically plucked by quills when

8512-464: The piano , harpsichord , pipe organ , and celesta may sometimes appear in a fifth keyboard section or may stand alone as soloist instruments, as may the concert harp and, for performances of some modern compositions, electronic instruments , and guitars . A full-size Western orchestra may sometimes be called a symphony orchestra or philharmonic orchestra (from Greek phil- , "loving", and "harmony"). The number of musicians employed in

8664-537: The transposing piano in 1801. This rare instrument has a lever under the keyboard to move the keyboard relative to the strings, so a pianist can play in a familiar key while the music sounds in a different key. The minipiano is an instrument patented by the Brasted brothers of the Eavestaff Ltd. piano company in 1934. This instrument has a braceless back and a soundboard positioned below the keys—long metal rods pull on

In 1821, Sébastien Érard invented the double escapement action, which incorporated a repetition lever (also called the balancier ) that permitted repeating a note even if the key had not return to its resting position. This facilitated rapid playing of repeated notes,

The numerous parts of a piano action are generally made from hardwood, such as maple, beech, or hornbeam ; however, since World War II, makers have also incorporated plastics. Early plastics used in some pianos in the late 1940s and 1950s, proved problematic when they lost strength after

9576-606: The 19th century is generally attributed to the forces called for by Beethoven after Haydn and Mozart. Beethoven's instrumentation almost always included paired flutes , oboes, clarinets, bassoons, horns and trumpets. The exceptions are his Symphony No. 4 , Violin Concerto , and Piano Concerto No. 4 , which each specify a single flute. Beethoven carefully calculated the expansion of this particular timbral "palette" in Symphonies 3, 5, 6, and 9 for an innovative effect. The third horn in

Performers typically play one or more solo pieces of the auditionee's choice, such as a movement of a concerto, a solo Bach movement, and a variety of excerpts from the orchestral literature that are advertised in the audition poster (so the auditionees can prepare). The excerpts are typically

The orchestra and Andreae made a small number of recordings in the late 1920s, of music of Vivaldi and Wolfgang Amadeus Mozart. In 1947, Franz Lehár recorded a number of 78-rpm discs of his music with the orchestra for Decca Records . The discs were issued in

10184-675: The Classical era, as composers increasingly sought out financial support from the general public, orchestra concerts were increasingly held in public concert halls , where music lovers could buy tickets to hear the orchestra. Aristocratic patronage of orchestras continued during the Classical era, but this went on alongside public concerts. In the 20th and 21st century, orchestras found a new patron: governments. Many orchestras in North America and Europe receive part of their funding from national, regional level governments (e.g., state governments in

Electronic pianos are non-acoustic; they do not have strings, tines or hammers, but are a type of analog synthesizer that simulates or imitates piano sounds using oscillators and filters that synthesize the sound of an acoustic piano. They must be connected to a keyboard amplifier and speaker to produce sound (however, some electronic keyboards have

10488-517: The Romantic period saw changes in accepted modification with composers such as Berlioz and Mahler; some composers used multiple harps and sound effect such as the wind machine . During the 20th century, the modern orchestra was generally standardized with the modern instrumentation listed below. Nevertheless, by the mid- to late 20th century, with the development of contemporary classical music , instrumentation could practically be hand-picked by

10640-526: The Tonhalle-Orchester was Friedrich Hegar , who served from its founding in 1868 through 1906. His successor, Volkmar Andreae , served an even longer tenure as chief conductor, from 1906 to 1949, the longest in the orchestra's history, directing around 1,300 concerts with the orchestra. Andreae's tenure featured the first family concerts by the orchestra, beginning in 1928. In 1947, the city of Zürich formalised performances of concerts for young people by

10792-420: The U.S. by London Records , initially in the 78-rpm format and then on LPs. Some of the recordings are now available through Naxos Records on CD. The orchestra's recording profile has expanded most prominently during the tenure of Zinman, with many recordings for such labels as Arte Nova and RCA. In particular, his recordings for Arte Nova of the complete Beethoven symphonies achieved notable renown, as one of

