A scale reference sheet for Major Blues Scale box shapes. These are the five shapes/patterns for the Major Blues scale on guitar, based off the CAGED System:
1 (E Shape)
2 (D Shape)
3 (C Shape
4 (A Shape)
5 (G Shape)
Pick a key.
Locate the note on a string.
Overlay the pattern with the 'R' falling on the note of a chosen key.
Play pattern up and down then pick another key.
Practice ONE shape a day and spend 2mins learning the pattern and moving it around to different keys.
