A quick overlook on progressive guitar chords and jazz to get the player started. Just browsing the book will enlighten you. The book will discuss the 5 basic 7th chords that are a must to know for jazz and progressive guitar. It also discusses the arpeggios for each chord. The book will also give you the chords to a given key (a must) and two types of cycle of 5ths which are found in most jazz standards (another must). This book gets right to the point there is not a lot of explaining. After 33 years of teaching most people don't want to hear a lot of rhetoric if this is how you feel then this book is for you.
