This is from my Lesson of the Week segment of the site. The idea of Extension and Contraction is so common for the left hand but rarely practiced in the right hand. I’m using Exercise 21 from Ricardo Iznaola’s Kitharologus: The Path to Virtuosity (Amazon). This book starts off super easy but gets gradually more difficult (to high…high levels). However, I love how sequential and progressive the book is, it’s probably the best book I’ve seen for guitar. Just don’t get your hopes up about finishing the book because it truly for those in it for the long run. You can find more free lessons at the lesson archive page.
