Discover a new way to explore harmony

Composer’s Dice are a simple tool to spark musical ideas. Roll the dice to generate chords and melodies, then turn them into music.

Featured in my viral piano improvisation reels, where millions have watched the dice shape the music in real time.

How it works

Roll one for melody. Roll both for harmony.

• Pitch Die (D12) — selects the root or melody pitch
• Chord Die (D20) — determines the chord

The chord die is intentionally weighted so common harmonies appear more often, with rarer chords adding occasional surprise.

For composers, players, and creators.
