For instance Bmaj7-->Cmaj7 ... Sounds pretty old school if you do it in a certain way! And this sub came to me by way of Barry Harris.
There's limits to this - you aren't going to get away with playing super intervallically all the time on a New Orleans style gig... but you can do it a bit... Can be fun, see what you get away with.
In fact vertical restrictions on chords I would say is more a characteristic of the more modern players. Chords = colours, more. One way to sound modern is actually to banish tritones from your lines, which gets rid of a lot of the functionality. So don't play dom7, m6, m7b5 and o7 sounds...
For instance focus on major and minor triads or pentatonics and superimpose them on the chords.
So
G7alt becomes Eb/G, Ab/G, Db/G, Db major pentatonic, and so on. This has the effect of creating a colour on that chord, removing it from the realm of voice leading.
Chord scales broken up into fifths, that kind of thing. Consonant colour tonality. This is something I hear a lot in Lage Lund's playing. Diatonic sevenths and seconds can also be repurposed into semi consonances... For instance, this chord feels non resolving and static:
x 7 x 5 3 7
You can also weaken its functional effect by turning it into a compound interval (#11)
x 3 x 2 3 2
This is a fun thing to drop into traditional styles. This idea was not in fact alien to people like Django... He played a lot of triads and even major pentatonics, so you get some interesting superposition. Simple example, very stylistic is the Bb triad on E7 (minor swing.) Lage Lund said he really liked Django's playing, interestingly... I'm interested in making the connection in my own playing.
You can combine this with the motion approach and have a lot of different vibes you can create....Last edited by christianm77; 04-28-2020 at 08:52 AM.

Abm7 Db7 is a ii-V.
So Db7 is the V...
Of course you could also play the I which is Gbmaj7... Now that could be fun Gbmaj7-->Cmaj7.

So might be a good time for a recap... what theoretical concepts were using and why and how etc...
1) tri-tone subs... pretty easy, right. invert or flip the tri-tone of Dom. chord and we have another dominant chord.
key of "C"... G7 is the V7 chord. Invert the tri-tone, "B" and "F", the 3rd and b7th of G7... to become "F" and "B" , the 3rd and b7th of Db7. The Tri-tone sub of G7 is Db7.
That "Sub" source doesn't need to have a Tonal Reference.... a Key is not required etc... the extensions can be established by a number of organizational methods.
2) "Relative" subs are another source... the basic reference is "Relative Minor. Again pretty easy, the "Relative Minor of "Cmaj" is "Amin" and visa versa, the "Relative Maj." of "Amin" is "Cmaj".
This "Sub" source does require a Tonal Reference, a "Key", and has implied extensions.
3) "Chord Patterns" subs are also a source for "Subs". The most common Jazz "Chord Pattern" is the "II-7 V7".
II V's imply "Tonal References". All "Chord Patterns" have Tonal References".
The somewhat bonus of "Chord Patterns" is that they have expanded possibilities of implied "Tonal References". By that I mean.. Chord Patterns can Have different "Tonal Targets".
Ex. That "II V" can Have as a Tonal Reference or Target of... The II-, the V7 or the implied "I" chord.
D-7 G7 ... the Tonal Reference can be,
1) D-7
2) G7
3) Cmaj7 or the implied target of the "Chord Pattern"
So where I'm going is when you use Subs... there is a difference between... "composing" or creating music, and using sub's for improv or soloing.
When your composing your using Subs to help organized structural aspects of the composition. But when your soloing.... there all ready is an structural organization.... "the Tune" in place. There are already Tonal References.
And when you begin to "Expand and mix and match" subs sources and principles. It get Muddy.
As in the thought process of using Tri-tone sub organization to get a new Dom. chord... then adding the II- chord and thinking and using that II-7 chord as a "Relative" relationship. Which has Tonal Relationships... the implied Imaj7 chord.
My point again is.... if your "Composing" there isn't as many Tonal References... as when playing or soloing over implied Tonal References. The mixing and matching of "Subs" with different organizations of Tonal References, takes practice... Some work and some don't, and for reasons.
The expanding of "Relative" through the use of "Modal" organization is complicated.
Ex. So .... / D-7 G7 / Cmaj7 /
becomes / D-7 Db7/ Cmaj7 / If you add the Ab-7 to the Db7.... it's not really the "Related II-7 ". We just use the Term because of Habit. If it were really the "Related" II- of Db7.... we would be Implying the Tonal Reference of "Gbmaj".
Which we're not. The Db7 has the tonal Reference of "Cmaj". So the "Ab-7" is really just part of the "Chord Pattern" .
Again if your using Ab-7 Db7... you would use it in the same Harmonic Rhythm as the "Db7", the Ab-7 isn't subbing or replacing the "D-7".
The chord progression or solo practice would be.... D-7 (Ab-7 Db7) / Cmaj7 /
Again the Ab-7 isn't the "Relative" II-7 of Db7, at least when your soloing, comping etc...
If your using the "Relative" approach your actually changing the implied Music.
Expanding basic musical concepts, like "Subs" with the use of "Modal" organization gets complicated.
Yea the other Door, or "Functional" expanded organization, cool, I've been pushing that approach for 40 years.

