The Piano

A piano is a keyboard instrument, widely used in western music for solo performance, chamber
music, and accompaniment, and also as a convenient aid to composing and rehearsal.

The piano produces sound by striking steel strings with felt hammers. These vibrations are
transmitted though the bridges to the soundboard.

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.

Bartolomeo Cristofori of Florence, Italy, invented the first pianoforte. He called it a gravicembalo
col piano e forte. When he built this instrument is not entirely clear, but an inventory made by
Cristofori's employers, the Medici family, indicates the existence of an early Cristofori instrument
by the year 1700. Cristofori built only about twenty pianofortes before he died in 1731; the three
that survive today date from the 1720s

The piano is a crucial instrument in Western classical music, jazz, film, television and electronic
game music, and most other complex western musical genres. A large number of composers being
proficient pianists, the piano is often used as a tool for composition.

Pianos were, and are, extremely 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)." Playing the piano is sometimes referred to as "tickling the ivories".
