Three octaves, every key labelled. Tap any key to hear it. Play freely, or pick a piece below and play it note by note — the score shows you what comes next.
The leftmost white key is C3 and it runs up to C6. Middle C is C4. The first tap unlocks sound.
Pick a melody and play it on the keyboard below. The highlighted note is the one to play next; notes you have played turn grey. Octave does not matter. “Hear it” plays the tune for you first.
