A scale reference for Locrian Scale box shapes (the 7th mode of the Major Scale). These are the five shapes/patterns for the Locrian scale on guitar:
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.
I hope you have found this useful, let me know in the comments :)
