A piano on stage

The piano is a musical instrument played by means of a keyboard that produces sound by striking steel strings with felt hammers. The hammers immediately rebound allowing the strings to continue vibrating at their resonant frequency. These vibrations are transmitted through a bridge to a soundboard that amplifies them.

The piano is widely used in Western music for solo performance, chamber music, and accompaniment. It is also very popular as an aid to composing and rehearsal. Although not portable and often expensive, the piano's versatility and ubiquity have made it one of the most familiar musical instruments. It is sometimes classified as both a percussion and a stringed instrument. According to the Hornbostel-Sachs method of music classification, it is grouped with Chordophones.

The word piano is a shortened form of the word pianoforte, which is seldom used except in formal language and derived from the original Italian name for the instrument, clavicembalo [or gravicembalo] col piano e forte (literally harpsichord with soft and loud). This refers to the instrument's responsiveness to keyboard touch, which allows the pianist to produce notes at different dynamic levels by controlling the speed with which the hammers hit the strings.

History

Early history

Although there were earlier attempts to make stringed keyboard instruments with struck strings, most notably hammered dulcimers such as the santur and santoor, the invention of the modern piano is credited to Bartolomeo Cristofori of Padua, Italy, who was employed by Prince Ferdinand de Medici as the Keeper of the Instruments. It is not known exactly when Cristofori first built a piano. An inventory made by his employers, the Medici family, indicates the existence of a piano by the year 1700; another document of doubtful authenticity indicates a date of 1698. The three Cristofori pianos that survive today date from the 1720s.

Like many other inventions, the piano was founded on earlier technological innovations. The mechanisms of keyboard instruments such as the clavichord and the harpsichord were well known. In a clavichord the strings are struck by tangents, while in a harpsichord they are plucked by quills. Centuries of work on the mechanism of the harpsichord in particular had shown the most effective ways to construct the case, soundboard, bridge, and keyboard. Cristofori, himself an expert harpsichord maker, was well acquainted with this body of knowledge.

Cristofori's great success was in solving, without any prior example, the fundamental mechanical problem of piano design: the hammers must strike the string, but not remain in contact with the string (as a tangent remains in contact with a clavichord string) because this would damp the sound. Moreover, the hammers must return to their rest position without bouncing violently, and it must be possible to repeat a note rapidly. Cristofori's piano action served as a model for the many different approaches to piano actions that followed. While Cristofori's early instruments were made with thin strings and were much quieter than the modern piano, compared to the clavichord (the only previous keyboard instrument capable of minutely controlled dynamic nuance through the keyboard) they were considerably louder and had more sustaining power.

Cristofori's new instrument remained relatively unknown until an Italian writer, Scipione Maffei, wrote an enthusiastic article about it (1711), including a diagram of the mechanism. This article was widely distributed, and most of the next generation of piano builders started their work because of reading it. One of these builders was Gottfried Silbermann, better known as an organ builder. Silbermann's pianos were virtually direct copies of Cristofori's, with one important addition: Silbermann invented the forerunner of the modern damper pedal, which lifts all the dampers from the strings at once.

Silbermann showed Johann Sebastian Bach one of his early instruments in the 1730s, but Bach did not like it at that time, claiming that 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.

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 Johann Andreas Stein) and Anton Walter. Viennese-style pianos were built with wood frames, two strings per note, and had leather-covered hammers. Some of these Viennese pianos had 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 today for use in authentic-instrument performance of his music. The pianos of Mozart's day had a softer, clearer tone than today's pianos or English pianos, with less sustaining power. The term fortepiano is nowadays often used to distinguish the 18th-century instrument from later pianos.

Development of the modern piano

Comparison of piano sound

Further information: Innovations in the piano

In the period lasting from about 1790 to 1860, the Mozart-era piano underwent tremendous changes that led to the modern form of the instrument. This revolution was in response to a consistent preference by composers and pianists for a more powerful, sustained piano sound, and made possible by the ongoing Industrial Revolution with technological resources such as high-quality steel, called piano wire, for strings, and precision casting for the production of iron frames. Over time, the tonal range of the piano was also increased from the five octaves of Mozart's day to the 7⅓ or more octaves found on modern pianos.

Broadwood grand square action

Early technological progress owed much to the English firm of Broadwood, who already had a reputation for the splendour and powerful tone of its harpsichords. Broadwood constructed instruments that were progressively larger, louder, and more robustly constructed. They sent pianos to both Joseph Haydn and Ludwig van Beethoven, and were 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 were more robust, Viennese instruments were more sensitive.

