Marion, I've been thinking about this one for the day. The parrt that interested me was wanting to know how theory relates to playing. The way I would try to connect those two would be to take three very different songs and their accompianments(sp?), sit down with pencil and paper and figure out the relationships between every note in the accompianment and the melody etc. Then I'd start trying to compose or create my own accompianments based on what I'd figured out.
