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.
Almost every modern piano has 52 white keys and 36 black keys for a total of 88 keys (seven octaves plus a minor third, from A0 to C8). Many older pianos only have 85 keys (seven octaves from A0 to A7). Some piano manufacturers have extended the range further in one or both directions.
