John Coltrane's landmark composition "Giant Steps" used a new harmonic formula. This book examines it in detail as well as "Countdown!" Also contains many practice exercises and solo examples, plus how to use this new harmony over standard harmony. This book is an essential companion for these volumes in the Aebersold play-along series: Volume 68: Giant Steps and Volume 75: Countdown to Giant Steps, both available separately. Also available in French and Japanese editions!
