The piano is a musical instrument which is played by means of a keyboard. Widely used in Western Music for solo performance, ensemble use, chamber music and accompaniment, the piano is also very popular as an aid to composing and rehearsal. Although not portable and often expensive, the piano's versatility and ubiquity have made it one of the most familiar musical instruments.
Pressing a key on the piano's keyboard causes a felt covered hammer to strike steel strings. The hammers rebound, allowing the strings to continue vibrating at their resonant frequency. These vibrations are transmitted through a bridge to a sounding board that couples the acoustic energy to the air so that it can be heard as sound. When the key is released, a damper stops the string's vibration. Pianos are sometimes classified as both a percussion and a stringed instrument
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.
Most pianos are about 150 cm wide. Short grand pianos such as a "baby grand" are about as long as they are wide, but a Concert Grand can measure up to 3.08 m (10 ft 1 in) perpendicular to its keyboard.
