This fun, free, and user-friendly app initiates jam sessions and helps out songwriters. Jam Dice was designed by a professional studio producer and music teacher and is designed to be used to real musicians. The way it works: 1. Select any of the 12 keys 2. Pick either 2, 4, or 8 measures of music. 3. “Roll the Dice”, and get a chord progression in the key you’ve selected 4. Play Music! Here are our 3 favourite ways to use Jam Dice: 1.
