127-520: RAK Studios is a recording studio complex, with residential facilities, used by Rak Records , and located near Regent's Park in central London , England. It was founded in 1976 by English record producer Mickie Most . The RAK complex resides within a Victorian building that was once a school and church hall before being owned by ATV and used for television program rehearsals before becoming RAK Studios in 1976. RAK has four recording rooms. Studios 1 and 2 house API mixing consoles ; Studio 3 has
254-561: 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
381-580: 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
508-410: 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
635-485: A telephone hybrid for putting telephone calls on the air, a POTS codec for receiving remote broadcasts , a dead air alarm for detecting unexpected silence , and a broadcast delay for dropping anything from coughs to profanity . In the U.S., stations licensed by the Federal Communications Commission (FCC) also must have an Emergency Alert System decoder (typically in the studio), and in

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
889-414: 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
1016-437: 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,
1143-401: A different machine, which records the combined signals (called printing ) to a 1 ⁄ 2 -inch two-track stereo tape, called a master . Before digital recording, the total number of available tracks onto which one could record was measured in multiples of 24, based on the number of 24-track tape machines being used. Most recording studios now use digital recording equipment, which limits
1270-475: 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
1397-622: 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,

#17330845760541524-613: 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
1651-525: 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
1778-750: A home studio is challenging because they are usually the loudest instruments. Acoustic drums require sound isolation in this scenario, unlike electronic or sampled drums. Getting an authentic electric guitar amp sound including power-tube distortion requires a power attenuator or an isolation cabinet , or booth. A convenient compromise is amplifier modeling , whether a modeling amp, preamp/processor, or software-based guitar amp simulator. Sometimes, musicians replace loud, inconvenient instruments such as drums, with keyboards, which today often provide somewhat realistic sampling . The capability of digital recording introduced by ADAT and its comparatively low cost, originally introduced at $ 3995, were largely responsible for
1905-481: A home studio via the Internet. Additional outside audio connections are required for the studio/transmitter link for over-the-air stations, satellite dishes for sending and receiving shows, and for webcasting or podcasting . Grand 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
2032-413: A large role in the recording process. With software, a powerful, good quality computer with a fast processor can replace the mixing consoles , multitrack recording equipment, synthesizers, samplers and effects unit (reverb, echo, compression, etc.) that a recording studio required in the 1980s and 1990s. A computer thus outfitted is called a digital audio workstation , or DAW. While Apple Macintosh
2159-444: A lesser amount of diffused reflections from walls to make a good-sounding room. A drummer, vocalist, or guitar speaker cabinet, along with microphones, is acoustically isolated in the isolation booth. A typical professional recording studio today has a control room , a large live room , and one or more small isolation booths . All rooms are soundproofed by varying methods, including but not limited to, double-layer 5/8" sheetrock with
2286-478: 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
2413-609: 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
2540-417: 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
2667-400: 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

#17330845760542794-441: 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
2921-439: 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
3048-468: 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
3175-419: 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,
3302-467: 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
3429-434: 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
3556-508: A regular stage or film set. In the era of acoustical recordings (prior to the introduction of microphones, electrical recording and amplification), the earliest recording studios were very basic facilities, being essentially soundproof rooms that isolated the performers from outside noise. During this era it was not uncommon for recordings to be made in any available location, such as a local ballroom, using portable acoustic recording equipment. In this period, master recordings were made by cutting
3683-410: A rotating cylinder (later disc) made from wax. Performers were typically grouped around a large acoustic horn (an enlarged version of the familiar gramophone horn). The acoustic energy from the voices or instruments was channeled through the horn to a diaphragm to a mechanical cutting lathe , which inscribed the signal as a modulated groove directly onto the surface of the master. Electrical recording
3810-454: 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: 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
3937-497: A selection of instruments in their live room, typically instruments, amplifiers and speaker cabinets that are large, heavy, and difficult to transport (e.g., a Hammond organ ) or infeasible (as in the case of a grand piano ) to hire for a single recording session. Having musical instruments and equipment in the studio creates additional costs for a studio, as pianos have to be tuned and instruments and associated equipment needs to be maintained. General-purpose computers rapidly assumed

