The jazz theory book by Mark Levine work through

Very nice book, lot's of concret example. Very well made I bought it over 10 years ago and still serve me well. It all depend what you are looking for.

 

Aunty Eminor???
Seriously - Any serious bassist, (or any improvising musician, for that matter - yes, I'm looking at you too, drummers), should get to, and begin to learn how to operate, a piano. The benefits are too numerous to mention here.
Literally.
IMFNO.

 

@David A. Davis, I think the Jazz Theory Book is a fantastic resource on multiple levels. I've worked through it myself and have found it very helpful, especially Mark's approach to melodic minor. One of these days I'll work through Mark's piano book too!

I'm sure I'm not alone in saying that, should you have any questions about what you're learning, feel free to post them here in this thread and I will try to help.

 

The piano book really won't give you a lot that isn't in the theory book. Both are excellent. My only quibble is that there's really not much on developing melodic ideas or developing rhythmic skills. For that stuff I strongly recommend Mike Longo's stuff, particularly The Improvised Melodic Line.

 

This is THE BOOK as far as I am concerned. The right balance of theoretic and actual working knowledge. I saw Mark play at Cezannes years ago. Good player.

PS..Gotta have a piano to get the max value out of this book.
