I have a hard time memorizing a lot repertoire. I play rock, mostly classic and pop rock 60's to current. Mostly covers. It's not that I can't remember the chord progressions, or the solos, or the parts. I can remember the individual sections quite easily. It's that I get the changes/transitions from section to section wrong too often. Do we do one more verse or is the solo now? That sorta thing. Repetition isn't the answer for me, because I don't have the time to drill 100 or so songs over and over. It isn't efficient. I need to devise some kind of system for this to solve this problem. Perhaps remembering keywords in the lyrics for the transition points. Does anyone have any tricks, or tips, or techniques for memorizing the structures of songs that you know all the parts of, but need to focus on where the structural changes are (verse/chorus/solo/break/outro/etc.)?
