Watch the Key of F: 2 Octave Workout online guitar lesson by Fareed Haque from Modal Improv Survival Guide
A slow play along of the 2 octave F scale, all modes and positions. You can build your F scales from scratch OR Try building your F scale/mode fingerings by taking your C scales and flatting the Bs to Bbs. The idea here and throughout this approach is to always build from what you know, so scales, keys, modes are all builty one form the other, and all are thus connected together. We don't learn 1000 different scales; we learn ONE and adjust it to build all the other scales, one at a time.
