Principle #4: Any Dom Can Become a ii-V
This is one of the coolest ideas we have. Now that we have all these dominant chords in our arrangement, we can start to turn them all into ii-Vs. So, C7 becomes Gm-C7. F7 becomes Cm-F7, G7 becomes Am - D7. Basically, each dominant chord we use in our arrangement pretends to be a V chord, and now we're simply adding in the ii to that V.
Let's take a minute and talk about ii- V's. If you've gone through my Jazz Comping Survival Guide
, you may already be hip to some of this. Go back to that course and check it out, but here's the short version: One of the most common chord progressions in all of Western music is the suspension.
That's when the 4th of a chord moves to the 3rd of a chord. C to B in a G chord for example (see chart). A ii-V is actually a just a jazzed-up version of a suspension. In the key of C, the ii is Dm7 and the V is G7. If you notice the motion of the guide tones (3 and 7, remember?) you'll notice that the guide tones of Dm7 are C and F, and the guide tones of G7 are B and F. So, the only thing that really changes in a ii-V are the root moving and the 7th of the Dm going to the 3rd of G7, or
a C going to a B. Just like our classic old suspension.
