"So far so good, you can run through the double stops as an exercise.
This is a great reference book!"
Tim S. from Schenectady, NY
Some of the best material out there is made by non-professionals. Chris does have a degree in music but it seems that he wanted to write down this double stop stuff, which is useful in all kinds of music. And he did the world a favor!
(I wrote out one double stop chord progression in C major and was just starting on modal 'double stops'. So he saved me a ton of work.) Thanks Chris.Doug C.
