109-577: American Piano Company ( Ampico ) was an American piano manufacturer formed in 1908 through the merger of Wm. Knabe & Co. , Chickering & Sons , Marshall & Wendell, and Foster-Armstrong. They later purchased the Mason & Hamlin piano company as their flagship piano. The merger created one of the largest American piano manufacturers. In 1932, it was merged with the Aeolian Company to form Aeolian-American Co. From 1914, American Piano

218-561: 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

327-587: 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

436-410: 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

545-420: A speaker enclosure to produce the sound the performer and audience hears. On electric pianos , the player presses or strikes keys, which cause hammers to strike metal tines. A magnetic pickup senses these vibrations, using the same approach as with an electric guitar (amplifier and speaker). Typically, the bridge is perpendicular to the strings and larger surface (which are roughly parallel to one another) with

654-408: 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

763-420: A bridge support and "feet" made of wood and a plastic or bone "ridge" where the strings are positioned against. A classical guitar saddle sits loosely in the hardwood bridge, held in place by string tension. Strings pass through shallow grooves in the saddle, at least for the treble strings, which prevents them moving around during hard playing. Yet another type of multi-part bridge is common on instruments with

872-414: 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

981-437: 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,

1090-445: A curved sound plate, such as an arch-top guitar or mandolin . Such instruments often have a bridge with a base and separate saddle that can be adjusted for height. On classical and flat-top guitars the bridge is glued to the top. A bridge held on to the top by string tension, as in banjos and archtop jazz guitars , is called a floating bridge , and requires a separate tailpiece to anchor the strings. Electric guitars typically have

1199-483: 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

1308-636: 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,

1417-627: 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

1526-525: 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

1635-465: A legacy of 19th and early 20th century aesthetic and musical practice. By the end of 1932, Ampico suffered economic difficulties and was finally merged with the Aeolian Company , manufacturer of player pianos and organs. The combined company, known as Aeolian-American Corp., went through several ownership changes before declaring bankruptcy in 1985. The Ampico reproducing player piano system

1744-478: 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

1853-613: 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

1962-475: A metal bridge, often with adjustable intonation screws. Bridge pins or string pegs are used on some musical instruments to locate the string precisely in the horizontal plane, and in the case of harpsichords to affect the sustain of the strings. They are usually made of steel in modern pianos , of brass in harpsichords , and bone or synthetics on acoustic guitars . Electric guitars do not usually have bridge pins as with guitars, they are used to transfer

2071-417: 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

2180-400: 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

2289-441: 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

2398-439: 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

2507-476: 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

2616-419: 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,

2725-471: 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

2834-434: 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

2943-454: 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

3052-420: A significant distance instead. This enables control of sustain and tone in harpsichord design (as per external link). For the larger, deeper violin family instruments, the bridge pin may have an extendable " endpin " which raises the instrument up. The bridge of the classical guitar does not use bridge pins. In this instrument the strings are tied to the part of the bridge called the tie block. Strings run over

3161-472: A single piece of material, most commonly wood for violins and acoustic guitars, that fits between the strings and the resonant surface. Alternatively, a bridge may consist of multiple parts. One common form is a bridge with a separate bearing surface, called a saddle , that supports the strings. This is often of a material harder than the bridge itself, such as bone, ivory, high-density plastic, or metal. Some acoustic guitar bridges have multiple materials, such as

3270-596: 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

3379-660: 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

3488-465: 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

3597-419: 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

3706-580: 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

3815-481: Is the result. Vibrato bridges usually must be suspended in some way, which reduces contact. Most vibrato system designs use a group of springs in the guitar body, which oppose the tension of the strings. Some players feel that the vibration of the springs affects resonance in a way that makes the guitar sound better, but others disagree. Many electric guitar playing styles require a vibrato system, either "locking" or "non-locking". Non-locking (or vintage) tremolos are

3924-448: Is the same material that is used in quality acoustic guitar soundboards. Low-cost pianos often have plywood soundboards. Bridge (instrument) Most stringed instruments produce sound through the application of energy to the strings, which sets them into vibratory motion, creating musical sounds. The strings alone, however, produce only a faint sound because they displace only a small volume of air as they vibrate. Consequently,

4033-594: 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

4142-453: 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,

4251-791: 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

4360-616: 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

4469-426: The tension of the strings pressing down on the bridge and thus on the larger surface beneath it. That larger, more acoustically responsive surface may be coupled to a sound chamber—an enclosure such as the body of a guitar or violin —that provides resonance that helps amplify the sound. Depending on the type of stringed instrument, the resonant surface the bridge rests on may be made of: Bridges may consist of

