Par BARRETT DAVID. This is the companion video to the Basic Blues Harmonica Method (book/cd set sold separately as item 99103BCD). As many techniques are much better demonstrated in video format, you will find this video to be a great learning tool. With large charts, diagrams, and many playing examples, nothing is left to the imagination.
