You don’t need to have an instrument to play. Your opponent can hum or clap their part. This is a fun way for parents to join in.
Could you leave it to chance? 😬
Playing a riff or a chord progression takes a lot of repetition. Instead of playing it 10 times in a row try and roll a 20-sided dice and see what you get. It could be 1 or it could be 20. I guess you’re just gonna have to find out. Give it a roll!!!!
