The piano (an abbreviation of pianoforte) is a musical instrument played using a keyboard.

Description

The piano (an abbreviation of pianoforte) is a musical instrument played using a keyboard. It is widely used in classical and jazz music for solo performances, ensemble use, chamber music, accompaniment, and for composing and rehearsal. Although the piano is not portable and often expensive, its versatility and ubiquity have made it one of the world's most familiar musical instruments.

Role

The piano is a crucial instrument in Western classical music, jazz, film, television, and most other complex western musical genres. A large number of composers are proficient pianists—and because the piano keyboard offers an easy means of complex melodic and harmonic interplay—the piano is often used as a tool for composition.