10944-472: The U.S.) or city governments. These government subsidies make up part of orchestra revenue, along with ticket sales, charitable donations (if the orchestra is registered as a charity) and other fundraising activities. With the invention of successive technologies, including sound recording , radio broadcasting , television broadcasting and Internet-based streaming and downloading of concert videos, orchestras have been able to find new revenue sources. One of

11096-763: The VPO now uses completely screened blind auditions . In 2013, an article in Mother Jones stated that while "[m]any prestigious orchestras have significant female membership — women outnumber men in the New York Philharmonic 's violin section — and several renowned ensembles, including the National Symphony Orchestra , the Detroit Symphony , and the Minnesota Symphony, are led by women violinists",

Cristofori's new instrument remained relatively unknown until an Italian writer, Scipione Maffei , wrote an enthusiastic article about it in 1711, including a diagram of the mechanism, that was translated into German and widely distributed. Most of

A section string player plays in unison with the rest of the section, except in the case of divided ( divisi ) parts, where upper and lower parts in the music are often assigned to "outside" (nearer the audience) and "inside" seated players. Where a solo part

11552-414: The century, as the piano became more common it allowed families to listen to a newly published musical piece by having a family member play a simplified version . The piano is widely employed in classical , jazz , traditional and popular music for solo and ensemble performances, accompaniment, and for composing , songwriting and rehearsals. Despite its weight and cost, the piano's versatility,

11704-416: The classical era, the orchestra became more standardized with a small to medium-sized string section and a core wind section consisting of pairs of oboes, flutes, bassoons and horns, sometimes supplemented by percussion and pairs of clarinets and trumpets. The so-called "standard complement" of doubled winds and brass in the orchestra pioneered in the late 18th century and consolidated during the first half of

11856-511: The clavichord—the only previous keyboard instrument capable of dynamic nuance responding to the player's touch, the velocity with which the keys are pressed. While the clavichord allows expressive control of volume and sustain, it is relatively quiet even at its loudest. The harpsichord produces a sufficiently loud sound, especially when a coupler joins each key to both manuals of a two-manual harpsichord, but it offers no dynamic or expressive control over individual notes. The piano in some sense offers

12008-498: The common complement of a 2010-era modern orchestra (e.g., Adams , Barber , Aaron Copland , Glass , Penderecki ). Among the instrument groups and within each group of instruments, there is a generally accepted hierarchy. Every instrumental group (or section) has a principal who is generally responsible for leading the group and playing orchestral solos. The violins are divided into two groups, first violin and second violin, with

12160-406: The composer (e.g., to add electric instruments such as electric guitar, electronic instruments such as synthesizers, ondes martenot , or trautonium , as well as other non-Western instruments, or other instruments not traditionally used in orchestras including the: bandoneon , free bass accordion , harmonica , jews harp , mandola and water percussion. With this history in mind,

12312-413: The conductor and the panel to compare the best candidates. Performers may be asked to sight read orchestral music. The final stage of the audition process in some orchestras is a test week , in which the performer plays with the orchestra for a week or two, which allows the conductor and principal players to see if the individual can function well in an actual rehearsal and performance setting. There are

12464-662: The conductor of the theatre orchestra, as he elaborated in his influential work On Conducting . This brought about a revolution in orchestral composition and set the style for orchestral performance for the next eighty years. Wagner's theories re-examined the importance of tempo , dynamics , bowing of string instruments and the role of principals in the orchestra. At the beginning of the 20th century, symphony orchestras were larger, better funded, and better trained than previously; consequently, composers could compose larger and more ambitious works. The works of Gustav Mahler were particularly innovative; in his later symphonies, such as

12616-443: The core orchestral complement, various other instruments are called for occasionally. These include the flugelhorn and cornet . Saxophones and classical guitars, for example, appear in some 19th- through 21st-century scores. While appearing only as featured solo instruments in some works, for example Maurice Ravel 's orchestration of Modest Mussorgsky 's Pictures at an Exhibition and Sergei Rachmaninoff 's Symphonic Dances ,

12768-436: The double bass, brass, and percussion sections of major orchestras "... are still predominantly male." A 2014 BBC article stated that the "... introduction of 'blind' auditions, where a prospective instrumentalist performs behind a screen so that the judging panel can exercise no gender or racial prejudice, has seen the gender balance of traditionally male-dominated symphony orchestras gradually shift." There are also

