I'm tackling my first solo for bass guitar piece. Victor Wooten's Amazing Grace arrangement, and thought id start a discussion on how to go about learning new music.

starting with the basics, I identify the key and chord structure. then i try a unrehearsed run through of the piece to see if i can play it.(usually i cannot)

from there i will break it down to one measure at a time (one note if i have to) and progress to phrase, finally ill start adding the phrases together until i can play the whole thing.
