I decided to put together a new intermediate learning material on how to enlarge your vocabulary in blues beyond the basic blues scale. I have never been satisfied with how harmonica instruction and playing is detached from the world of music. There are many books that do not offer any added value beyond what has been already said zillion times. I hope that this material and approach I chose will aid in the advancement of the instrument. Also, check my other books which cover advanced topics very rare in the world of harmonica teaching. You will find all stuff in the BUY section.
