Thanks Lev! It fits in with what I am trying to master. I want to add knowledge of the modes (not only pentatonic) to that concept. I will also have to master some more phrases and licks to use that concept very well.
EDIT: When I worked on "Gravity" with my instructor, he also pointed out after listening closely that many of the lines were played on one or two strings, rather than in a box or scale, which accounts for the sound of it. Kinda cool, and a good way to be expressive. :)
