Letâs first of all take a look at an unlabeled piano keyboard layout, i.e. without the note names. The one shown in the first piano keyboard layout has two octaves, a total of 24 notes. In an 88 key piano, there are 36 black keys and 52 white keys.
The piano got its start as a modification of the harpsichord, which had 60 keys. The first pianos, therefore, usually had 60 keys. 60 keys represented five octaves, since there are 12 notes in an octave. As more and more pianos were made, composers began to write more music for the piano. It wasn't long before their compositions took them beyond the five octaves available on pianos at that time.