4578-549: 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

4687-597: The "Synchronized Tremolo" type and an almost endless stream of copies. The Bigsby vibrato tailpiece is another option. A locking tremolo uses a bridge that has a small clamp in each saddle to hold the strings in place (usually adjusted with an Allen key ). The nut at the end fingerboard also clamps the strings to hold them in place. This arrangement is especially useful for playing that requires tapping or heavy "bending" playing styles, such as shred guitar "dive bombing" effects. Locking tremolos provide excellent stability, but their fulcrum points provide minute contact with

4796-410: 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

4905-522: 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,

5014-473: 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

Modern pianos have

5232-430: The 19th century, is a small piano-like instrument that generally uses round metal rods to produce sound, rather than strings. 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

5341-660: The American Piano Company was the largest distributor and manufacturer of pianos in the world by the mid-1920s. The instrument's popularity reached its peak that decade thanks to a growth in prosperity and an increased interest in music stimulated by phonographs and radio. Piano producers across the country would not fare as well the following decade. Over 347,000 pianos were purchased in the United States in 1923, . Ampico reproducing pianos, and their associated piano rolls were rediscovered by collectors in

5450-618: The Bigsby lever used on vintage instruments. However, the "Synchronized Tremolo" type found on the Fender Stratocaster is balanced against a set of screws in much the same manner as a locking tremolo. Given that this type of tremolo is installed on solid body guitars the degree to which sound transfer affects the sound that the instrument produces is minimal. Also, keeping a guitar with a non-locking tremolo in tune can be difficult. The most common types of non-locking tremolos are

5559-536: The Fender Rhodes, became important instruments in 1970s funk and jazz fusion and in some rock music genres. 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

5668-480: The area, the village of East Rochester was also home to a musical manufacturing giant for the better part of the 20th century. Nestled in between the New York Central Railroad tracks and Commercial Street, the 250,000 square-foot edifice designed by Henry Ives was the first industrial building in the United States to be constructed from reinforced concrete. Renowned for its fine craftsmanship,

5777-405: 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 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

5886-418: The best of both of the older instruments, combining the ability to play at least as loudly as a harpsichord with the ability to continuously vary dynamics by touch. 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

5995-424: The body, which might disturb sound transfer. It is generally thought that non-tremolo bridges offer better transfer of string vibration into the body. This is due to direct contact of the bridge to the guitar's body. These bridges bolt directly to the guitar body. Assuming the bridge is of good quality , it limits longitudinal string movement, providing tuning stability. The improved transfer of string vibration into

6104-450: The bridge bends to and fro along the string direction at twice the rate of the string vibration. This causes the sounding board to vibrate at the same frequency as the string producing a wave-like motion and an audible sound. Instruments typically use a hollow, resonant chamber (violin bodies, guitar bodies) or a pickup and an amplifier/speaker to make this sound loud enough for the performers and audience to hear. Bridges are designed to hold

6213-530: The bridge saddle, through drilled holes in the base of the tie block, loop over the top of the tie block, loop under the strings and are tied on. A variation called the 18 hole bridge uses three holes per string and eliminates the need to tie the string down. The bridge must transfer vibration of the strings to the sound board or other amplifying surface. As the strings are set in motion (whether by picking or strumming, as with guitars, by bowing, with violin family instruments, or by striking them, as with pianos),

6322-490: The bridges found on guitars manufactured prior to the advent of the Floyd Rose locking tremolo in the late 1970s and many (typically cheaper) guitars manufactured thereafter. For many playing styles, vintage tremolos are a good choice because they are easy to use and maintain and have very few parts. Some people feel that they can also provide a better degree of sound transfer, especially with tailpiece type tremolos such as

6431-511: 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

6540-418: 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

6649-511: The floor, behind the keyboard and very large sticker action . The short cottage upright or pianino with vertical stringing—made popular by Robert Wornum around 1815—was built into the 20th century. They are informally called birdcage pianos because of their prominent damper mechanism. The oblique upright, popularized in France by Roller & Blanchet during the late 1820s, was diagonally strung throughout its compass. The tiny spinet upright

6758-540: 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

6867-448: 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

6976-415: 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

7085-552: 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

7194-532: 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

7303-605: 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

7412-510: 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

7521-408: 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

7630-500: 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

7739-410: 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

7848-545: 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

7957-451: The opposite end of the instrument from the bridge or tailpiece (typically where the head holding the tuning pegs joins the fingerboard), serves a similar string-spacing function. As well, like the bridge, the nut's height determines how high the strings are from the fingerboard. Bridges for electric guitars can be divided into two main groups, " vibrato " and "non-vibrato" (also called "hard-tail"). Vibrato bridges have an arm or lever (called

