Most modern pianos have a row of 88 black and white keys (52 white keys for the notes of the C Major scale (the notes C, D, E, F, G, A and B) and 36 shorter black keys, which are raised above the white keys, and set further back on the keyboard.
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.
