This book is meant to give you a jump-start in playing blues harmonica. You will find there are both easy and difficult techniques on the harmonica.-� Due to the nature and length of this book, and to avoid repetition of sections of other books by the same author- some of the more commonplace blues harmonica techniques are avoided here. A 10-hole D harmonica is required to begin this book, but a Lee Oskar natural minor harmonica in the key of A minor is also recommended. All tunes and exercises in this book are written in standard notation with harmonica blow/draw indications. Although this is not a beginner''s book, the audio download available online provides an additional assist to players at all level.
