This resource is designed for jazz enthusiasts and musicians who want to have a better understanding of the language of jazz. To successfully navigate this all-in-one jazz theory course, you should be versed in basic music theory concepts, such as those taught in Books 1 and 2 of Alfred's Essentials of Music Theory. With these books, you will learn the essentials of jazz music through concise lessons, practice your jazz music reading and writing skills in the exercises, improve your listening and ear training skills with the CDs, and test your knowledge with the review that completes each unit. You are encouraged to play and/or sing the musical examples throughout, at first with the recording, then on your own. Welcome to an exhilarating journey into the world of jazz!
