The BGIS Lesson Book features a step by step explanation of the most essential melodic, harmonic, & rhythmic elements that make up the bebop idiom, coupled with 27 jazz etudes demonstrating their application in order of gradual difficulty.ABOUT THE SERIES: Developed over a 10 year period by its author and used as an instructional method in various music schools, The Bebop Guitar Improv Series consists of two volumes with downloadable multi-media materials. It is intended as a guide to lead both the player with little or no formal improvisation skills, as well as the player who does so exclusively by ear, on the journey to becoming a seasoned jazz improviser. Each volume is comprised of 3 books: the Lesson Book, Workbook, and Scale & Arpeggio Fingerings guide.Volume 1 is devoted to using the blues tonality as the primary vehicle to teach the rudimentary principles of jazz improvisation in theory and practice. Structured with the novice improviser in mind, it initially focuses on learning how to systematically develop a vocabulary to improvise over chord changes from a guitar-oriented technical perspective. Four varieties of 12 bar blues are covered in order of difficulty:1. Traditional Blues (I-IV-V),2. Jazz Blues (with II-V cadences),3. Minor Blues4. Bird Blues (Charlie Parker style).Each new progression is taught throughout a series of etudes, and gradually introduces one or more of the chord/scales required to improvise over most jazz standards.Various melodic concepts and syncopated rhythms commonly used in the swing/bebop idioms, are taught as well.Volume 2 builds on the principles explored in Volume 1 and explores various applications over "Rhythm Changes," as well as major, minor and extended tonalities. The technical focus is on multi-positional playing using the entire fretboard.For more info please visit http: //bebopguitar.richiezellon.com
