Make a little music.

Pick a color and draw. Each color has its own sound. Higher lines make higher notes; playback moves from left to right.

Press Play to hear your drawing loop. Try a new scale or tempo. The eraser removes a whole stroke; Undo brings it back.

Space: play / stop. B: draw. E: erase. Ctrl / ⌘ Z: undo.

Your drawing is stored in this browser. Save a project to edit later, or export PNG artwork and WAV audio. This is an independent implementation, not the original app.
