Black keys are sharps or flats between most white-key pairs.
Why 88 keys became standard
The 88-key range covers the notes used by most classical, jazz, pop, and teaching repertoire without making the instrument impractically large.
How smaller keyboards compare
A 76-key keyboard removes some extreme low and high notes. A 61-key keyboard is enough for many beginner exercises, but some two-hand pieces eventually need more range.
Which size should a beginner learn on
A weighted 88-key instrument is ideal, but a 61-key keyboard can still teach note names, rhythm, chords, and simple songs.
Common piano and keyboard sizes

| 76 keys | Often E1 to G7 | Portable practice with wider range |
| 61 keys | Often C2 to C7 | Beginner songs and basic chords |
| 49 keys | Often C2 to C6 | Compact MIDI input and short exercises |
