I have been learning about IV minor chords and how to use them in a major key. For example borrowing Abmajor to use as a subdominant in C major. Are there any interesting substitutions you could use to add interest or reharmonize when playing in minor key with a for example a -M7 tonic?
Thanks!

So you're basically just asking about a minor ii-V-i, except you want substitutions. Is that it?
And do you only mean chord substitutions? Or different ways of playing lines over the usual chords?
-
This is how you translate major key into minor key
Take whatever gubbins you have on Dm G7
Dm G7 --> C
Dm G7 --> Am
So now you resolve to A, C or E as opposed to C, E or G
To get the sound of the E7b9, it's good to raise some of the G's to G#'s
Does that make any sense?

The simpleminded might get there by sliding into the G7 from a half step up.
Apply that simple notion to, say, a tune in Cm, and you end up sliding into Cm from a Db-something.
Just one option.

I was going to do one of those video demos but I think words will do here, if you don't mind lots of them.
Working out chord subs isn't that difficult given a modicum of knowledge. It helps to know that a m7b5 is three-chords-in one. Also tritones. Also chromatic moves. Etc.
So:
Bm7b5 - E7(b9) - Am7/Am6...
Well, a 7b9 is practically a diminished chord so that could become
Bm7b5 - Bo - Am7/6.
Tritone the E7 and that becomes
Bm7b5 - Bb7 - Am7/6
Bm7b5 is also Dm6 so any Dm variation (Dm7, Dm9, Dm11) would do
Dm11 - Bo - Am7/6
Dm9 - G#o - Am7/6
A Dm9 is like an FM7 so that would do
FM7 - E7b9 - Am7/6
FM9 - Bb7b5 - Am7/6
Or a Dm could be subbed with a G7
G7 - Bo - Am7/6
G13 - G#o - Am7/6
G13 - E7#9/B - Am7/6
Or put two chords to a bar
F#m7b5/Bb13 - Bm7b5/E7 - Am7/6
And then get chromatic
G7/Gb7 - F7/E7 - Am7/6
And so on... The sky's the limit really (well, not quite). What matters, as always, is the voice leading, so the notes of the chords move nicely into each other.

Just thought of another one. A bit dark but it works okay.
Dm69 - E7b9 - Am/M7
x5345x - 0x313x - x0211x
-
Bm7b5 is also G9
-
I SAID THAT 3 chords in 1 subs Dm and G7 FOR CRYING OUT LOUD
Thank god it's Friday :-)

You didn't quite spell it out though. It was there in your subs.
I mean, basically, there are two categories of chord here, G7 and E7. You have a few options with the second, probably the easiest of which is to just use a G# dim7. Later on you explore tritone/altered tonalities and all that jazz.
The first is a borrowed chord from minor. Rag has already covered 3 of the 4 main options, so I'll just put in here:
Bm7b5 --> Dm --> G7 --> Fmaj7(#11)
You have a bit of latitude with the Dm sound - it could be m6, m7 or m(maj7) or any extension you want. Just general minor.
Fmaj7 can also take a #5
I like F/B as a B7b5 sub BTW.
Now, the other three chords of the key can also be used. Basically you can use any of the chords of the G7 scale, mixolydian, but also lydian dominant.
Am --> Cmaj7 --> Em
These are sounds I am starting to explore now a bit more.

Was that post for me or Babaluma? For him, I think.
He probably knows the 3-in-1 trick, tritones and chromaticism, so that was good enough.
Sure, Bm7b5 can be Dm can be F can be Am. Also F#5. F/B is good too.
E7 can be dim can be Bb7 can be Fm can be G7 can be... etc
CM7 can be Em can be Am can be #11 can be... etc
We still don't know if this is just for chords or lines as well. I suspect chords. Also, is this just hypothetical or is he actually playing something?
But, to repeat for him, voice leading is supremely important. It's all got to connect properly.

Don't overdo Am, BTW. Start by resolving to a triad tone A C E, and then after you get handy with that, introduce the 9th (B), 6th (F#) and major 7th (G#). ("Don't ever play no minor 7th. That ain't no minor." Barry Harris....)Last edited by christianm77; 08-10-2018 at 04:51 PM.

And so on. I'm sure there are countless examples and doubtless the theorists will be along with all sorts of other things which I can't think of at the moment. I mean, take a G7#5 - FBD#G - and it could be an F9b5 without the 3rd... you could go on like that for ages, I suspect.
What I think makes the m7b5/m6/9 special is that all those chords are in the same key (Bm7b5, Dm6, G9). That's slightly different from a combination of notes spelling out other chords that could be in any key.
As for a technical term for two or more chords with shared notes, I've no idea. Which doesn't mean there isn't one.

Well, I was going to emphasise it's all about function rather than 'chord names' but it was covered in one of the links. Possibly by yourself :-)
-
Ah, there you are. Great, it's so nice when someone replies! No problem. I still don't know if there's a technical term for it, though. Never mind
