Wiggly Music - Draw lines that become music
Wiggly Music is a free browser visual music instrument. You draw lines and shapes on a canvas: left-to-right is time, up-down is pitch, and color is voice. Adjust key, scale, tempo and swing, play with MIDI, then export WAV or MIDI. It is not AI music generation — your drawing is the score. Try it at https://wigglymusic.com/
