Learning Tunes on Casa Valdez Blog

There's a great jazz blog over at Casa Valdez, and the other day I posted a question about learning tunes:

I picked up an Aebersold book at the last IAJE called "How to Learn Tunes". Frankly, I wished there was more meat to it, but the basic gist is, memorize repertoire via categorization. In other words, make lists of tunes you know (or want to learn) grouped by characteristics such as key, meter, tempo, form, type of melody and harmony, rhythm/groove. This is something you can do while traveling or away from your instrument.Another good technique is to work with a metronome and practice the rhythms of a piece. My question lately is, what sort of mnemonic aids do other musicians use? I generally write lyrics over and over by hand to learn them (I'm a singer). But since I don't accompany myself on stage, I find that when I learn a tune on the piano, after the initial process of reading it and learning it, I forget the names of many of the chord changes. In other words, I have the muscle memory in my fingers but intellectually I rarely retain the names of the chord changes. Any suggestions on improving this, or on learning tunes in general?

The comments from the other readers are invaluable. I'm definitely going to print some out and apply them.
