Does anyone here have experience with those Perfect Pitch/David Burge Courses advertised in Bass Player, etc.? You know, the ones where you can learn to hear "colors" of pitches? Are they hokum or do they really work? Sol Fege is a drag so I was wondering... Sorry if this has been posted in the past. I'm running out the door to do a session and was hoping for some answers by the time I get back... Thanks, Jim T.
