10-hole diatonic · all 12 keys · bend notes · retune any reed
Tap the top row to blow and the bottom row to draw; slide sideways to move between holes.
Bend: while holding a note, drag outward (up on blow, down on draw). Notes only bend where a real harp can: draw bends on holes 1–6 and blow bends on 8–10 in standard tuning.
Keyboard: 1–0 blow, Q–P draw, hold Shift to bend.
