I tried an experiment with one bit that was troubling me. Instead of trying to memorize it, I memorized the type of chord the notes form. So now when I'm trying to recall that bit, I'm always able to do so because I can replay the chord in my mind.
This type of learning aid will hopefully improve my ability to recall other things (such as tcpdump features asked for in interview questions). At the very least, they'll improve my ability to memorize music.
