(Berklee Guide). The purpose of this book is to explore the relationship between jazz harmony and improvisation by studying the vertical structures of chords and their function in a progression, and the horizontal or linear application of harmony to melodic improvisation. Each topic is accompanied by musical examples that are designed to help you hear the connection between harmony and melody and to develop a more melodic and creative way of thinking about improvising over chord progressions. The price of this book includes access to audio demos online, for download or streaming, using the unique code in each edition. The audio files include PLAYBACK+, a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right. | Jazz Improvisation for Guitar by Garrison Fewell, Book & Toy | Indigo Chapters
