Play Music Theory

Draw a line. Press play. Hear it become a music loop.

Play Music Theory: Draw Music is a visual instrument that turns shapes, colors and gestures into looping sound. Move left and right to choose when notes play. Move up and down for higher or lower notes. Choose from nine colors, each with its own synthesized voice.

No music theory required. Start with a doodle, build a rhythm and discover how sound can look.
