This module was a long time in the making. I felt a need to come up with a method to help blues guitarists, like myself understand soloing over chord changes. We are always thinking 12 bar blues. This is a more detailed module on some standard 32 bar progressions that we should know and how to create solos. I use a couple tunes covered by Jimmie Rivers as examples. If you bought my second jump blues module, and Rhy. changes lesson this is the next step.