12920-400: The double-bass section). Principals of a string section will also lead entrances for their section, typically by lifting the bow before the entrance, to ensure the section plays together. Tutti wind and brass players generally play a unique but non-solo part. Section percussionists play parts assigned to them by the principal percussionist. In modern times, the musicians are usually directed by

13072-441: The earliest recorded cycles to use the new Jonathan Del Mar edition of the symphonies, with observation of Beethoven's metronome markings. Symphony orchestra An orchestra ( / ˈ ɔːr k ɪ s t r ə / ; OR -ki-strə ) is a large instrumental ensemble typical of classical music, which combines instruments from different families. There are typically four main sections of instruments: Other instruments such as

13224-406: The end of March 2011. Piano A piano is a keyboard instrument that produces sound when its keys are depressed, activating an action mechanism where hammers strike strings . Modern pianos have a row of 88 black and white keys, tuned to a chromatic scale in equal temperament . A musician who specializes in piano is called a pianist . There are two main types of piano:

13376-563: The end of his current contract, at the end of the 2017–2018 season. In May 2017, the orchestra announced the appointment of Paavo Järvi as its next chief conductor, effective with the 2019–2020 season, with an initial contract of five years. Järvi had first guest-conducted the Tonhalle Orchestra in 2009, and returned in December 2016. In December 2022, the orchestra announced an extension of Järvi's contract as its chief conductor through

13528-481: The extensive training of musicians, and its availability in venues, schools, and rehearsal spaces have made it a familiar instrument in the Western world. The piano was based on earlier technological innovations in keyboard instruments . Pipe organs had been used since antiquity, and as such the development of pipe organs enabled instrument builders to learn about creating keyboard mechanisms for sounding pitches . The first string instruments with struck strings were

13680-418: The first firm to build pianos with a range of more than five octaves: five octaves and a fifth during the 1790s, six octaves by 1810 (Beethoven used the extra notes in his later works), and seven octaves by 1820. The Viennese makers similarly followed these trends; however the two schools used different piano actions: Broadwoods used a more robust action, whereas Viennese instruments were more sensitive. By

13832-434: The first systematic treatise on using instrumental sound as an expressive element of music. The next major expansion of symphonic practice came from Richard Wagner 's Bayreuth orchestra, founded to accompany his musical dramas. Wagner's works for the stage were scored with unprecedented scope and complexity: indeed, his score to Das Rheingold calls for six harps . Thus, Wagner envisioned an ever-more-demanding role for

13984-416: The first violin section – commonly called the concertmaster – also plays an important role in leading the musicians. In the Baroque music era (1600–1750), orchestras were often led by the concertmaster, or by a chord-playing musician performing the basso continuo parts on a harpsichord or pipe organ , a tradition that some 20th-century and 21st-century early music ensembles continue. Orchestras play

14136-507: The floor, behind the keyboard and very large sticker action . The short cottage upright or pianino with vertical stringing—made popular by Robert Wornum around 1815—was built into the 20th century. They are informally called birdcage pianos because of their prominent damper mechanism. The oblique upright, popularized in France by Roller & Blanchet during the late 1820s, was diagonally strung throughout its compass. The tiny spinet upright

14288-540: The form of upright, baby grand, and grand piano styles (including a nine-foot concert grand). Reproducing systems have ranged from relatively simple, playback-only models to professional models that can record performance data at resolutions that exceed the limits of normal MIDI data. The unit mounted under the keyboard of the piano can play MIDI or audio software on its CD. Pianos can have over 12,000 individual parts, supporting six functional features: keyboard, hammers, dampers, bridge, soundboard, and strings. Many parts of

14440-546: The formation of an orchestra who performed on an annual, seasonal and non-permanent basis. In the early history of the AMG orchestra, its first principal conductors were Casimir von Blumenthal (1821–1846) and Franz Abt (1846–1852). The impetus for the establishment of a permanent orchestra in Zürich came in 1861, with the Schweizerische Musikfest (Swiss Music Festival) scheduled in Zürich that year. Citizens in Zürich wished

