When does "exact duplication" end and "creative interpretation" begin, for you?
When you're learning a new song, do you try to learn all the little nuances, changes, and chord substitutions that the original recording uses, and THEN start improvising your own ideas? Or do you implement your own ideas as you go along, like "That turn around isn't necessary, I'll just play it straight" or "Oh... I didn't realize they were playing a C9, not a C7. Oh well, I'll just stick with the C7".
If you learn it one way, then hear the original recording and think "Hey, that way sounds pretty nice, and it gives it more variation" do you go on and add it, or just keep playing it the way you always do?
An aunt and I were learning a song together, listening in the car. I'm accompanying her on guitar. It's a very jazzy/r&b-ish style with the main accompaniment on keyboard and bass, with a lot of subtle chord changes and substitutions. I've memorized the song well enough to where we can perform it without the CD, and I've been playing it all afternoon.
But now that I'm at home to listen to it on my good speakers, I hear a few different bass notes, and some chords that are just a little different than what I was playing, and I can't decide whether to learn all that, or just stick to what's stuck in my head.
What would you do?
