I'm writing a piece where I have a rhythm bass going, and the lead bass comes in and takes over, but following the same progressions, and I'm starting to have all these questions. 1) When you look at a tab, and it says E5 at the top, does this mean the notes being used are E and B? Makes sense, for powerchords or whatever. 2) So I was going to start writing the lead bass lines, and the first section was in the key of A. How many A scales are there? Is it just Aelion *sp*, or whatever the mode for A is? That can't be right, I'm confused over here, lol. Any help is mucho appreciado. I printed Chapter 2 of Wheats bassbook, if anybody wants to use that as a reference. I also have Chuck Rainey's "Guide to Electric Bass" or something, but I hate that book. He doesn't explain anything. 3) This one should go in Technique, I'll just stick in here for personal ease of reading. How do you play artificial harmonics at the 24th fret?
