Olegario Diaz 
Bidirectional Contemporary Jazz Improvisation for All Instruments 

This book is a summary of exercises and jazz improvisation lines designed to improve contemporary jazz style techniques.The book is divided in scale, arpeggios, chromatic exercises and jazz lines phrases from Brecker, Berg, Mintzer, Coltrane, Henderson, etc. These exercises should be transposed to all twelve (12) tones, so we can achieve perfect coordination. Major, minor and dominant chords, extended to their highest level, scale wise, arpeggios and chromatic passages. There are none signature centers, so all these exercises will be worked accidentally. This project is an extension of my last five books of improvisation: * Improvise Now* 240 Chromatic Exercises + 1165 Jazz Lines Phrases* Herbie Hancock The Blue Note Years* John Coltrane & Michael Brecker Legacy* Chris Potter Jazz Styles
