I am self-learned amateur guitar player and I play for quite long time (around 10 years) and not playing jazz/blues bad but I feel not progressing for a very long time.
The reason is that I have no idea about theory of music like intervals, chord progressions etc.
My question is : How to enter to jazz theory ? Because there are lots of sources that are not accessible for me. Where can I start learning jazz theory by myself ?
