This book acts as a (somewhat complete) encyclopedia of scalar and tonal resources for the practicing creative guitarist. The book presents every important scale through articles on construction, their use, their history and their relationship to the bigger picture. On a larger scale, the book presents and builds and understanding of a more synthetic, holistic viewpoint of practical tonal organization, or understanding how all this fits into a sense of dark and light. This book is dedicated to the creative guitarist. It is aimed at the person seeking to further develop their understanding of how to use this wonderful instrument to express themselves in their own unique way. It is for the person in the rock band, the singer/songwriter plunking out chords and melodies to go along with their words. It is for the guy out in the garage spending hours on end honing the craft of recording music on his computer. It is for anyone trying to find his or her unique creative voice and express it through the medium of the guitar. This book is aimed at the student who pursues music from a creative viewpoint. It is especially for the person trying to get an overview of tonalities and color-moods available through the organization of these scales. This is an idea book for guitarists. It is an encyclopedia for the practicing guitar enthusiast that will give you a great clue as to the scope of material that can be drawn from scales. Scales are some of the most basic building blocks music is based on. Guitarists at any level of understanding will gain insight from the material here, even if only to look up a few common scales to play some lead solo work with. The real value lies in the overview it gives of the whole chroma of tonal colors available to the guitarists, and where all of these actually lie on the instrument. The Scale Book was written because a big empty place exists in the educational material that portrays this kind of creative thinking. You could spend a small fortune in tuition and rent, move to Boston and go to a fancy private college and study guitar and music theory for years while they trickle it out over years and years. I wrote it in an attempt to fill the gaps in the information available to the student of creative guitar who is seeking to tune-in to their own unique creative voices. There is a lot of information here. Hopefully, the sheer volume of all that's here will not overwhelm the mindful student. Instead, I hope that you will keep a copy of this book around for years to come and refer back to it every now and then to realize how much the material here can transform your playing as the ideas take root in your mind.
