Tony, The job of the bass player is to know the chords. Some of the best musicians are bass players because of knowing chord structure as the basics of playing bass in the first place. Along with the chords you have to know the scales that fit the chords. However, playing do, re, me, fa, so, la, ti, do on every chord will only make you sound like an idiot. Ha ha! It ver simple but oh so complicated.

I said this before. The telephone uses 10 digits to make millions of millions if not trillions of trillions of phone numbers. A horn has 12 notes between octaves. Add to this the way the note is attacked, the volume, the tonguing, slurring, lipping along with the fingering tricks, and different octaves and you get infinity. All of you science students here should really appreciate this opportunity to do so much with so little, eh?