14592-448: The framework to resonate more freely with the soundboard, creating additional coloration and complexity of the overall sound. The thick wooden posts on the underside (grands) or back (uprights) of the piano stabilize the rim structure and are made of softwood for stability. The requirement of structural strength, fulfilled by stout hardwood and thick metal, makes a piano heavy. Even a small upright can weigh 136 kg (300 lb), and

14744-577: The full range of orchestral sounds and timbres during the performance of orthodox Western classical music. The terms symphony orchestra and philharmonic orchestra may be used to distinguish different ensembles from the same locality, such as the London Symphony Orchestra and the London Philharmonic Orchestra . A symphony or philharmonic orchestra will usually have over eighty musicians on its roster, in some cases over

14896-439: The hands and arms, often made easier for the musicians to see by using a short wooden rod known as a conductor's baton . The conductor unifies the orchestra, sets the tempo , and shapes the sound of the ensemble. The conductor also prepares the orchestra by leading rehearsals before the public concert, in which the conductor provides instructions to the musicians on their interpretation of the music being performed. The leader of

15048-543: The head of a programme". In the 1850s the concert overture began to be supplanted by the symphonic poem. Orchestras also play with instrumental soloists in concertos. During concertos, the orchestra plays an accompaniment role to the soloist (e.g., a solo violinist or pianist) and, at times, introduces musical themes or interludes while the soloist is not playing. Orchestras also play during operas, ballets, some musical theatre works and some choral works (both sacred works such as Masses and secular works). In operas and ballets,

15200-415: The higher notes were too soft to allow a full dynamic range. Although this earned him some animosity from Silbermann, the criticism was apparently heeded. Bach did approve of a later instrument he saw in 1747 and even served as an agent in selling Silbermann's pianos. "Instrument: piano et forte genandt"—a reference to the instrument's ability to play soft and loud—was an expression that Bach used to help sell

15352-542: The instrument when he was acting as Silbermann's agent in 1749. Piano making flourished during the late 18th century in the Viennese school , which included Johann Andreas Stein (who worked in Augsburg , Germany) and the Viennese makers Nannette Streicher (daughter of Stein) and Anton Walter . Viennese-style pianos were built with wood frames, two strings per note, and leather-covered hammers. Some of these Viennese pianos had

15504-553: The instrumentation of the orchestra, resulting in a flexible use of the classical-model instruments and newly developed electric and electronic instruments in various combinations. In the mid 20th century, several attempts were made in Germany and the United States to confine the instrumentation of the symphonic orchestra exclusively to groups of one instrument. In this configuration, the symphonic orchestra consisted entirely of free-reed chromatic accordions which were modified to recreate

15656-472: The keyboard set along the long side. This design is attributed to Christian Ernst Friderici (a pupil of Gottfried Silbermann) in Germany and Johannes Zumpe in England, and it was improved by changes first introduced by Guillaume-Lebrecht Petzold in France and Alpheus Babcock in the United States. Square pianos were built in great numbers through the 1840s in Europe and the 1890s in the United States, and saw

15808-605: The keys, hammers, and pedals during a performance, and the system saves the performance data as a Standard MIDI File (SMF). On playback, the solenoids move the keys and pedals and thus reproduce the original performance. Modern Disklaviers typically include an array of electronic features, such as a built-in tone generator for playing back MIDI accompaniment tracks, speakers, MIDI connectivity that supports communication with computing devices and external MIDI instruments, additional ports for audio and SMPTE input/output (I/O), and Internet connectivity. Disklaviers have been manufactured in

15960-505: The levers to make the hammers strike the strings. The first model, known as the Pianette , was unique in that the tuning pins extended through the instrument, so it could be tuned at the front. The prepared piano , present in some contemporary art music from the 20th and 21st century is a piano which has objects placed inside it to alter its sound, or has had its mechanism changed in some other way. The scores for music for prepared piano specify

16112-526: The mammoth Symphony No. 8 , Mahler pushes the furthest boundaries of orchestral size, employing large forces. By the late Romantic era, orchestras could support the most enormous forms of symphonic expression, with huge string and brass sections and an expanded range of percussion instruments. With the recording era beginning, the standards of performance were pushed to a new level, because a recorded symphony could be listened to closely and even minor errors in intonation or ensemble, which might not be noticeable in

