If you are playing Rock music and would like to start learning for insets Jazz or Blues (or any other Genre)
The first thing you should start with is listening!
If you are not familiar with the genre ,playing it correctly will almost be impossible.
Explore and try to find artists and songs that you like.
Now these days you have youtube which is great to explore music.
I remember my seff as a teenager …had to buy cassettes and try to guess by the cover if it will be good or not.
..ah this generation!
