Man, every time I think I'm getting close, Griff throws in another curve ball.
Try relating it to lessons we've already had.
It's similar to the 3rds & 6ths we did a couple of weeks ago.
Instead of 2 notes in double stop 3rds (R-3),
we now have 3 note triads, R-3-5.
The SHR for Major applies to triads and "smaller" double stops, as well as "taller" chords. Just different numbers of notes.
Kind of like triads + or -.
Playing over a C7, Griff suggested "counting from the V",
just like we did with double stops.
This is Mixolydian mode. The only difference from the Major is the b7.
This is actually F Major counting from the V. All the B's are flat.
You could also harmonize C Major using the SHR and go back through and flat all the B's (Bb).
It's easiest for me to just think Mixolydian and flat all the 7's of the Major.
Also, last week we were discussing getting the chords for the A Natural Minor scale by taking the C Major chords and counting from the vi.
Here we are taking the same C Major chords and counting from the V (Mixolydian).
It's interesting that most people understand harmonizing the Major Scale using the SHR.
But when harmonizing other scales things get wonky.
You just do the same thing.
Build triads using the notes of whatever scale you are using.