16264-408: The modifications, for example, instructing the pianist to insert pieces of rubber, paper, metal screws, or washers in between the strings. These objects mute the strings or alter their timbre. Some Viennese fortepianos incorporated percussion effects, brought into action by levers. These would be used in pieces such as Mozart's Rondo alla Turca . The pedal piano is a rare type of piano that has

16416-445: The most technically challenging parts and solos from the orchestral literature. Orchestral auditions are typically held in front of a panel that includes the conductor, the concertmaster , the principal player of the section for which the auditionee is applying, and possibly other principal players. The most promising candidates from the first round of auditions are invited to return for a second or third round of auditions, which allows

16568-500: The most visible change of any type of piano: the iron-framed, over-strung squares manufactured by Steinway & Sons were more than two-and-a-half times the size of Zumpe's wood-framed instruments from a century before. Their overwhelming popularity was the result of inexpensive construction and price, although their tone and performance were limited by narrow soundboards, simple actions and string spacing that made proper hammer alignment difficult. The tall, vertically strung upright grand

16720-557: The musicians to remain after the festival, but the AMG did not have the financial resources to establish a permanent resident orchestra. Subsequently, a group of Zürich citizens founded the Orchesterverein in 1865 as the city's first permanent orchestra. The founding of the Tonhalle-Orchester Zürich followed several years later, in 1868. Both ensembles continue to perform in Zürich today. The first principal conductor of

16872-410: The next generation of piano builders started their work based on reading this article. One of these builders was Gottfried Silbermann , better known as an organ builder. Silbermann's pianos were virtual copies of Cristofori's, with one important addition: Silbermann invented the forerunner of the modern sustain pedal , which lifts all the dampers from the strings simultaneously. This innovation allows

17024-545: The opposite coloring of modern-day pianos; the natural keys were black and the accidental keys white. It was for such instruments that Wolfgang Amadeus Mozart composed his concertos and sonatas , and replicas of them are built in the 21st century for use in authentic-instrument performance of his music. The pianos of Mozart's day had a softer tone than 21st century pianos or English pianos, with less sustaining power. The term fortepiano now distinguishes these early instruments (and modern re-creations) from later pianos. In

17176-436: The orchestra accompanies the singers and dancers, respectively, and plays overtures and interludes where the melodies played by the orchestra take centre stage. In the Baroque era, orchestras performed in a range of venues, including at the fine houses of aristocrats, in opera halls and in churches. Some wealthy aristocrats had an orchestra in residence at their estate, to entertain them and their guests with performances. During

17328-509: The orchestra can be analysed in five eras: the Baroque era , the Classical era , early/mid- Romantic music era, late-Romantic era and combined Modern/Postmodern eras . The first is a Baroque orchestra (i.e., J.S. Bach , Handel , Vivaldi ), which generally had a smaller number of performers, and in which one or more chord-playing instruments, the basso continuo group (e.g., harpsichord or pipe organ and assorted bass instruments to perform

17480-464: The orchestra gathered [on 28 February 1997] in an extraordinary meeting on the eve of their departure and agreed to admit a woman, Anna Lelkes, as harpist." As of 2013, the orchestra has six female members; one of them, violinist Albena Danailova, became one of the orchestra's concertmasters in 2008, the first woman to hold that position in that orchestra. In 2012, women made up 6% of the orchestra's membership. VPO president Clemens Hellsberg said

17632-413: The orchestra named Lionel Bringuier as its next chief conductor, as of the 2014–2015 season, with an initial contract of four years. Concurrent with the advent of Bringuier as chief conductor in the 2014–2015 season, Esa-Pekka Salonen began his tenure in the newly created post of Creative Chair of the orchestra. In August 2016, the orchestra announced that Bringuier is to conclude his Tonhalle tenure at

17784-644: The orchestra's press secretary wrote that "compensating for the expected leaves of absence" of maternity leave would be a problem. In 1997, the Vienna Philharmonic was "facing protests during a [US] tour" by the National Organization for Women and the International Alliance for Women in Music . Finally, "after being held up to increasing ridicule even in socially conservative Austria, members of