4064-402: A signal from one or more of the microphones in the studio could be routed to the loudspeaker in the echo chamber; the sound from the speaker reverberated through the chamber and the enhanced signal was picked up by the microphone at the other end. This echo-enhanced signal, which was often used to sweeten the sound of vocals, could then be blended in with the primary signal from the microphone in
4191-414: A single take. In the 1970s the large recording companies began to adopt multi-track recording and the emphasis shifted to isolation and sound-proofing, with treatments like echo and reverberation added separately during the mixing process, rather than being blended in during the recording. Generally, after an audio mix is set up on a 24-track tape machine, the tracks are played back together, mixed and sent to
4318-596: 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
4445-656: 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
4572-408: A vibrant acoustic signature as the natural reverb enhanced the sound of the recording. In this period large, acoustically live halls were favored, rather than the acoustically dead booths and studio rooms that became common after the 1960s. Because of the limits of the recording technology, which did not allow for multitrack recording techniques, studios of the mid-20th century were designed around
4699-485: A vintage Neve VRP Legend console (previously at Abbey Road Studios ' Studio 2); and Studio 4 is a 9.1.4 Atmos Room with Genelec system, which also operates a comfortable stereo mix and production room. The RAK Mobile recording studio was a remote recording truck originally built in 1973 by former BBC engineer Doug Hopkins as the Trans European Audio Mobile, or TEAM. When approached by Mickie Most to rent
4826-428: Is a key goal, the musicians, singers, audio engineers and record producers still need to be able to see each other, to see cue gestures and conducting by a bandleader. As such, the live room, isolation booths, vocal booths and control room typically have windows. Amplified instruments, like electric guitars and digital keyboards, may be connected directly to the recording console using DI units and performance recorded in
4953-613: Is a specialized facility for recording and mixing of instrumental or vocal musical performances, spoken words, and other sounds. They range in size from a small in-home project studio large enough to record a single singer-guitarist, to a large building with space for a full orchestra of 100 or more musicians. Ideally, both the recording and monitoring (listening and mixing) spaces are specially designed by an acoustician or audio engineer to achieve optimum acoustic properties (acoustic isolation or diffusion or absorption of reflected sound reverberation that could otherwise interfere with
5080-409: Is essential to preserving the ability to fine-tune lines up to the last minute. Sometimes, if the rapport between the lead actors is strong enough and the animation studio can afford it, the producers may use a recording studio configured with multiple isolation booths in which the actors can see each another and the director. This enables the actors to react to one another in real time as if they were on
5207-465: 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

5334-419: 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 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
5461-580: 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
5588-487: Is used for most studio work, there is a breadth of software available for Microsoft Windows and Linux . If no mixing console is used and all mixing is done using only a keyboard and mouse, this is referred to as mixing in the box (ITB). OTB describes mixing with other hardware and not just the PC software. A small, personal recording studio is sometimes called a project studio or home studio . Such studios often cater to
5715-578: 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
5842-449: 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,
5969-511: The RCA company in the 1930s were crucial to the crooning style perfected by Bing Crosby , and the famous Neumann U 47 condenser microphone was one of the most widely used from the 1950s. This model is still widely regarded by audio professionals as one of the best microphones of its type ever made. Learning the correct placement of microphones is a major part of the training of young engineers, and many became extremely skilled in this craft. Well into
6096-780: 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
6223-600: 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
6350-537: 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
6477-410: The "aliquot" throughout much of the upper range of the piano, always in locations that caused them to vibrate sympathetically in conformity with their respective overtones—typically in doubled octaves and twelfths. 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

6731-518: 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,
6858-473: The 1940s. Aluminum piano plates were not widely accepted and were discontinued. 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
6985-573: The 1950s and 1960s, the sound of pop recordings was further defined by the introduction of proprietary sound processing devices such as equalizers and compressors, which were manufactured by specialist electronics companies. One of the best known of these was the Pultec equalizer which was used by almost all the major commercial studios of the time. With the introduction of multi-track recording , it became possible to record instruments and singers separately and at different times on different tracks on tape. In
7112-508: The 1960s, in the classical field it was not uncommon for engineers to make high-quality orchestral recordings using only one or two microphones suspended above the orchestra. In the 1960s, engineers began experimenting with placing microphones much closer to instruments than had previously been the norm. The distinctive rasping tone of the horn sections on the Beatles recordings " Good Morning Good Morning " and " Lady Madonna " were achieved by having

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

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 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

