One of the great jazz bassists of our time explores important musical ideas for all serious players. His three essential elements - the physical, the mental, and the intuitive - form the complete process of creating music on the bass. Gary analyzes his improvisational approach, imparting numerous ideas for hearing intervals, intuiting tonal relationships, and how making a "mental map" of a piece provides an understanding of its harmonic construction. This mainstay of contemporary jazz shares invaluable technical and improvisational ideas he has gleaned during the course of his 45-year career. Includes either a booklet or PDF file on the disc. 75 min.
