The piano was invented by Bartolomeo Cristofori of Padua, Italy. He made the first piano in 1709. The piano (an abbreviation of pianoforte) is a musical instrument played using a keyboard. A normal piano has 88 keys, 52 white & 36 black. There are two types of pianos and each varies in form and size: Vertical / Upright Pianos & Horizontal/Grand Pianos. It is widely employed in classical and jazz music for solo and ensemble performances, 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.
