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.
Unlike xylophones, which have up to 40 keys, or most woodwind instruments, which have a limited number of keys, pianos have a whopping 88 keys. Each key represents a different note, giving the piano a wide range of sounds.
