Duarte, John - Melody & Harmony For Guitarists  

The primary aim of this book is to help the reader to understand the language of music and how it works in relation to the guitar. It is not intended as a substitute for all other lines of study, but it will provide a basic knowledge that can be expanded and developed. The reader is urged to read as wide a range of books as possible and to examine whatever music he or she possesses to identify further examples of the points discussed. The examples should be played and carefully listened to.