17936-551: The orchestra, as part of the agreements for city funding and subsidy of the orchestra. More recently, during the chief conductorship of David Zinman , the orchestra established its "tonhalleLATE" series of late-evening concerts that combine shorter-length symphonic concerts with socializing afterwards to electronic music. In the interregnum between the chief conductorships of Hiroshi Wakasugi and David Zinman , Claus Peter Flor served as principal guest conductor from 1991 to 1995. Zinman became chief conductor in 1995, and remained in

18088-543: The performer depresses the key. Centuries of work on the mechanism of the harpsichord in particular had shown instrument builders the most effective ways to construct the case, soundboard, bridge, and mechanical action for a keyboard intended to sound strings. The English word piano is a shortened form of the Italian pianoforte , derived from gravecembalo col piano e forte ("harpsichord with soft and loud"). Variations in volume ( loudness ) are produced in response to

18240-462: The period from about 1790 to 1860, the Mozart-era piano underwent significant changes that led to the modern structure of the instrument. This revolution was in response to a preference by composers and pianists for a more powerful, sustained piano sound, which was made possible by the ongoing Industrial Revolution with resources such as high-quality piano wire for strings and precision casting for

18392-437: The pianist to sustain the notes that they have depressed even after their fingers are no longer pressing down the keys. As such, by holding a chord with the sustain pedal, pianists can relocate their hands to a different register of the keyboard in preparation for a subsequent section. Silbermann showed Johann Sebastian Bach one of his early instruments in the 1730s, but Bach did not like the instrument at that time, saying that

18544-439: The pianist's touch (pressure on the keys): the greater the pressure, the greater the force of the hammer hitting the strings and the louder the sound produced and the stronger the attack . Invented in 1700, the fortepiano was the first keyboard instrument to allow gradations of volume and tone according to how forcefully or softly the player presses or strikes the keys, unlike the pipe organ and harpsichord. The invention of

18696-537: The piano is credited to Bartolomeo Cristofori of Padua , Italy, who was employed by Ferdinando de' Medici, Grand Prince of Tuscany , as the Keeper of the Instruments. Cristofori was an expert harpsichord maker and was well acquainted with the body of knowledge on stringed keyboard instruments. This knowledge of keyboard mechanisms and actions helped him to develop the first pianos. It is not known when Cristofori first built

18848-446: The piston and rotary valve by Heinrich Stölzel and Friedrich Blühmel , both Silesians , in 1815, was the first in a series of innovations which impacted the orchestra, including the development of modern keywork for the flute by Theobald Boehm and the innovations of Adolphe Sax in the woodwinds, notably the invention of the saxophone. These advances would lead Hector Berlioz to write a landmark book on instrumentation , which were

19000-515: The player piano replays the performance using pneumatic devices. Modern equivalents of the player piano include the Bösendorfer CEUS, Yamaha Disklavier and QRS Pianomation, using solenoids and MIDI rather than pneumatics and rolls. A silent piano is an acoustic piano having an option to silence the strings by means of an interposing hammer bar. They are designed for private silent practice, to avoid disturbing others. Edward Ryley invented

19152-480: The post until July 2014, the orchestra's longest serving chief conductor since Andreae. The orchestra made its debut at The Proms in September 2003 with Zinman, and his final concert as chief conductor was a July 2014 Proms appearance. During his tenure, Zinman introduced elements of historically informed performance into the orchestra's playing style and greatly expanded their recording presence. In October 2012,

19304-419: The pre-concert tuning and handles musical aspects of orchestra management, such as determining the bowings for the violins or the entire string section. The concertmaster usually sits to the conductor's left, closest to the audience. There is also a principal second violin, a principal viola, a principal cello, and a principal bass. The principal trombone is considered the leader of the low brass section, while

19456-528: The principal trumpet is generally considered the leader of the entire brass section. While the oboe often provides the tuning note for the orchestra (due to a 300-year-old convention), there is generally no designated principal of the woodwind section (though in woodwind ensembles, the flute is often the presumptive leader). Instead, each principal confers with the others as equals in the case of musical differences of opinion. Most sections also have an assistant principal (or co-principal or associate principal), or in

19608-418: The production of massive iron frames that could withstand the tremendous tension of the strings. Over time, the tonal range of the piano was also increased from the five octaves of Mozart's day to the seven octave (or more) range found on today's pianos. Early technological progress in the late 18th century owed much to the firm of Broadwood . John Broadwood joined with another Scot, Robert Stodart, and

