Uncle Tim's Building Blocks: A Visual Guide to Diatonic and Pentatonic Scales: A Complete Guide to Understanding Diatonic and Pentatonic Keys

Summary: This isn't the fun stuff, but it'll get you there.
Review: I learned long ago that putting in the work up front will pay off later. Scales now will mean great playing later.

So when I wanted to pick my guitar back up after a few years, I went looking for something that didn't sugar coat the whole process with some sort of easily palatable, faux music theory.

This book lays out the Major and Pentatonic scales in a comprehensive, easily absorbed way. Having everything laid out in a visual form makes the learning curve easier.