Computers are used for playing ads , jingles , bumpers , soundbites , phone calls, sound effects , traffic and weather reports , and now are able to perform full broadcast automation when no staff are present. Digital mixing consoles can be interconnected via audio over Ethernet . Network connections allow remote access , so that DJs can do shows from
8255-511: 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
8382-489: The concept of grouping musicians (e.g., the rhythm section or a horn section ) and singers (e.g., a group of backup singers ), rather than separating them, and placing the performers and the microphones strategically to capture the complex acoustic and harmonic interplay that emerged during the performance. In the 2000s, modern sound stages still sometimes use this approach for large film scoring projects that use large orchestras. Because of their superb acoustics, many of
8509-480: The consideration of the physical dimensions of the room itself to make the room respond to sound in the desired way. Acoustical treatment includes and the use of absorption and diffusion materials on the surfaces inside the room. To control the amount of reverberation, rooms in a recording studio may have a reconfigurable combination of reflective and non-reflective surfaces. Soundproofing provides sonic isolation between rooms and prevents sound from entering or leaving
8636-436: The control room. This greatly enhances the communication between the producer and engineer with the player, as studio mics, headphones and talkback are unnecessary. Recording studios are carefully designed around the principles of room acoustics to create a set of spaces with the acoustical properties required for recording sound with accuracy. Architectural acoustics includes acoustical treatment and soundproofing and also
8763-418: 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