Excellent and timely recap, Reg!

Actually lately I think more and more that a melody played with conviction can turn anything into relationship...
Most of of the truths we believe in after all are just the matter of conviction... if you repeat something to people fast enough and intensive enough without letting them think twice - they will accept it (Hollywood proves that)))
I am much about harmony as basis but the more you get solid into it the more you feel how the melody (set of melodies maybe) is basically all what's left
Maybe it sounds strange but some point I feel like I begin to stick to that ambiguity that melody provides more than anything else.. (geeting old?)
(disclaimer:When I say melody it is not necessarily catchy pop tune of course)

I'd like to understand this material better than I do.
To start, can someone explain exactly what the quote above means?

Hey RP... maybe.... the source or mechanical organization of Tri-Tone subs is just that. The organization of creating Db7 as Sub for G7 is mechanical. The Db7 is a Tri-tone sub of G7 in any key or any Tonal context.
There is no Tonal reference implied. It will work in almost any tonal context.
As compared to Diatonic Subs, or Relative and parallel subs. They have Diatonic Tonal references.
When we bring in Modal references, we're expanding the possible results, but they still have tonal references.
As with almost anything, there are always exception, but in general.

now of course on the face of it you may ask...ok..how do you use that info ..(this hit me with ... WAY too much info to process..)
in a harmonic sense it would require some attention to the overall harmonic / tonal structure
in a melodic sense it would have to align with some of the melodic direction of the tune
in a improvisational sense..you can throw away most of the rules and try and tread water as best you can..
its the circle with a circle routine..the further OUT you go the closer to Home you are ...unless you bring it to a dead stop and start over or go on a sheets of sound rant
Its nice to see/hear the familier safe side of improv..but when your playing without a net and making it up as you go there is little time or care for what may be around the next turn ..
wrong notes have been left far behind and no one is really counting anywayLast edited by wolflen; 04-28-2020 at 09:44 PM.

You just need to know how to resolve. Really then you can do anything then, go in and out of key, it doesn’t matter.

An interesting obvious observation I embarrassingly made
only in the last few years:
The chord tones of any given 7th chord will never be mathematically further than a whole step from a nearest chord tone move to any other
7th chord. Therefore, from a close voice leading perspective,
it is physically possible for any 7th chord to progress to any
other 7th chord with minimal movement.
Ex. Gbma7 Cma7
Gb Bb Db F > G B C E
or
Gb Bb Db F > E B C G
-
However, some hit the sweet spot of having enough different notes and not too many common tones to give that sense of satisfying cadence.
Gbmaj7 -> Cmaj7
Gb Bb Db F
G B C E
Definitely true of this one!
not so much
E7–> Cmaj7
E G# B D
E G B C
Generally cadences with the most semitone moves sound most satisfying.
Consider this then:
C D E G A - c major pentatonic... in chordal form a C6/9 chord
Now, what notes are we left with?
Db Eb F Gb Ab Bb B
Db—>C or D
Eb—>D orE
F—>E
Gb—>G
Ab—>G or A
Bb—>A
B—>C
And what’s that scale?
-
E7–> Cmaj7
E G# B D
E G B C
Better:
E G# B D > E G A D
or
E G# B D > E G C D
etc.
