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.
This means that the piano can play 88 different pitches (or notes), going from the deepest bass range to the highest treble. The black keys are for the accidentals (Fâ¯/Gâ­, Gâ¯/Aâ­, Aâ¯/Bâ­, Câ¯/Dâ­, and Dâ¯/Eâ­), which are needed to play in all twelve keys.
