Backdoor dominant resolution

[CliffR]

Any advice on ideas to try for voice leading from a backdoor dominant to the root? Oh, I see 5th off the dominant to 3rd of the root works. And 7th to 5th. I probably should have looked more closely before asking.

Suppose C7b9 going to D minor with a back door movement. C7b9 scale is identical to A7b9b13 (just superimpose them, you'll see). What that means is you can use all your voice leading ideas from A7alt -> D in the context of C7b9 -> D movement.

Another way to see this is that the C dominant scale with a b9 is the D harmonic minor scale, the dominant in the D harmonic minor is A7b9b13.

Well they taught us in school that notes like to resolve up a half step or 4th, and down a whole step or 5th. So those are the legit rules I believe. But you can also just experiment and see what you come up with for your guitar voicings. It's an alteration so doesn't need some formal rule.

In practice that chord often has a sharp 11 ...

So you get ...

Bb D F Ab C E

Play around with the little group of Ab D E resolving to G C E.

Or just Fm going to C.

My best advice is to strum the chords and scat sing. When you sing something you like, put it on the guitar.

But, for the math ...

Bb7 is Bb D F Ab and extends to C, G. I'll omit the 11th for this post. Bb13.

Cmaj is D E G A B C (omitting the 11 - it's a C69maj7).

Notes in common: D G C.
Gravity (not an "official" word for it): Ab probably wants to resolve to G. F to E. Bb to C (or maybe B).

So, if you want to generate a line from rules, have it include some or all of D G C. And, then have the Gravity notes move accordingly. So, you have a line that includes, say, D G C F against Bb7 and then some or all of D G C E against Cmaj. So, notes in common and one note F to E, moving for the voice leading.

This is just an example to illustrate a way to think about it, not specific lines.

I would say

5th off the dominant to 3rd of the root works. And 7th to 5th.

Mostly the later

That's also Valt - I. One reason the BD dom works.

Thanks all for the great ideas.

Are you sure?

Nope, I mixed something up. I now have 2 chord licks to suggest.

Why are you calling people female over a benign discussion? lol What are you?

It's part of the lyric to a song called Back Door Man.

I knew it would end up being contextual.

By the way, the backdoor dominant chord often resolves to the wang dang doodle chord, is that correct?

No, you're thinking of the black cat bone, I believe.

Koko Taylor agrees..
