I was working on and asked for his help by having him lay down a basic groove. He came up with a little 4 chord something and I did exactly as you instructed. I wrote out each note of the 4 chords, made a scale out of them and started noodling. They seemed to fit. TellDunkin

We then recorded his little jam and played it back through one of our montiors so that he could jump on the drum kit. I started to play my scale. It wasn't music but things did seem to fit and it was entirely awesome to be jamming with my son!
