Book recommendation for non-beginner

I like Harmony & Theory, published by Hal Leonard. I bought this years ago, but I already understood the basics of standard notation, keys, and modes. Whether it's a good fit for you depends on where you're starting from. Where are you in this process?

Go to Amazon and call up these names:

• Ed Friedland - Has a knack for putting words together so we understand what he is saying. He introduced me to scale degree numbers, i.e. R-3-5-7 and after that I understood what I needed to do.
• Ed Fuqua - His book, The Fundamentals of Jazz Bass Playing needs to be in everyone's library.
• Roy Vogts - One of the Masters. And he has just split his offerings into three separate books which has lowered the price to where it is now well within range of we mortals. Check out his offerings.

All three of them are TB members and do chime in when they have time.

 

Funkifying The Clave- Lincoln Goines/Robbie Ammeen

...should be available at Amazon.
Bought mine years with cassettes (blech)...current version has cds. On sale for around $19.
I see there is also a DVD, too.

 

It's a $25 investment. Pick one and get started.

They all cover the same stuff.

• Scales to get your fingers moving. You will not be running scales in the songs you will be playing. Yes you will be using scale notes, but, not in scale order.
• Chord tones (R-3-5-7 & 8 of the chords scale) for your bass lines. Non-chord tones (2, 4 & 6) add color. Most time roots, fives and eights do 80% of the bass lines we end up using. The jazz guys get into the 3 & 7 plus 9, 11 & 13.
• Modes are for your lead break solos. Each mode has a mood. Pick the mood you want your solo to give, then play the mode that gives that mood. Guitar guys get off on modes and, IMO, it's best to let them do the modes. Because of our low frequencies they do a better job of this.
• Then on top of all that is rhythm and groove, that part of all this that most often falls between the chairs.

Each book mentioned will touch on these things, pick one and get started. You will end up with most of them sooner or later.

 

You have a good base. If you want to learn how to use chord tones, I recommend Building Walking Bass Lines by Ed Friedland.
Building Walking Bass Lines (Bass Builders): Ed Friedland: 8601400675656: Amazon.com: Books
Actually, I recommend anything by Ed.

 

Depends on what your goals are and what problems you have with technique. Everyone has a limitation on what they can do. Any further advancement will come at a great cost in time and effort. In other words, once you reach a level, to get better will take exponentially more time and effort. Everyone has a different peak level.

Thus, if you don't know what your technique problem is, you seek out the best bassist you can find, and ask them. If you are looking for guidance to enhance what you already have, consider, learning another style of music or learning another instrument. Or, consider learning how to do home digital recording. This will open up a world of music so you can apply your bass skills to many other styles of music. And ultimately create your own music.

 

Get Janek Gwizdala's "All the Good Stuff". He's a master at delving deep into really interesting, and melodic, intervalic playing.

I like this one

 

Pfeiffer's book you mentioned is very good for what it does. Speaking of toher methods t owork on your chord tones and fingerboard knowledge, I might suggest the walking bass book of MIke Downes

 

If you are just getting into Jazz in general "The Tony Grey Bass Academy" book is really in depth.
