What is piano?

The piano is a musical instrument played by me of a keyboard. It produces sound by striking steel strings with felt hammers that immediately rebound allowing the string to continue vibrating at its resonant frequency. These vibrations are trmitted through the bridges to the soundboard
which amplifies them. The piano is widely used in Western music for solo performance
chamber music
and acpaniment. It is also very popular as an aid to posing 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 string instrument (in a loose sense of that term). 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.
