The Essential Guitar Patterns That All the Pros Know and Use. Accomplished rock guitarists can ad lib hot solos and play backup in any key, all over the fretboard. There are moveable patterns that make this easy to do. You need these fretboard roadmaps if: all your soloing sounds the same; some keys are harder to play in than others; your fretboard beyond the 5th fret is mysterious, uncharted territory; you can't automatically play any familiar melody; you know a lot of bits and pieces on the guitar, but you don't have a system that ties it all together. This book/CD pack will help you learn all this and more until you're playing like a pro! The CD includes 39 full-demo tracks.
