Draw, and the drawing plays. Nine colors, each its own instrument. Lines become melodies as the playhead crosses them. Three programs: ink on paper, a pixel lattice, and a picture stage. Add beats, change the tempo, change keys, shuffle the drawing, or draw on the sky or an image of your choosing. Made by Tala Schlossberg. More at playmusictheory.net.