19760-450: The rim was constructed from several pieces of solid wood, joined and veneered, and European makers used this method well into the 20th century. A modern exception, Bösendorfer (an Austrian manufacturer of high-quality pianos) constructs their inner rims from solid spruce, the same wood that the soundboard is made from, which is notched to allow it to bend; rather than isolating the rim from vibration, their "resonance case principle" allows

19912-587: The saxophone is included in other works, such as Ravel's Boléro , Sergei Prokofiev 's Romeo and Juliet Suites 1 and 2 , Vaughan Williams ' Symphonies No. 6 and No. 9 , and William Walton 's Belshazzar's Feast , and many other works as a member of the orchestral ensemble. The euphonium is featured in a few late Romantic and 20th century works , usually playing parts marked "tenor tuba", including Gustav Holst 's The Planets , and Richard Strauss 's Ein Heldenleben . The Wagner tuba ,

20064-413: The second violins playing in lower registers than the first violins, playing an accompaniment part, or harmonizing the melody played by the first violins. The principal first violin is called the concertmaster (or orchestra "leader" in the U.K.) and is not only considered the leader of the string section, but the second-in-command of the entire orchestra, behind only the conductor. The concertmaster leads

20216-403: The soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound." Hardwood rims are commonly made by laminating thin (hence flexible) strips of hardwood, bending them to the desired shape immediately after the application of glue. The bent plywood system was developed by C.F. Theodore Steinway in 1880 to reduce manufacturing time and costs. Previously,

20368-402: The soundboard is made of spruce boards glued together along the side grain. Spruce's high ratio of strength to weight minimizes acoustic impedance while offering strength sufficient to withstand the downward force of the strings. The best piano makers use quarter-sawn , defect-free spruce of close annular grain, carefully seasoning it over a long period before fabricating the soundboards. This

20520-417: The string, such as rust on plain strings and dirt in the windings of bass strings. The higher the partial, the further sharp it runs. Pianos with shorter and thicker string (i.e., small pianos with short string scales) have more inharmonicity. The greater the inharmonicity, the more the ear perceives it as harshness of tone. The inharmonicity of piano strings requires that octaves be stretched , or tuned to

20672-418: The strings are placed in two separate planes, each with its own bridge height, allowed greater length to the bass strings and optimized the transition from unwound tenor strings to the iron or copper-wound bass strings. Over-stringing was invented by Pape during the 1820s and first patented for use in grand pianos in the United States by Henry Steinway Jr. in 1859. Some piano makers added variations to enhance

20824-448: The strings when the sustain pedal is depressed, key release, the drop of the dampers, and simulations of techniques such as re-pedalling. Digital, MIDI-equipped pianos can output a stream of MIDI data, or record and play MIDI format files on digital storage media, similar in concept to a pianola. The MIDI file records the physics of a note rather than its resulting sound and recreates the sounds from its physical properties (e.g., which note

20976-464: The strings. Inharmonicity is the degree to which the frequencies of overtones (known as partials or harmonics ) sound sharp relative to whole multiples of the fundamental frequency. This results from the piano's considerable string stiffness; as a struck string decays, its harmonics vibrate from a point very slightly from its termination toward the center (or more flexible part) of the string. The inharmonicity may also result from imperfections within

21128-420: The strings. The sustain pedal allows pianists to connect and overlay sound, and achieve expressive and colorful sonority. In the 19th century, influenced by Romantic music trends, the fortepiano underwent changes such as the use of a cast iron frame (which allowed much greater string tensions) and aliquot stringing which gave grand pianos a more powerful sound, a longer sustain, and a richer tone. Later in

21280-437: The sustain pedal is depressed) and full pedal sets can now be replicated. The processing power of digital pianos has enabled highly realistic pianos using multi-gigabyte piano sample sets with as many as ninety recordings, each lasting many seconds, for each key under different conditions (e.g., there are samples of each note being struck softly, loudly, with a sharp attack, etc.). Additional samples emulate sympathetic resonance of

21432-411: The time-honored season-subscription system became increasingly anachronistic, as more and more listeners would buy tickets on an ad-hoc basis for individual events. Orchestral endowments and — more centrally to the daily operation of American orchestras — orchestral donors have seen investment portfolios shrink, or produce lower yields, reducing the ability of donors to contribute; further, there has been

