Piano english introduction

Piano is a musical instrument played by keyboard, which produces sound by striking steel strings with a felt hammer. The hammer immediately bounces back, allowing the strings to continue to vibrate at the resonant frequency. These vibrations are transmitted through a bridge to a resonating plate, which amplifies them.

Piano is widely used in solo, ensemble, chamber music and accompaniment in western music. As an auxiliary means of composition and rehearsal, it is also very popular. Although inconvenient to carry and usually expensive, the versatility and ubiquity of the piano make it one of the most familiar musical instruments. It is sometimes classified as percussion and stringed instruments. According to Hornbostel-Sachs' music classification method, it is classified as a choir.

The word piano is an abbreviation of the word pianoforte, which is rarely used in formal language. It comes from the original Italian name of the instrument, clavicembalo[ or Gravecembalo] Colpiano e forte (literally meaning soft and loud harpsichord). This refers to the instrument's ability to respond to keyboard touch, which enables the pianist to produce different dynamic levels of notes by controlling the speed at which the hammer hits the strings.
