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.
In the Western tradition of music, there are basically twelve keys, corresponding to the twelve notes of the chromatic scale on a keyboard instrument (ie C, C#, D, D#...etc all the way up to C again). But as these can be either major or minor, we end up with a total of 12 major + 12 minor = 24 possible keys.
