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.
