(Evans Piano Education). Scales have long been considered an essential element of keyboard mastery. They provide piano students the technical skill needed to play the instrument and give practical instruction in the basics of music theory. Jazz Piano Scales and Exercises presents a novel and more interesting way to practice patterns and etudes while learning jazz. Following the notation and fingerings for scales major, harmonic minor, and melodic minor in each of the 12 keys, three jazz exercises are given. These serve to reinforce the patterns and fingers and to give the player a sense of the melodies, rhythms, and harmonies that are integral to jazz stylings.
