An old friend of mine and I are going to start meeting twice a month to 'collaborate' on things musical. He's a great musician, lots of ideas, plays guitar, bass, piano, trumpet, all quite well. He has been out of touch with the music scene for a while, (long story, but he is a teaching golf pro now) and is missing it. I'm not sure what to expect out of this, but i want to be organized enough to get some things down on paper or in the computer and work on them between sessions. I see lots of opportunity to learn and maybe do something special while having some fun. How do you approach the creative process with regards to collaboration? What are your goals for a session? Describe your method/process for writing tunes, by yourself and/or with others.
