i've been trying to become a better guitarist to jam with, so yesterday i was playing around with the ii-V-I progression when i happened upon a sound that i've always wanted to figure out but never spent time to figure out deliberately. my ears know it as a chord substitution used to end a jazz song...i think i first heard it on a Barney Kessel track, but i don't remember which.

anyway, i want to know if there's any interesting theory to know about it, or if it has a name.

Dm7 - G7 - G#-6/9 (??)

in case i got the chord names wrong, here's what i was playing:


----------------------------------------------------------
----8---6-----5---3--------4---------------------------
----5---------4------------3----------------------------
----7---------3------------3----------------------------
----5----------------------------------------------------
--------------3------------4---------------------------

It's Ab 6/9, not G#.

That's just a bVI chord, a common deceptive resolution. I wouldn't necessarily call it a sub for I, but it can certainly replace the I chord.

The reason I wouldn't necessarily call it a sub is because it will throw off the soloist, most subs are not something the soloist has to listen intently for to avoid playing, well, badly.

thanks! not exactly a sub, makes sense to me.

i'm familiar with the concept of deceptive cadences, but since this one goes outside of C major i was wondering if there's something else going on that i could explore further.
