@Bellyman interesting comments! I don't play jazz, so the ideas of "driving," "train wreck," and "pushing to failure" are all new to me.
Bellyman Step 1, then step 2, and then (if you take it), step 3.
So step 2 is playing for others, and step 3 is playing with others?
That's interesting because I would put it in the reverse order. Step 1 is playing alone, step 2 is playing with others, step 3 is playing for others (whether you're playing on your own or with others in that step 3 part).
Back to the original question, "why perform for others" .... We were at brunch today, on campus. The place has a grand piano and there's always someone playing, with a tip jar out. I'm pretty sure it's always a student from the music school at the uni where I work.
Anyway, I found myself thinking I would love to do that. I currently have about 45 minutes of music ready to go. I could sit there and play, just for one set. I don't care about (or need!) the tips. I would give all the tips to the servers -- or the pianist whose spot I took.
But as I realized I was thinking that, it brought me back to this thread.... where above I believe I said I don't have a "need" to perform.... But I obviously have a pretty strong desire to do so!
I still don't really know why though....