Erard double pilot action

By the 1820s, the center of innovation had shifted to Paris, where the Érard firm manufactured pianos used by Frédéric Chopin and Franz Liszt. In 1821, Sébastien Érard invented the double escapement action, which permitted a note to be repeated even if the key had not yet risen to its maximum vertical position. This facilitated rapid playing. 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.

One of the major technical innovations that helped to create the sound of the modern piano was the use of a strong 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. The increased structural integrity of the iron frame allowed the use of thicker, tenser, and more numerous strings. In a modern grand the total string tension can approach 20 tons. The single piece cast iron frame 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 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.

Other innovations for the mechanism included the use of felt hammer coverings instead of layered leather hammers. Felt hammers, which were first introduced by Henri Pape in 1826, were 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 improved by the Steinway firm in 1874, allowed a wider range of effects.

Other important technical innovations of this era included changes to the way the piano was strung, such as the use of a "choir" of three strings rather than two for all but the lower notes, and the use of different stringing methods. With the over strung scale, also called "cross-stringing", the strings are placed in a vertically overlapping slanted arrangement, with two heights of bridges on the soundboard instead of just one. This permits larger, but not necessarily longer, strings to fit within the case of the piano. Over stringing was invented by Jean-Henri Pape during the 1820s, and first patented for use in grand pianos in the United States by Henry Steinway Jr. in 1859.

Duplex scaling: Treble strings of a 182 cm. grand piano. From lower left to upper right: dampers, main sounding length of strings, treble bridge, duplex string length, duplex bridge (long bar perpendicular to strings), hitchpins.

With duplexes or aliquot scales, which was patented in 1872 by Theodore Steinway, the different components of string vibrations are controlled by tuning their secondary parts in octave relationships with the sounding lengths. Similar systems developed by Blüthner (1872), as well as Taskin (1788), and Collard (1821) used more distinctly ringing undamped vibrations to modify tone.

Some early pianos had shapes and designs that are no longer in use. The square piano had horizontal strings arranged diagonally across the rectangular case above the hammers and with the keyboard set in the long side. This design is variously attributed to Silbermann and Frederici and was improved by Guillaume-Lebrecht Petzold and Alpheus Babcock. Built in quantity through the 1890s (in the United States), Steinways celebrated iron framed over strung squares and were more than two and a half times the size of Zumpe's wood framed instruments that were successful a century before. Their overwhelming popularity was due to inexpensive construction and price, with performance and sonority frequently restricted by simple actions and closely spaced strings.

The mechanism in upright pianos is perpendicular to the keys.

The tall, vertically strung upright was arranged with the soundboard and bridges perpendicular to keys, and above them so that the strings did not extend to the floor. Diagonally strung Giraffe, pyramid and lyre pianos employed this principle in more evocatively shaped cases. The term was later revived by many manufacturers for advertising purposes.

The very tall cabinet piano introduced by Southwell in 1806 and built through the 1840s had strings arranged vertically on a continuous frame with bridges extended nearly to the floor, behind the keyboard and very large sticker action. The short cottage upright or pianino with vertical stringing, credited to Robert Wornum around 1815, was built into the 20th century. They are informally called birdcage pianos because of their prominent damper mechanism. Pianinos were distinguished from the oblique, or diagonally strung upright made popular in France by Roller & Blanchet during the late 1820s. The tiny spinet upright 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 forms by the end of the 19th century. Improvements have been made in manufacturing processes, and many individual details of the instrument continue to receive attention.

History and musical performance

Main article: Piano history and musical performance

Much of the most widely admired piano repertoire, for example, that of Haydn, Mozart, and Beethoven, was composed for a type of instrument that is rather different from the modern instruments on which this music is normally performed today. Even the music of the Romantics, including Liszt, Chopin, Robert Schumann, Felix Mendelssohn and Johannes Brahms, was written for pianos substantially different from ours.

Types

Modern pianos come in two basic configurations (with subcategories): the grand piano and the upright piano.

Grand

Grand piano

Grand pianos have the frame and strings placed horizontally, with the strings extending away from the keyboard. This makes the grand piano a large instrument, for which the ideal setting is a spacious room with high ceilings for proper resonance. There are several sizes of grand piano. Manufacturers and models vary, but a rough generalization distinguishes the "concert grand", (between about 2.2 m to 3 m long) from the "parlor grand" (about 1.7 m to 2.2 m) and the smaller "baby grand" (which may be shorter than it is wide).

