Rolf Sturm's MAJOR METHOD Volume 1 teaches all of the scales needed to solo through any playing situation. This is by far the FASTEST way to learn the entire neck of the guitar! No more blind spots on the neck. Once you know the major scale, you've got the key to almost all of the other scales. The Major Method shows you how. Jazz guitarist JOHN ABERCROMBIE says: It will have you improvising before you can say Dorian Mode!!