21584-415: The tone of each note, such as Pascal Taskin (1788), Collard & Collard (1821), and Julius Blüthner , who developed Aliquot stringing in 1893. These systems were used to strengthen the tone of the highest register of notes on the piano, which up until this time were viewed as being too weak-sounding. Each used more distinctly ringing, undamped vibrations of sympathetically vibrating strings to add to

21736-542: The tone, except the Blüthner Aliquot stringing , which uses an additional fourth string in the upper two treble sections. While the hitchpins of these separately suspended Aliquot strings are raised slightly above the level of the usual tri-choir strings, they are not struck by the hammers but rather are damped by attachments of the usual dampers. Eager to copy these effects, Theodore Steinway invented duplex scaling , which used short lengths of non-speaking wire bridged by

21888-406: The top orchestras, occasionally fake certain passages. One reason that musicians fake is because there are not enough rehearsals. Another factor is the extreme challenges in 20th century and 21st century contemporary pieces; some professionals said "faking" was "necessary in anything from ten to almost ninety per cent of some modern works". Professional players who were interviewed were of

22040-626: The various European regions. The Baroque orchestra ranged from smaller orchestras (or ensembles) with one player per part, to larger-scale orchestras with many players per part. Examples of the smaller variety were Bach's orchestras, for example in Koethen, where he had access to an ensemble of up to 18 players. Examples of large-scale Baroque orchestras would include Corelli's orchestra in Rome which ranged between 35 and 80 players for day-to-day performances, being enlarged to 150 players for special occasions. In

22192-408: The way the piano was strung. There are one string for each note in the bass, two for each note in the tenor, and three for each note in the tenor. The use of a Capo d’Astro bar instead of agraffes in the uppermost treble allowed the hammers to strike the strings in their optimal position, greatly increasing that area's power. The implementation of over-stringing (also called cross-stringing ), in which

22344-470: The world's top five by Gramophone in 2008). The last major orchestra to appoint a woman to a permanent position was the Berlin Philharmonic . In February 1996, the Vienna Philharmonic's principal flute, Dieter Flury , told Westdeutscher Rundfunk that accepting women would be "gambling with the emotional unity ( emotionelle Geschlossenheit ) that this organism currently has". In April 1996,

22496-424: Was arranged like a grand set on end, with the soundboard and bridges above the keys and tuning pins below them. " Giraffe pianos ", " pyramid pianos " and " lyre pianos " were arranged in a somewhat similar fashion, using evocatively shaped cases. The very tall cabinet piano was introduced about 1805 and was built through the 1840s. It had strings arranged vertically on a continuous frame with bridges extended nearly to

22648-537: Was designing a stringed keyboard instrument in which the notes are struck by a hammer. The hammer must strike the string but not remain in contact with it, because continued contact would damp the sound and stop the string from vibrating and making sound. This means that after striking the string, the hammer must quickly fall from (or rebound from) the strings. Moreover, the hammer must return to its rest position without bouncing violently (thus preventing notes from being re-played by accidental rebound), and it must return to

22800-411: Was manufactured from the mid-1930s until recent times. The low position of the hammers required the use of a "drop action" to preserve a reasonable keyboard height. Modern upright and grand pianos attained their present, 2000-era forms by the end of the 19th century. While improvements have been made in manufacturing processes, and many individual details of the instrument continue to receive attention, and

22952-490: Was struck and with what velocity). Computer based software, such as Modartt's 2006 Pianoteq , can be used to manipulate the MIDI stream in real time or subsequently to edit it. This type of software may use no samples but synthesize a sound based on aspects of the physics that went into the creation of a played note. By the 2000s, some pianos included an acoustic grand piano or upright piano combined with MIDI electronic features. Such

23104-403: Was the first to use in pianos in 1826, was a more consistent material, permitting wider dynamic ranges as hammer weights and string tension increased. The sostenuto pedal ( see below ), invented in 1844 by Jean-Louis Boisselot and copied by the Steinway firm in 1874, allowed for a wider range of effects. One innovation that helped create the powerful sound of the modern piano was the use of