8066-548: 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

8175-467: 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

8284-437: 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

8393-439: 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

8502-547: 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

8611-561: 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

8720-523: 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

8829-438: The playing style, but, in general, a non-vibrato bridge is thought to provide better tuning stability and a solid contact between the guitar body and the strings. A whammy bar bridge is important in some heavy metal music styles, such as shred guitar . Generally, the more contact the bridge has with the body (i.e., the lower the position), the better the sound transfer is into the body. A "warmer" sound with increased sustain

8938-418: 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

9047-450: 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

9156-407: The sound from the strings into the hollow body of the instrument as well as holding the strings in place. In pianos the pins are set precisely in line with the edges of the notches of the bridge. The precise and firm setting of the pins is a critical element of the piano's quality. Loose or inaccurate pinning commonly produces false beats and tonal irregularities. In harpsichords there tends to be

9265-428: The sound of the strings alone requires impedance matching to the surrounding air by transmitting their vibrations to a larger surface area that displaces a larger volume of air (and thus produces louder sounds). This calls for an arrangement that lets the strings vibrate freely, but also conducts those vibrations efficiently to the larger surface. A bridge is the customary means for accomplishing this. The bridge conducts

9374-403: 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,

9483-402: 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

9592-417: 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

9701-418: 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

9810-433: The strings at a suitable height above the fingerboard of the instrument. The ideal bridge height creates sufficient angularity in the string to create enough down force to drive the top, but places the strings sufficiently close to the fingerboard to make noting the strings easy. Bridge height may be fixed or alterable. Most violin-family bridges are carved by a luthier ; as such, the height can be changed, but only by taking

9919-421: The strings but provide no active control over string tension or pitch. That is, there is no "whammy bar" or lever. A small group of vibrato bridges have an extended tail (also called "longtail"). These guitars have more reverb and sustain in their sound, because of the string resonance behind the bridge. The Fender Jaguar is an example of such a guitar. All bridges have advantages, and disadvantages, depending on

10028-448: 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

10137-464: 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

10246-437: 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

10355-415: 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

10464-550: 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

10573-582: 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,

10682-402: The vibrations of the strings to a hollowed out chamber in a number of instruments (e.g., violin family , acoustic guitar , balalaika ). On electric guitars and electric basses, the bridge conducts the vibrations to the body, but the vibrations of the strings are typically sensed by a magnetic pickup , so that an electric signal is created, which is then connected to a guitar amplifier and

10791-562: The vibrato arm, tremolo arm, or "whammy bar") that extends from below the string anchoring point. It acts as a lever that the player can push or pull to change the strings' tension and, as a result, "bend" the pitch down or up. This means that this type of bridge produces vibrato (a pitch change) rather than actual tremolo , but the term "tremolo" is deeply entrenched in popular usage via some manufacturers (starting with Fender Stratocaster in 1954 ) naming their vibrato systems as "tremolo". Non-vibrato bridges supply an anchoring point for

10900-508: The violin into the repair shop. Many acoustic guitars have fixed bridges that a regular player cannot adjust. Some jazz guitars have a "floating bridge" which the player can reposition themself for different sounds and tones. In addition to supporting the strings and transmitting their vibrations, the bridge also controls the spacing between strings with shallow grooves cut in the bridge or its saddle. The strings sit in those grooves, thus are held in their proper lateral position. The nut , at

11009-408: 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

11118-424: 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

11227-537: 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

11336-546: Was discontinued in 1941. The last model introduced was the Ampico Spinet Reproducing Piano, which had all the functionality of a reproducing piano, and although having a low cost of $ 495, had modest sales. The first piano rolls specially coded for the Ampico were made by Rythmodik Music Corporation . Originally named Despatch after the transportation company that spawned several dozen car shops in

11445-411: 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

11554-505: Was one of the leading producers of player pianos , most notably their reproducing player known as the Ampico. The Ampico reproducing player piano was able to capture all the expression of the original performance, with dynamics and fine nuances other devices could not reproduce. Their main competitors in reproducing players were the Aeolian Duo-Art (1913) and Welte-Mignon (1905). The player piano and reproducing Ampico mechanism

11663-439: Was originally designed by Charles Fuller Stoddard (1876–1958) with Dr. Clarence Hickman joining the company in the mid-1920s. Distinguished classical and popular pianists such as Sergei Rachmaninoff (1873–1943), Leo Ornstein (1892–2002), Ferde Grofé (1892-1972), Winifred MacBride , Marguerite Melville Liszniewska , Marguerite Volavy (1886–1951), Adam Carroll, Frank Milne and others recorded for Ampico, and their rolls are

11772-494: 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

11881-403: 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
