The term "88 keys" typically refers to the standard number of keys on a full-sized piano. A traditional piano keyboard consists of 52 white keys and 36 black keys, which together allow musicians to play a wide range of notes and chords. This configuration enables the performance of various musical styles, from classical to jazz. In addition to pianos, many digital keyboards and synthesizers also feature 88 keys, providing a similar playing experience. The 88-key layout is favored by many pianists and composers for its versatility and ability to cover a broad spectrum of musical compositions, making it a staple in both practice and performance settings.
