Johann Mattheson (28 September 1681 – 17 April 1764) was a German composer, critic , lexicographer and music theorist . His writings on the late Baroque and early Classical period were highly influential, specifically, "his biographical and theoretical works were widely disseminated and served as the source for all subsequent lexicographers and historians".
118-454: A fortepiano [ˌfɔrteˈpjaːno] is an early piano . In principle, the word "fortepiano" can designate any piano dating from the invention of the instrument by Bartolomeo Cristofori in 1700 up to the early 19th century. Most typically, however, it is used to refer to the mid-18th to early-19th century instruments, for which composers of the Classical era , such as Haydn , Mozart , and
236-404: 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
354-561: 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
472-580: 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
590-410: 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
708-408: 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
826-414: 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
944-437: 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,
1062-540: A coloristic device. The fortepiano builders who followed Silbermann introduced actions that were simpler than the Cristofori action, even to the point of lacking an escapement , the device that permits the hammer to fall to rest position even when the key has been depressed. Such instruments were the subject of criticism, particularly in a widely quoted 1777 letter from Mozart to his father , but were simple to make and were widely incorporated into square pianos . One of
1180-514: A diagram of the action, the core of Cristofori's invention. That article was republished 1719 in a volume of Maffei's work, and then in a German translation (1725) in Johann Mattheson 's Critica Musica . The latter publication was perhaps the triggering event in the spread of the fortepiano to German-speaking countries (see below). Cristofori's instrument spread quite slowly at first, probably because, being more elaborate and harder to build than
1298-475: 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

#17330850043721416-622: 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,
1534-613: 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
1652-416: A gradually expanding range; his last piano compositions are for an instrument of about six and a half octaves. The range of most modern pianos, attained in the 19th century, is 7⅓ octaves. Fortepianos from the start often had devices similar to the pedals of modern pianos, but they were not always pedals; sometimes hand stops or knee levers were used instead. Like the modern piano, the fortepiano can vary
1770-525: 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
1888-500: A harpsichord, it was very expensive. For a time, the piano was the instrument of royalty, with Cristofori-built or -styled instruments played in the courts of Portugal and Spain. Several were owned by Queen Maria Barbara of Spain , who was the pupil of the composer Domenico Scarlatti . One of the first private individuals to own a piano was the castrato Farinelli , who inherited one from Maria Barbara on her death. The first music specifically written for piano dates from this period:
2006-496: A humble origin in the work of Johannes Zumpe , a maker who had immigrated from Germany and worked for a while in the workshop of the great harpsichord maker Burkat Shudi . Starting in the middle to late 1760s, Zumpe made inexpensive square pianos that had a very simple action, lacking an escapement, (sometimes known as the "old man's head"). Although hardly a technological advancement in the fortepiano, Zumpe's instruments proved very popular, being imitated outside England, and playing
2124-410: A louder, more robust sound than the Viennese one, though it required deeper touch and was less sensitive. The early English grand pianos by those builders physically resembled Shudi harpsichords, being very imposing, with elegant, restrained veneer work on the exterior. Unlike contemporary Viennese instruments, English grand fortepianos had three strings per note, rather than two. John Broadwood married
2242-478: 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
2360-413: A major role in the displacement of the harpsichord by the fortepiano. The square pianos were also the medium of the first public performances on the instrument in the 1760s, notably by Johann Christian Bach . Americus Backers , with John Broadwood and Robert Stodart , two of Shudi's workmen, produced a more advanced action than Zumpe's. That English grand action , with an escapement and check, enabled
2478-609: 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

#17330850043722596-417: A microtone piano manufactured by Pleyel in 1920. Abdallah Chahine later constructed his quartertone "Oriental piano" with the help of Austrian Hofmann . 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
2714-552: A much lighter case construction than the modern piano and, except for later examples of the early nineteenth century (already evolving towards the modern piano), it has no metal frame or bracing. The action and hammers are lighter, giving rise to a much lighter touch, which in well-constructed fortepianos is also very expressive. The range of the fortepiano was about four octaves at the time of its invention and gradually increased. Mozart wrote his piano music for instruments of about five octaves. The piano works of Beethoven reflect
2832-400: 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
2950-441: 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
3068-439: 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
3186-468: 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
3304-419: 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,
3422-508: A piano, the mechanism by which the hammers are made to strike fewer than the maximum number of strings, for which Cristofori used a hand stop. It is not clear whether the modern soft pedal descends directly from Cristofori's work or arose independently. Cristofori's invention attracted public attention as the result of a journal article written by Scipione Maffei and published 1711 in Giornale de'letterati d'Italia of Venice. The article included
3540-467: 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
3658-434: 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