All else being equal, longer pianos with longer strings have better sound and lower inharmonicity of the strings. Inharmonicity is the degree to which the frequencies of overtones (known as partials, partial tones, or harmonics) depart from whole multiples of the fundamental frequency. Pianos with shorter, thicker, and stiffer strings (e.g., baby grands) have more inharmonicity. The longer strings on a concert grand can vibrate more freely than the shorter, thicker strings on a baby grand, which means that a concert grand's strings will have truer overtones. This is partly because the strings will be tuned closer to equal temperament in relation to the standard pitch with less "stretching" in the piano tuning (See: Piano tuning). Full-size grands are usually used for public concerts, whereas smaller grands, introduced by Sohmer & Co. in 1884, are often chosen for domestic use where space and cost are considerations.

Upright

Upright piano

Upright pianos, also called vertical pianos, are more compact because the frame and strings are placed vertically, extending in both directions from the keyboard and hammers. It is considered harder to produce a sensitive piano action when the hammers move horizontally, as the vertical hammer return is dependent on springs which are prone to wear and tear. The grand piano hammers return by gravity, hence their return will always remain more consistent than the vertical hammers, thus giving pianists better control of their playing. However, a well-regulated vertical piano will probably play smoother than a grand piano that has not been regulated for years, and the very best upright pianos now approach the level of some grand pianos of the same size in tone quality and responsiveness.

One noticeable advantage that the grand piano action has over the vertical action is that all grand pianos have a special repetition lever in the playing action that is absent in all verticals. This repetition lever, a separate one for every key, catches the hammer close to the strings as long as the keys are played repeatedly and fairly quickly. In this position, with the hammer resting on the lever, a pianist can play repeated notes, staccato, and trills with much more speed and control than is possible on a vertical piano. For recent advances, see Innovations in the piano.

Other types

Player piano

Toy pianos began to be manufactured in the 19th century. In 1863, Henri Fourneaux invented the player piano, which "plays itself" from a piano roll without the need for a pianist. The player piano is a piano that records a performance using rolls of paper with perforations, and then replays the performance using pneumatic devices. A modern equivalent for the player piano is the Yamaha Disklavier system, which uses solenoids and midi instead of pneumatics and rolls. Silent pianos, which allow a regular piano to be used converted to a digital instrument, are a recent innovation and are becoming more popular.

Irving Berlin played a special piano called the transposing piano, which was invented in 1801 by Edward Ryley. It had a lever under the keyboard used to alter the music to any key. One of Berlin's pianos is in the Smithsonian Museum. For much of his career, Berlin only knew how to play the black keys. But with his 'trick piano' he was no longer limited to the key of F-sharp.

A relatively recent development is the prepared piano, which is used in contemporary art music. A prepared piano is a standard grand piano which has had objects placed inside it before a performance in order to alter its sound, or which has had its mechanism changed in some way. The scores for music for prepared piano often instruct the pianist to insert pieces of rubber or small pieces of metal (screws or washers) in between the strings. These added items either mute the strings or create unusual vibrating sounds.

Since the 1980s, digital pianos have been available, which use digital sampling technology to reproduce the sound of each piano note. The best digital pianos are sophisticated, with features including working pedals, weighted keys, multiple voices, and MIDI interfaces. However, with current technology, it remains difficult to duplicate a crucial aspect of acoustic pianos, namely that when the damper pedal (see below) is depressed, the strings not struck vibrate sympathetically when other strings are struck, as well as the unique instrument-specific mathematical non-linearity of partials on any given unison. Since this sympathetic vibration is considered central to piano tone, many digital pianos do not sound the same as the best acoustic pianos. Progress is being made in this area by including physical models of sympathetic vibration in the synthesis software. Some higher end digital pianos, such as the Yamaha Clavinova series, produced in the last few years incorporate string resonance technology to overcome this limitation.

Keyboard

Keyboard

Almost every modern piano has 36 black keys and 52 white keys for a total of 88 keys (seven octaves plus a minor third, from A0 to C8). Many older pianos only have 85 keys (seven octaves from A0 to A7), while some manufacturers extend the range further in one or both directions.

Some Bösendorfer pianos extend the normal range downwards to F0, with one other model going as far as a bottom C0, making a full eight octave range. These extra keys are sometimes hidden under a small hinged lid that can be flipped down to cover the keys in order to avoid visual disorientation in a pianist unfamiliar with the extended keyboard. On others, the colours of the extra white keys are reversed (black instead of white).

The extra keys are added primarily for increased resonance from the associated strings; that is, they vibrate sympathetically with other strings whenever the damper pedal is depressed and thus give a fuller tone. Only a very small number of works composed for piano actually use these notes. More recently, the Stuart and Sons company has also manufactured extended-range pianos. On their instruments, the range is extended both down the bass to F0 and up the treble to F8 for a full eight octaves. The extra keys are the same as the other keys in appearance.

