Music Box: Loop Studio

Make music by filtering, previewing and layering original beat loops in a 16-step sequencer.

Pick a vibe. Build your beat. Share it. Music Box is a pocket music studio for your browser. Choose a genre and mood, find sounds that fit, and layer drums, bass, chords and melody into a beat that loops in perfect time. Then turn it into a full song and share it with friends or our community. No music theory needed.