3776-596: 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
3894-569: A sudden quarrel during a performance of Mattheson's opera Die unglückselige Kleopatra, Königin von Ägypten in 1704. Handel was saved only by a large button which turned aside Mattheson's sword. The two were afterwards reconciled and remained in correspondence for life: shortly after his friend's death, Mattheson translated John Mainwaring 's biography of Handel into German and had it published in Hamburg at his own expense (" auf Kosten des Übersetzers ") in 1761. After his death in 1764, Johann Mattheson
4012-656: 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
4130-409: A very weak tone. Cristofori's instruments instead used thicker, tenser strings, mounted on a frame considerably more robust than that of contemporary harpsichords. As with virtually all later pianos, in Cristofori's instruments the hammers struck more than one string at a time; Cristofori used pairs of strings throughout the range. Cristofori was also the first to incorporate a form of soft pedal into
4248-419: Is credited with the invention of the forerunner of the sustain pedal , which removes the dampers from all the strings at once, permitting them to vibrate freely. Silbermann's device was only a hand stop, and so could only be changed during a pause in the music. Throughout the Classical era , even when the more flexible knee levers or pedals had been installed, the lifting of all the dampers was used primarily as
4366-465: 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
4484-580: 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
4602-562: Is somewhat specialist in its connotations, and does not preclude using the more general term piano to designate the same instrument. Thus, usages like "Cristofori invented the piano" or "Mozart's piano concertos" are currently common and would probably be considered acceptable by most musicians. Fortepiano is used in contexts where it is important to make the precise identity of the instrument clear, as in (for instance) "a fortepiano recital by Malcolm Bilson". The use of "fortepiano" to refer specifically to early pianos appears to be recent. Even
4720-431: Is the same material that is used in quality acoustic guitar soundboards. Low-cost pianos often have plywood soundboards. Johann Mattheson Johann Mattheson was born on 28 September 1681 in Hamburg. The son of a prosperous tax collector, Mattheson received a broad liberal education and, aside from general musical training, took lessons in keyboard instruments , violin , composition and singing. By age nine he

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

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,

That publication was an isolated phenomenon, and James Parakilas conjectures that the publication was meant as an honor for the composer on the part of his royal patrons. Certainly there could have been no commercial market for fortepiano music while the instrument continued to be an exotic specimen. It appears that the fortepiano did not achieve full popularity until
5192-780: 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

People's opinions about
5428-462: 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
5546-600: 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
5664-537: 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.

This instrument has a braceless back and a soundboard positioned below the keys—long metal rods pull on

Some early pianos had shapes and designs that are no longer in use. The square piano (not truly square, but rectangular) was cross strung at an extremely acute angle above the hammers, with
5900-724: The 1760s, from which time the first records of public performances on the instrument are dated, and when music described as being for the fortepiano was first widely published. It was Gottfried Silbermann who brought the construction of fortepianos to the German-speaking nations. Silbermann, who worked in Freiberg in Germany, began to make pianos based on Cristofori's design around 1730. (His previous experience had been in building organs , harpsichords , and clavichords .) Like Cristofori, Silbermann had royal support, in his case from Frederick
6018-518: The 1820s, the center of piano innovation had shifted to Paris, where the Pleyel firm manufactured pianos used by Frédéric Chopin , and the Érard firm manufactured those used by Franz Liszt . 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,

Prior to this, a piano made almost entirely of aluminum was placed aboard the airship Hindenburg . 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

The US Library of Congress recognizes the toy piano as a unique instrument with the subject designation, Toy Piano Scores: M175 T69. In 1863, Henri Fourneaux invented the player piano , which plays itself from a piano roll . A machine perforates a performance recording into rolls of paper, and

