A piano is a keyboard instrument widely used in western music for accompaniment, composition, solo performance, and as a rehearsal aid. It produces sound by striking metal strings with felt hammers. The vibrations are transmitted to a soundboard by a bridge.
The word piano is a short form of the word "pianoforte", which is in turn derived from the original Italian name for the instrument, clavicembalo col piano e forte. Literally harpsichord with soft and loud, this refers to the ability of the piano to produce notes at different volumes depending on how hard its keys are pressed. The name "pianoforte" is considered a formal term and is seldom used.
As a keyboard stringed instrument, the piano is similar to the clavichord and harpsichord. The three instruments differ in the mechanism of sound production. In a harpsichord, strings are plucked by quills or similar material. In the clavichord, strings are struck by tangents which remain in contact with the string. In a piano, the strings are struck by hammers which immediately rebound, leaving the string to vibrate freely.