Small studio upright acoustical pianos with only 65 keys have been manufactured for use by roving pianists. Known as "gig" pianos and still containing a cast iron harp, these are comparatively lightweight and can be easily transported to and from engagements by only two men. As their harp is longer than that of a spinet or console piano, they have a stronger base sound that to some pianists is well worth the trade-off in range that a reduced key-set offers.

Pedals

Standard pedals

Piano pedals from left to right: una corda, sostenuto, and damper.

Main article: Piano pedals

Pianos have had pedals, or some close equivalent, since the earliest days. (In the 18th century, some pianos used levers pressed upward by the player's knee instead of pedals.) Most upright pianos, especially cheaper models have only two pedals; but every piano has at least a damper pedal and a soft pedal. Most grand pianos have three pedals: soft pedal (una corda), sostenuto, and damper (from left to right, respectively).

The sustain pedal (or, damper pedal) is often simply called "the pedal", since it is the most frequently used. It is placed as the rightmost pedal in the group. It lifts the dampers from all keys, sustaining all played notes, and altering the overall tone. The soft pedal or una corda pedal is placed leftmost in the row of pedals. In grand pianos, it shifts the entire action, including the keyboard, to the right, so that the hammers hit only two strings. In uprights, the pedal moves the hammers closer to the strings. The effect of both softens the note. The middle pedal, on grand pianos, is a sostenuto pedal that keeps raised any damper that was already raised at the moment the pedal is depressed. This makes it possible to sustain some notes (by depressing the sostenuto pedal before notes to be sustained are released) while the player's hands are free to play other notes. This can be useful for musical passages with pedal points and other otherwise tricky or impossible situations. In uprights, it is called the celeste or "practice" pedal, and drops a piece of felt between the hammers and strings, greatly muting the sounds.

There are also nonstandard variants. On vertical pianos, the middle pedal can be a bass sustain pedal: that is, when it is depressed, the dampers lift off the strings only in the bass section. This pedal would be used only when a pianist needs to sustain a single bass note or chord over many measures, while playing the melody in the treble section. On the largest Fazioli piano, there is a fourth pedal to the left of the principal three. This moves the entire keyboard closer to the strings, allowing the hammers to hit the strings with less force and produce a smaller sound.

Unusual pedals

An upright pedal piano

The rare transposing piano, of which Irving Berlin possessed an example, had a middle pedal that functioned as a clutch which disengages the keyboard from the mechanism, enabling the keyboard to be moved to the left or right with a lever. The entire action of the piano is thus shifted to allow the pianist to play music written in one key so that it sounds in a different key. The pedal piano, or pedalier piano, is a rare type of piano that includes a pedalboard, enabling bass register notes to be played with the feet, as is standard on the organ. There are two types of pedal piano: the pedal board may be an integral part of the instrument, using the same strings and mechanism as the manual keyboard, or, less frequently, it may consist of two independent pianos (each with its separate mechanics and strings) which are placed one above the other, a regular piano played by the hands and a bass-register piano played by the feet.

Construction

Many parts of a piano are made of materials selected for extreme sturdiness. In quality pianos, the outer rim of the piano is made of a hardwood, normally maple or beech. According to Harold A. Conklin, the purpose of a sturdy rim is so that "the vibrational energy will stay as much as possible in the soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound."

View from below of a 182-cm grand piano. In order of distance from viewer: softwood braces, tapered soundboard ribs, soundboard. The metal rod at lower right is a humidity control device.

The rim is normally made by laminating flexible strips of hardwood to the desired shape, a system that was developed by Theodore Steinway in 1880. The thick wooden braces at the bottom (grands) or back (uprights) of the piano are not as acoustically important as the rim, and are often made of a softwood, even in top-quality pianos, in order to save weight. The requirement of structural strength, fulfilled with stout hardwood and thick metal, makes a piano heavy; even a small upright can weigh 136 kg (300 lb), and the Steinway concert grand (Model D) weighs 480 kg (990 lb). The largest piano built, the Fazioli F308, weighs 691 kg (1520 lb).

The pinblock, which holds the tuning pins in place, is another area of the piano where toughness is important. It is made of hardwood, (often maple) and generally is laminated (built of multiple layers) for additional strength and gripping power. Piano strings (also called piano wire), which must endure years of extreme tension and hard blows, are made of high quality steel. They are manufactured to vary as little as possible in diameter, since all deviations from uniformity introduce tonal distortion. The bass strings of a piano are made of a steel core wrapped with copper wire, to increase their flexibility. For the acoustic reasons behind this, see Piano acoustics.

