A prepared piano is a piano that has had its sounds temporarily altered by placing bolts, screws, mutes, rubber erasers, and/or other objects on or between the strings. Its invention is usually traced to John Cage, who used the technique in his dance music for Bacchanale (1940), created for a performance in a Seattle venue that lacked sufficient space for a percussion ensemble. Cage has cited Henry Cowell as an inspiration for developing piano extended techniques, involving strings within a piano being manipulated instead of the keyboard. Typical of Cage's practice, as summed up in the Sonatas and Interludes (1946–1948), is that each key of the piano has its own characteristic timbre, and that the original pitch of the string will not necessarily be recognizable. Further variety is available with use of the una corda pedal.
Between 1950 and 1980, Ferrante & Teicher used partially prepared pianos for some of their tunes in their albums. Other musicians, such as Denman Maroney, use prepared piano for performances. Cor Fuhler and Roger Miller have developed their own ways of using prepared piano in their musical albums. Additionally, notable contributors to the subsequent repertoire include Lou Harrison, Pauline Oliveros, James Tenney, and Christian Wolff.
When a properly prepared piano has been "unprepared", it should be impossible for anyone to tell that it had ever been prepared.[Bunger, Richard (1973). The Well-Prepared Piano. Colorado Springs: Colorado College Music Press] Changes causing less easily reversible damage can be served by permanently dedicating an instrument, such as the tack piano. Other techniques related to prepared piano include the Acoustisizer.
Historical precedents
Cage frequently cited
Henry Cowell (1897–1965) as the primary inspiration for the prepared piano.
[Nicholls, David (1991) 1st. American Experimental Music 1890–1940. Cambridge, New York, and Melbourne: Cambridge University Press. p. 523. .] Cowell pioneered piano extended techniques for what he dubbed "
string piano", involving reaching inside the piano and plucking, sweeping, scraping, thumping, and otherwise manipulating the strings directly, rather than using the keyboard. He developed these techniques in numerous pieces such as
Aeolian Harp (1923) and
The Banshee (1925).
[Bartók, Peter; Asch, Moses; Distler, Marian; and Cowell, Sydney. Revised by Sorrel Hays (1993) 1st. Liner notes to Henry Cowell: Piano Music (Smithsonian Folkways 40801). p. 12 (unpaginated)]
Pieces of paper were called for in several early 20th century works, the buzzing effect reminiscent of the parchment 'bassoon' pedal of early fortepianos. In his
Ragamalika (1912–1922), based on the classical music of India, French composer
Maurice Delage (1879–1961) calls for a piece of cardboard to be placed under the B in the second line of the bass clef to dampen the sound, imitating the sound of an Indian drum.

In his Chôros No. 8, a 1925 work for large orchestra, Heitor Villa-Lobos instructs the 2nd pianist to insert pieces of paper between the strings ["Mettre des papiers entre les cordes" at figure 48, a passage doubled by harp. ] Maurice Ravel's L'enfant et les sortilèges (1920-1925) calls for Luthéal, but allows piano with paper to substitute.[. The New Grove article cites this work in Edwin M. Ripin, revised by Hugh Davies and Thomas J. Kernan: Prepared piano]
John Cage
The invention of the "prepared piano",
per se, is usually traced to
John Cage. Cage first prepared a piano when he was commissioned to write music for
Bacchanale, a
dance by
Syvilla Fort (its date is variously given as 1938 or 1940). For some time previously, Cage had been writing exclusively for a
percussion ensemble, but the hall where Fort’s dance was to be staged had no room for a percussion group. The only instrument available was a single grand piano. After some consideration, Cage said that he realized it was possible "to place in the hands of a single pianist the equivalent of an entire percussion orchestra ... With just one musician, you can really do an unlimited number of things on the inside of the piano if you have at your disposal an exploded keyboard".

Ferrante & Teicher were an American piano duo who produced over a hundred albums of light classical and popular "easy listening" in their long careers (1947–1992). Between 1950 and 1980 they included partially prepared pianos on a number of their tunes to add percussive effects.

Cor Fuhler pioneered many inside piano techniques during the 1980s and recorded his first prepared piano solo album 7CC IN IO on GeestGronden in 1995; recorded The Hands of Caravaggio with John Tilbury and M.I.M.E.O. on the USA label Erstwhile Records; and in 2007 he released Stengam on the French label Potlatch.

Since 1982, Roger Miller has developed his own take on prepared piano in his work, initially on Mission of Burma's single "Trem II". Miller has since released many albums (on labels including Ace of Hearts, SST, New Alliance, Atavistic and Matador) incorporating this technique. His concert hall compositions since 2009 have often utilized prepared piano.

Tack piano
Strictly speaking, a tack piano is not a prepared piano, since
-
No objects are inserted into or onto the strings;
-
The strings' original pitches remain perceptible; and
-
The preparation is not fully reversible.
Although the tacks can be removed from the hammers, inserting them causes permanent damage to the felt; for this and other reasons, the use of tacks is generally discouraged by piano technicians.
Acoustisizer
The Acoustisizer is an electroacoustic musical instrument built from a small grand piano with built-in speakers, magnetic guitar pickups, PZMs, and
prepared piano strings. It was built as part of a graduate thesis project at California State University Dominguez Hills by Bob Fenger (1983), a student of Richard Bunger (author of the
Well Prepared Piano). Speakers are built into the bottom of the instrument, redirecting its own amplified sound back onto the sounding board, with strings and magnetic pickups creating an amplitude intensity loop, which in turn drives and vibrates suspended
kinetic oscillators (assemblages of vibration sensitive materials). Secondary control parameters allow extraction of vibration and sound phenomena from the
kinetic oscillators through a series of proximity microphones and
PZMs (piezo-electric contact mics). An article by the inventor was published in
Experimental Musical Instruments Magazine April 1991, Nicasio, California.
[Fenger, Bob Icon. "The Acoustisizer", Nicasio, California, volume 6, no. 6, April 1991.] It includes pictures of the
kinetic oscillators and stages of the construction process, including an underbody view of the speaker system configuration.
