How long is a piece of string? You need to learn MUSIC nor bass guitar, that is all. I was thinking about this the other day when I saw a book called Scales for Bass Guitar (or something to that effect). Whatever scales exist, exist for every instrument not just one
You may not live near a college that offers bass guitar studies but I guarantee you will live near a pianist who can point you in the right direction. Where are you based? That may help people on here guide you. Obviously you need to apply your learning to bass but the let the music guide you. As for Tal, she ios a cool player but not really advanced in any sense. I play regularly with musicians that leave me open-mouthed with how good they are and I ma gradually being dragged along in their slipstream. It's the music that does it, not the instrument. Find some musicians that take you places you may not otherwise go. Talk to pianists, guitarists, sax players etc NOT bass guitarists. They are mostly full of s***
PS I haven't played with Tal, obviously, but I have done a gig with Jason Rebello, his keyboard player. A great experience and I learned a lot.
