"When you hit a wrong note, it's the next note that determines if it's good or bad." —Miles
Presented without comment, because to even try would be to miss the point.
I had to learn "Halleluja I Love Her So" by Ray Charles for a gig I had awhile back. Normally when I learn a tune and it comes to the solo, I like to improvise my own. But I always check out the original to see if there's anything I like, or even better, something I should steal.
