Piano is a keyboard instrument in which pressing a key makes a hammer strike a string to produce sound. Its wide range and dynamic expression make it widely used for solo performance, accompaniment, and as a composition tool. Electric pianos and digital keyboards implement the same key layout electronically. When connected to a computer, it exchanges performance data over MIDI, which can be used to build learning programs that guide the keys with LEDs or score a performance.