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
9017-540: 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
9144-448: 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
9271-415: 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
9398-412: The inherent sound of the large recording rooms, many of the best studios incorporated specially-designed echo chambers , purpose-built rooms which were often built beneath the main studio. These were typically long, low rectangular spaces constructed from hard, sound-reflective materials like concrete, fitted with a loudspeaker at one end and one or more microphones at the other. During a recording session,
9525-542: 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
9652-578: 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
9779-605: 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
9906-591: The larger studios were converted churches. Examples include George Martin 's AIR Studios in London, Columbia Records 30th Street Studio in New York City, and Pythian Temple studio in New York. Facilities like the Columbia Records 30th Street Studio in New York and Abbey Road Studios in London were renowned for their identifiable sound—which was (and still is) easily identifiable by audio professionals—and for
10033-505: 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
10160-584: The mid-20th century often lacked isolation booths, sound baffles , and sometimes even speakers. A major reason that isolation was not used was that recordings in this period were typically made as live ensemble takes and all the performers needed to be able to see each other and the ensemble leader while playing. The recording engineers who trained in this period learned to take advantage of the complex acoustic effects that could be created through leakage between different microphones and groups of instruments, and these technicians became extremely skilled at capturing
10287-422: The mid-20th century, recordings were analog , made on 1 ⁄ 4 -inch or 1 ⁄ 2 -inch magnetic tape , or, more rarely, on 35 mm magnetic film , with multitrack recording reaching 8 tracks in the 1950s, 16 in 1968, and 32 in the 1970s. The commonest such tape is the 2-inch analog, capable of containing up to 24 individual tracks. Throughout the 1960s many pop classics were still recorded live in
10414-408: 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
10541-500: 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
10668-410: 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
10795-524: The number of available tracks only on the basis of the mixing console 's or computer hardware interface's capacity and the ability of the hardware to cope with processing demands. Analog tape machines are still used in some cases for their unique sonic characteristics. Radio studios are very similar to recording studios, particularly in the case of production studios which are not normally used on-air , such as studios where interviews are taped for later broadcast. This type of studio would normally have all of
10922-545: 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
11049-543: 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
11176-462: 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
11303-437: 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
11430-439: 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
11557-537: 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
11684-556: The piano's versatility, 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
11811-515: 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
11938-418: 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
12065-502: The property. A Recording studio in an urban environment must be soundproofed on its outer shell to prevent noises from the surrounding streets and roads from being picked up by microphones inside. Equipment found in a recording studio commonly includes: Not all music studios are equipped with musical instruments. Some smaller studios do not have instruments, and bands and artists are expected to bring their own instruments, amplifiers, and speakers. However, major recording studios often have
12192-450: 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
12319-459: The rise of project studios in the 1990s. Today's project studios are built around software-based DAWs running on standard PC hardware. An isolation booth is either a partially enclosed area in the live room or a completely separate small room built adjacent to the live room that is both soundproofed to keep out external sounds and keep in the internal sounds. Like all the other recording rooms in sound industry, isolation booths designed for having
12446-444: The same equipment that any other audio recording studio would have, particularly if it is at a large station, or at a combined facility that houses a station group, but is also designed for groups of people to work collaboratively in a live-to-air situation. Broadcast studios also use many of the same principles such as sound isolation, with adaptations suited to the live on-air nature of their use. Such equipment would commonly include
12573-401: The saxophone players position their instruments so that microphones were virtually inside the mouth of the horn. The unique sonic characteristics of the major studios imparted a special character to many of the most famous popular recordings of the 1950s and 1960s, and the recording companies jealously guarded these facilities. According to sound historian David Simons, after Columbia took over
12700-508: The seams offset from layer to layer on both sides of the wall that is filled with foam, batten insulation, a double wall, which is an insulated wall built next to another insulated wall with an air gap in-between, by adding foam to the interior walls and corners, and by using two panes of thick glass with an air gap between them. The surface densities of common building materials determines the transmission loss of various frequencies through materials. Thomas A. Watson invented, but did not patent,
12827-516: The skill of their staff engineers. As the need to transfer audio material between different studios grew, there was an increasing demand for standardization in studio design across the recording industry, and Westlake Recording Studios in West Hollywood was highly influential in the 1970s in the development of standardized acoustic design. In New York City, Columbia Records had some of the most highly respected sound recording studios, including
12954-495: The smaller independent studios were often owned by skilled electronics engineers who designed and built their own desks and other equipment. A good example of this is Gold Star Studios in Los Angeles, the site of many famous American pop recordings of the 1960s. Co-owner David S. Gold built the studio's main mixing desk and many additional pieces of equipment and he also designed the studio's unique trapezoidal echo chambers. During
13081-474: The sound and keep it from bleeding into the other microphones, allowing better independent control of each instrument channel at the mixing console . In animation, vocal performances are normally recorded in individual sessions, and the actors have to imagine (with the help of the director or a reader) they are involved in dialogue. Animated films often evolve rapidly during both development and production, so keeping vocal tracks from bleeding into each other
13208-408: The sound for analog or digital recording . The engineers and producers listen to the live music and the recorded "tracks" on high-quality monitor speakers or headphones . Often, there will be smaller rooms called isolation booths to accommodate loud instruments such as drums or electric guitar amplifiers and speakers, to keep these sounds from being audible to the microphones that are capturing
13335-401: The sound heard by the listener). Recording studios may be used to record singers, instrumental musicians (e.g., electric guitar, piano, saxophone, or ensembles such as orchestras), voice-over artists for advertisements or dialogue replacement in film, television, or animation, Foley , or to record their accompanying musical soundtracks. The typical recording studio consists of a room called
13462-403: 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,
13589-402: 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
13716-445: The soundproof booth for use in demonstrating the telephone with Alexander Graham Bell in 1877. There are variations of the same concept, including a portable standalone isolation booth and a guitar speaker isolation cabinet. A gobo panel achieves the same effect to a much more moderate extent; for example, a drum kit that is too loud in the live room or on stage can have acrylic glass see-through gobo panels placed around it to deflect
13843-474: The sounds from other instruments or voices, or to provide "drier" rooms for recording vocals or quieter acoustic instruments such as an acoustic guitar or a fiddle . Major recording studios typically have a range of large, heavy, and hard-to-transport instruments and music equipment in the studio, such as a grand piano , Hammond organ , electric piano , harp , and drums . Recording studios generally consist of three or more rooms: Even though sound isolation
13970-444: The specific needs of an individual artist or are used as a non-commercial hobby. The first modern project studios came into being during the mid-1980s, with the advent of affordable multitrack recording devices, synthesizers and microphones. The phenomenon has flourished with falling prices of MIDI equipment and accessories, as well as inexpensive direct to disk recording products. Recording drums and amplified electric guitar in
14097-417: 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
14224-418: 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
14351-448: 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
14478-464: 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
14605-435: The studio and mixed into the track as the master recording was being made. Special equipment was another notable feature of the classic recording studio. The biggest studios were owned and operated by large media companies like RCA, Columbia and EMI, who typically had their own electronics research and development divisions that designed and built custom-made recording equipment and mixing consoles for their studios. Likewise,
14732-437: 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
14859-415: 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
14986-542: 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
15113-571: The unique acoustic properties of their studios and the musicians in performance. It was not until the 1960s, with the introduction of the high-fidelity headphones that it became common practice for performers to use these to monitor their performance during recording and listen to playbacks. The use of different kinds of microphones and their placement around the studio is a crucial part of the recording process, and particular brands of microphones are used by engineers for their specific audio characteristics. The smooth-toned ribbon microphones developed by
15240-582: 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 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,
15367-408: 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
15494-424: 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
15621-442: Was common by the early 1930s, and mastering lathes were electrically powered, but master recordings still had to be cut into a disc, by now a lacquer, also known as an Acetate disc . In line with the prevailing musical trends, studios in this period were primarily designed for the live recording of symphony orchestras and other large instrumental ensembles. Engineers soon found that large, reverberant spaces like concert halls created
15748-537: 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
15875-411: 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
16002-490: 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
16129-403: 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
