Why do jazz methods focus on one's eyes and analytical brain instead of one's ear?
The purpose of this book is to help you improvise better and more naturally by building the connection between your mind’s ear and your instrument.
You have music inside you. You occasionally get excited imagining great melodies and rhythms, but you are frustrated over your difficulty to get that music out of your instrument. If that feels familiar, this book is for you. If you use it well it can help you reduce and maybe even remove that nasty filter living between your musical mind and your instrument.
By stretching your harmonic ear in the way this book will guide you, your instrument will more easily reflect the music trying to make its way out of your creative imagination.
