Sounds like a plan Kasperow! Just like everything else with guitar, the more you do it, the better you'll get at it. And the better you get at it, you can start to do it in real time and play what you hear in your head. That's the holy grail! Perhaps I'll get there one day myself :-).

Back when I was your age (God I sound old!! - it wasn't all that long ago...) we either had to buy tab books, learn from another player, or learn it by ear. We'd mash the rewind button on a tape player to keep repeating a section to get a part down or record a portion of a song 10 times in a row on a tape. Oh, the good o'le days :-). There was no slowing things down or a/b repeat.

BTW, did you have that performance you were building the setlist for yet? How did it go if you did?
