Sounds like a fun challenge. Start by defining a small set of chord progressions and a scale. Then pick a tempo and use a random generator to choose note lengths and intervals within that scale. To keep it emotional, you can bias the random choices toward larger intervals or syncopated rhythms. Add a simple algorithm for a solo – maybe a Markov chain trained on some of your favorite riffs. That way the output feels like a natural jam but still unpredictable. Remember to test it with a loop so you can hear how the randomness plays out before you hit record. Good luck, and feel free to throw more specifics my way if you hit a snag.
