Is there a learning path for a semi beginner level I can follow? I thought there are some backing tracks, but are there any work sheets or practice exercises ?
Start with Tyler's beginner videos and take some of the techniques he's talking about and practice those. Even within each video are smaller exercises to practice. Pay attention to what he's doing and then try to replicate that on your instrument. If you're able to progress with his videos, then you're on the right practice routine.
I'm a fairly disorganized person, What works for me right now is picking an area of focus, this month it's technique, next month I'll choose something else :)
