Acknowledgement: A John Coltrane Legacy is a historical approach to the music and life of John Coltrane. It includes interviews from other jazz musicians who played with him.
It has a detailed analysis of each of the Coltrane Tenor solos: Two Bass Hit, Ruby My Dear and Acknowledgement. The latter has a special feature called The Inverted Fourth Principle. It was used exclusively in Coltrane's "avante-garde" music. Nothing is said of The Inverted Fourth in any other jazz publication that I know. The book is a very exciting and informative read for anyone. Especially the jazz enthusiast.
