Jazz has evolved its own harmony apart from other genres of music. In order to improvise and compose in the idiom, a basic understanding of this harmony---how chords move and connect with each other---is essential. In this book, noted author and educator Dan Haerle explains all the fundamental chord/scale theory and harmony you need to know. At the end of the book are voicings to over 20 standard chord progressions so that you can clearly see and hear how the various rules apply in real-world situations. Written for all musicians. No keyboard skills are required, but knowing the names of the notes on a keyboard will be helpful. 88 pages.