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
6490-665: The Great of Prussia , who bought many of his instruments. Silbermann's instruments were famously criticized by Johann Sebastian Bach around 1736, but later instruments encountered by Bach in his Berlin visit of 1747 apparently met with the composer's approval. It has been conjectured that the improvement in Silbermann's instruments resulted from his having seen an actual Cristofori piano, rather than merely reading Scipione Maffei's article. The piano action Maffei described does not match that found in surviving 18th-century instruments. Silbermann
6608-401: The athleticism exercised by modern piano virtuosos, but did require exquisite sensitivity of touch. Stein put the wood used in his instruments through a very severe weathering process, generating cracks in the wood, into which he would insert wedges. That gave his instruments a considerable longevity, on which Mozart commented, and several instruments survive today. Stein's fortepiano business
6726-459: The authoritative Oxford English Dictionary does not record this usage, noting only that "fortepiano" is "an early name of the pianoforte". During the age of the fortepiano, "fortepiano" and "pianoforte" were used interchangeably, as the OED's attestations show. Jane Austen , who lived in the age of the fortepiano and herself played the instrument, used "pianoforte" (also: "piano-forte", "piano forte") for

The piano was invented by the harpsichord maker Bartolomeo Cristofori in Florence . The first reliable record of his invention appears in the inventory of the Medici family (who were Cristofori's patrons), dated 1700. Cristofori continued to develop

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

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,

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

#17330850043727316-531: 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

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

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

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

More and more music schools offer courses of study in the fortepiano. There are several fortepiano competitions, including the MAfestival Brugge and the International Chopin Competition on Chopin era instruments , organized by

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
8024-415: 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
8142-411: The instrument until the 1720s, the time from which the surviving three Cristofori instruments date. Cristofori is perhaps best admired today for his ingenious piano action, which in some ways was more subtle and effective than that of many later instruments. However, other innovations were also needed to make the piano possible. Merely attaching the Cristofori action to a harpsichord would have produced

