Book excerpt: The "Exploring" series of books within the Harmonica Masterclass Lesson Series walks you through each of the most commonly played positions on the ten hole diatonic harmonica. This book and recording for 3rd position focuses on the basic principles of what makes 3rd Position work, scales that help maneuverability and speed within 3rd Position, and interactive jamming with David Barrett and the David Barrett Blues Band. This volume contains the most extensive catalog of 3rd Position blues licks and phrases ever written. You will not only learn the common minor form of soloing in 3rd Position, but the less well-known major soloing like that of the great George "Harmonica" Smith. If you are looking to dig deep into the usage of advanced tongue blocking techniques, this will also be a great study for you; many of the songs in this set use tongue blocking and as a focal point. If you are also looking to get into blues chromatic playing, this book is a great primer. Playing blues chromatic is identical in movement, technique, and breath patterns to 3rd Position playing on the diatonic. Written in notation and harmonica tablature. Includes access to online audio.
