(Book). This book by versatile trumpet player and composer Randy Sandke is divided into three parts. In Part One, he identifies and organizes all four-note chords which lie beyond the tonal system and cannot be represented by conventional chord systems.
Part Two deals with deriving melodic material from these metatonal chords, and in Part Three, Sandke shows how he has used these ideas in his own music, with example pieces included for symphony orchestra and jazz quintet. “A fresh, creative approach to improvisation … Highly recommended.” Michael Brecker
