But was I born with the ability to play Jazz? No way! I started off in exactly the same situation as you, so I can totally relate to your frustrations...
Forget playing great hard-hitting authentic walking bass lines, I could barely read the chord changes, I kept getting lost in the middle of Jazz tunes. I didn't know what to play to get out of the same few boring patterns. It frustrated the hell out of me. Any of this ringing bells for YOU?
However, after many years of investigating and listening to Jazz records, attending gigs and jam nights and learning from some great teachers, I made a big discovery...
All the great Jazz bass players were using certain musical devices that made their bass lines sound so authentic and convincing and this was probably what got them hired in the first place!
If you are struggling with your own Jazz walking bass lines, can't reach the level that you want to be at and really don't feel like you can freely improvise walking bass lines on the spot from chord charts...
Are you actually ready to DO something about it?
