Watch the Key of C: 2 Octave Workout online guitar lesson by Fareed Haque from Modal Improv Survival Guide

that you visualize the fingerings as shapes, notes and intervals…imagine the notes in many different ways with the guitar in hand, and also when the guitar is NA. Sing them, say them, think them, see them. Speed is also important not to impress your friends, but so that you can get these fingerings and fingering shapes into your subconscious. Think it and think it and then DONT THINK it anymore. "Try not, only do"- Yoghurt.
