The whole clinic is available at Casa Valdez, a great jazz blog and is worth listening to for any type of musician, no matter what your instrument. Scofield presents a lot of very clear ideas on how he approaches learning tunes and music in general.
This particular part jumped out at me because I think about how to practice all the time and have often wondered about the practice routines of musicians I admire.
I'll let Sco lay it out:
All the musicians I know, what they're about is learning how to learn...and getting good at learning and to keep that happening...to keep learning...keep absorbing music and learn how to learn something so that it comes back through you. Learn what to learn in your practice time—what to work on. You get better at that. So you don't have to play arpeggios for an hour, scales for an hour and then get to the real thing...to weed out the unimportant things you work on and to really work out, up here what it's going to take to improve. So you got to keep your wits about you in this practicing thing.Later I'll post an analysis and transcription of his improvisation on Stella by Starlight and how he goes about getting the tune under his fingers. It's a killer.