The plate, or metal frame, of a piano is usually made of cast iron. It is advantageous for the plate to be quite massive. Since the strings are attached to the plate at one end, any vibrations transmitted to the plate will result in loss of energy to the desired (efficient) channel of sound transmission, namely the bridge and the soundboard. Some manufacturers now use cast steel in their plates, for greater strength. The casting of the plate is a delicate art, since the dimensions are crucial and the iron shrinks by about one percent during cooling. The inclusion in a piano of an extremely large piece of metal is potentially an aesthetic handicap.

Piano makers overcome this handicap by polishing, painting, and decorating the plate; often plates include the manufacturer's ornamental medallion and can be strikingly attractive. In an effort to make pianos lighter, Alcoa worked with Winter and Company piano manufacturers to make pianos using an aluminum plate during the 1940s. The use of aluminum for piano plates, however, did not become widely accepted and was discontinued.

The numerous grand parts and upright parts of a piano action are generally hardwood (e.g. maple, beech. hornbeam). However, since World War II, plastics have become available. Early plastics were incorporated into some pianos in the late 1940s and 1950s, but proved disastrous because they crystallized and lost their strength after only a few decades of use. The Steinway firm once incorporated Teflon, a synthetic material developed by DuPont, for some grand action parts in place of cloth, but ultimately abandoned the experiment due to an inherent "clicking" which invariably developed over time. (Also Teflon is "humidity stable" whereas the wood adjacent to the Teflon will swell and shrink with humidity changes, causing problems.) More recently, the Kawai firm has built pianos with action parts made of more modern and effective plastics such as carbon fiber; these parts have held up better and have generally received the respect of piano technicians.

Ivorite and ebony keys on a modern Steinway & Sons concert grand piano.

The part of the piano where materials probably matter more than anywhere else is the soundboard. In quality pianos, this is made of solid spruce (that is, spruce boards glued together at their edges). Spruce is chosen for its high ratio of strength to weight. The best piano makers use close-grained, quarter-sawn, defect-free spruce, and make sure that it has been carefully dried over a long period of time before making it into soundboards. In cheap pianos, the soundboard is often made of plywood.

Piano keys are generally made of spruce or basswood, for lightness. Spruce is normally used in high-quality pianos. Traditionally, the black keys were made from ebony and the white keys were covered with strips of ivory, but since ivory-yielding species are now endangered and protected by treaty, plastics are now almost exclusively used. Also, ivory tends to chip more easily than plastic. Legal ivory can still be obtained in limited quantities. At one time, the Yamaha firm innovated a plastic called "Ivorine" or "Ivorite", since imitated by other makers, that mimics the look and feel of ivory.

Note by Note: The Making of Steinway L1037, a documentary from Steinway and Sons, describes the entire process of making one of their pianos.

Care and maintenance

Main articles: Care and maintenance of pianos and Piano tuning

A piano tuner

Pianos need regular tuning to keep them up to pitch, which is usually the internationally recognized standard concert pitch of A4 = 440 Hz. The hammers of pianos are voiced to compensate for gradual hardening, and other parts also need periodic regulation. Aged and worn pianos can be rebuilt or reconditioned. Often, by replacing a great number of their parts, they can be made to perform as well as new pianos. It is often felt, however, that older pianos are more settled and produce a warmer tone.

Piano moving should be done by trained piano movers using adequate manpower and the correct equipment for any particular piano's size and weight. Pianos are heavy yet delicate instruments. Over the years, professional piano movers have developed special techniques for transporting both grands and uprights which prevent damages to the case and to the piano's mechanics. The wikibook on packing and moving household goods mentioned here has a section devoted to piano moving with a section regarding the risks and dangers of DIY piano moving.

Role of the piano

See also: Social history of the piano

The piano at the social center in the 19th century (Moritz von Schwind, 1868)

The piano is a crucial instrument in Western classical music, jazz, film, television, and most other complex western musical genres. Since a large number of composers are proficient pianists – and because the piano keyboard offers an easy means of complex melodic and harmonic interplay – the piano is often used as a tool for composition.

Pianos were, and still are, popular instruments for private household ownership, especially among the middle and upper classes. Hence, pianos have gained a place in the popular consciousness, and are sometimes referred to by nicknames including: "the ivories", "the joanna", "the eighty-eight", and "the black(s) and white(s)", "the little joe(s)". Playing the piano is sometimes referred to as "tickling the ivories".
