I've been working through Mel Bay's Note Reaing Exercises for Bass (Pacman's suggestion; Thanks!), and I'm running into a question of hand position. Is it best to keep one finger per fret, and move the entire hand to the next position (5th fret) when the music starts moving up, or just go with what feels more natural (I mostly use my index and pinky and not much middle or ring finger)? I tune in 5ths (CGDA), and my hands aren't very big, so I'm having to do some jumps to reach certain notes. Any thoughts?
