This volume investigates the systematic construction and application of hexatonic scales to expand the harmonic vocabulary of improvisers and composers. Jerry Bergonzi, a renowned jazz educator and saxophonist, provides a technical framework for utilizing six-note scales to achieve a contemporary sound. The text focuses on the practical implementation of these scales through triad stacking and melodic line construction, offering a methodology applicable to all instruments.

This work is regarded as a technical resource for intermediate to advanced musicians seeking to modernize their harmonic language. The material provides a rigorous, pedagogical approach to scale construction that is highly valued within jazz education circles.
