Most modern pianos have 88 keys — seven full octaves plus three additional notes. This has been the standard since the late 1800s.
Most modern pianos have 88 keys — a number that was not standardized until the late 1800s. The predecessor of the piano, the harpsichord, had only 60 keys. As composers pushed the boundaries of range, piano manufacturers added keys, eventually settling on 88 as the standard.
88 keys represent seven full octaves plus three additional notes, giving pianists ample range for nearly all music composed for the piano, from Baroque through contemporary.
Virtually all modern pianos manufactured today, including all Kawai pianos, feature 88 keys. A few exceptions exist: some portable digital pianos marketed for beginners may have 54 or 76 keys. However, for serious students, a full 88-key keyboard is strongly recommended.
