Watch the G# Locrian online guitar lesson by Robbie Calvo from Power Concepts
In this Power Concepts lesson, you'll be applying the E major pentatonic scale over a G# Locrian chord progression. A G# Locrian progression is created by using chords derived from the A major scale, however the progression will resolve to the VII minor7 (b5) chord, G#mi7(b5).
Why am I using the E major pentatonic scale instead of G# minor pentatonic? Well, G# minor pentatonic would be derived from the F#, E, or B major scales and therefore would contain notes that would not fit at all over our progression built from the A major scale. Analyzing one chord is fine, but in a progression, you have to consider all of the other chords too.
In chord substitution, the VII chord and V chord are substitutions, so I’m advocating you use the chord sub pentatonic as well so that we can stay truly pentatonic as per my concept. Take a listen and I think you'll agree it works nicely. Try using G# minor pentatonic and you'll hear what I mean about the outside notes.
