Use your computer keyboard - ASDFGHJ for white keys,
WETYU for black keys - or just tap or swipe the keys on screen. With more than 1 octave chosen, use Z/X or the Octave buttons below the keyboard to move the computer-keyboard keys up and down, or tap the on-screen keys directly. All selected octaves fit on screen. (Ignored while microphone mode is on.)
Record your own song
Play your song on a real acoustic or digital piano near the microphone. We'll listen for each note and turn it into a playable song, so you can record across all 28 white keys if you like.
