Here's the deal with Lisa ... she's awesome, and her choice of songs has a purpose. Specifically, she's trying to get you used to making the changes in the easiest way possible. By doing so, musical concepts and muscle memory are reinforced. Yeah, some of the tunes may be boring but, in the end, they are easy to play and build confidence. Trust me, you'll be glad you participated in this rudimentary, but necessary exercise. Lisa really knows her stuff.