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

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
8496-605: 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
8614-457: The late 19th century, the early music pioneer Arnold Dolmetsch built three fortepianos. However, that attempted revival of the instrument was evidently several decades ahead of its time, and did not lead to its widespread adoption. In the second half of the 20th century, a great upsurge of interest occurred in period instruments , including a revival of interest in the fortepiano. Old instruments were restored, and many new ones were built along
8732-505: 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
8850-546: The lines of the old. Fortepiano kits also became available. The ability of builders to recreate the fortepiano drew on the accumulating expertise of the builders who were making harpsichords of historical design; for instance fortepiano pioneer Philip Belt spent two years early in his career working as an apprentice for Frank Hubbard , a prominent builder of historical harpsichords. Other builders also took up fortepiano construction, including Margaret F. Hood , Rodney Regier, Chris Maene , and Paul McNulty . The reintroduction of
8968-431: The many occurrences of the instrument in her writings. 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:
9086-463: The master's daughter (Barbara Shudi, 1769) and ultimately took over and renamed the Shudi firm. The Broadwood company (which survives to this day) was an important innovator in the evolution of the fortepiano into the piano . Broadwood, in collaboration with Jan Ladislav Dussek , a noted piano virtuoso active in London in the 1790s, developed pianos that gradually increased the range to six octaves. Dussek
9204-405: The mid 19th century. The Viennese action was simpler than the Cristofori action, and very sensitive to the player's touch. According to Edwin M. Ripin (see references below), the force needed to depress a key on a Viennese fortepiano was only about a fourth of what it is on a modern piano, and the descent of the key only about half as much. Thus playing the Viennese fortepiano involved nothing like
9322-408: 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
9440-457: The most distinguished fortepiano builders in the era following Silbermann was one of his pupils, Johann Andreas Stein , who worked in Augsburg , Germany. Stein's fortepianos had (what we, or Cristofori, would call) "backwards" hammers, with the striking end closer to the player than the hinged end. This action came to be called the "Viennese" action, and was widely used in Vienna, even on pianos up to
9558-500: 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
9676-410: 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
9794-545: 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
9912-543: 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
10030-462: 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
10148-437: 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
10266-439: 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
10384-537: 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
10502-515: 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
10620-418: 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
10738-450: 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
10856-443: The sound of the fortepiano vary widely, both from person to person and from instrument to instrument. Here are three representative opinions about fortepianos: "Fortepiano" is Italian for "loud-soft", just as the formal name for the modern piano, "pianoforte", is "soft-loud". Both are abbreviations of Cristofori's original name for his invention: gravicembalo col piano e forte , "harpsichord with soft and loud". The term fortepiano
10974-452: The sound volume of each note, depending on the player's touch. The tone of the fortepiano is quite different from that of the modern piano, however, being softer, with less sustain . Sforzando accents tend to stand out more than on the modern piano, because they differ from softer notes in timbre as well as volume, and decay rapidly. Fortepianos also tend to have quite different tone quality in their different registers – slightly buzzing in
11092-403: 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,
11210-402: 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
11328-417: 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
11446-418: 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
11564-448: 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
11682-464: 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
11800-420: 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
11918-437: 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
12036-415: 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
12154-542: 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
12272-408: 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
12390-625: The younger Beethoven , wrote their piano music. Starting in Beethoven's time, the fortepiano began a period of steady evolution, culminating in the late 19th century with the modern grand . The earlier fortepiano became obsolete and was absent from the musical scene for many decades. In the later 20th century, the fortepiano was revived, following the rise of interest in historically informed performance . Fortepianos are built for that purpose, in specialist workshops. The fortepiano has leather -covered hammers and thin, harpsichord -like strings. It has
12508-546: Was Anton Walter , a friend of Mozart, who built instruments with a somewhat more powerful sound than Stein's. Although Mozart very much admired the Stein fortepianos, as the 1777 letter mentioned above makes clear, his own piano was a Walter. Haydn also owned a Walter piano, and even Beethoven expressed a wish to buy one. The fortepianos of Stein and Walter are widely used today as models for the construction of new instruments, discussed below. Still another important builder in that period
12626-484: Was Conrad Graf (1782–1851), who made Beethoven's last piano. Graf was one of the first Viennese makers to build pianos in quantity, as a large business enterprise. His instruments were played by Chopin , Mendelssohn and Schumann . Prominent piano makers among the French during the era of the fortepiano included Erard , Pleyel ( Chopin ’s favorite maker) and Boisselot ( Liszt ’s favorite). The English fortepiano had
12744-459: Was a brilliant polemicist and his theories on music are often full of pedantry and pseudo-erudition. The bulk of his compositional output was vocal, including eight operas, and numerous oratorios and cantatas . He also wrote a few sonatas and some keyboard music, including pieces meant for keyboard instruction. All of his music, except for one opera, one oratorio, and a few collections of instrumental music, went missing after World War II , but
12862-424: 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
12980-465: Was as a professional diplomat. He had studied English in school and spoke it fluently. He became tutor to the son of the English ambassador Sir John Wich and then secretary to the ambassador. He went on diplomatic missions abroad representing the ambassador. In 1709 he married Catharina Jennings, the daughter of an English clergyman; they did not have any children. Mattheson was a close friend of George Frideric Handel , although he nearly killed Handel in
13098-681: Was buried in the vault of Hamburg's St. Michaelis' Church where his grave can be visited. Mattheson is mainly famous as a music theorist. He was the most abundant writer on performance practice, theatrical style, and harmony of the German Baroque . He is particularly important for his work on the relationship of the disciplines of rhetoric and music, for example in Das neu-eröffnete Orchestre , Hamburg 1713, and Der vollkommene Capellmeister [ de ] , Hamburg 1739. However his books raise more and more attention and suspicion because Mattheson
13216-568: Was carried on in Vienna with distinction by his daughter Nannette Streicher , along with her husband Johann Andreas Streicher . The two were friends of Beethoven, and one of the composer's pianos was a Streicher. Later on, in the early 19th century, more robust instruments, with greater range, were built in Vienna, by (for example) the Streicher firm, which continued through two more generations of Streichers. Composer Johannes Brahms also preferred pianos by Streicher. Another important Viennese builder
13334-537: 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
13452-411: 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
13570-453: Was one of the first pianists to receive a 5½ foot piano and, in 1793, he wrote the first work for piano "with extra keys", a piano concert (C 97). The firm shipped a piano to Beethoven in Vienna, which the composer evidently treasured. From the late 18th century, the fortepiano underwent extensive technological development and evolved into the modern piano (for details, see Piano ). The older type of instrument eventually ceased to be made. In
13688-446: Was singing and playing organ in church and was a member of the chorus of the Hamburg opera. He made his solo debut with the Hamburg opera in 1696 in female roles and, after his voice changed, sang tenor at the opera, conducted rehearsals and composed operas himself. He was cantor at St. Mary's Cathedral, Hamburg from 1718 until increasing deafness led to his retirement from that post in 1728. Mattheson's chief occupation from 1706
13806-490: 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
13924-403: 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
