Sheet music
Drag a dot to raise or lower its note — watch it land on the staff beside it. Pull it further out and the note gets a longer value, and rings longer, too. Press play, or hit Space, and follow the cursor.
Vertices 3
Tempo 96 BPM
Phase 0
Numbers 3–9 set the vertex count. Arrow keys ←/→ rotate the phase. Space plays or pauses. On touch or mouse, use the buttons above and drag the dots directly. A full cycle of the shape is one melody, always under 10 seconds.
