The basic idea is this. Say you have a ii-V in C.
- First you learn how every note in C Major (D dorian if you want to think about it from the ii chord, whatever easier) voiceleads to Ab melodic minor. You can also think of it as G altered, or Db lydian b7. Doesn't really matter, whatever is easiest for you. I tend to think of it as Db7 because it's the tritone sub and Dm7 - Db7 - Cmaj is easy.
- then you learn how to voice lead every note from Abmm back to C major
- the other crucial thing is that he basically views G half whole diminished as a variation of the altered scale. You choose one vs the other because of the sound, the voice leading makes sense, etc. Use your ears. By the time you start adding chromatic approaches, the line between the two gets very blurred.
Practice this until your ears/fingers just automatically hear where to go.
I want to emphasize: this is really not a bebop sound. This is very much a Bill Evans and his followers sound. If you want a bebop sound, listen to Barry Harris (and Christian).

A lot of my "altered" language is just HW Dim, sometimes against a chord with the b13. I still don't understand why I ( think I ) get away with it. Tone deafness maybe.

I force myself to play things on the gig instead of trying for a flow state. I’ll leave that for the second decade.

I found that some stuck in my brain better than others.
My current goal is to get the 7 voicings (starting with stacked 4ths) memorized in order, so I can make a melody with the top notes while playing the chords. 12+keys and no thought. Work in progress.
Getting that down, along with already having the same sort of thing for major and relative minor, means that I can easily find ways to move the harmony on every beat, if desired, for most chords.
And, I've also found another approach based on the chord patterns that Reg talks about, if I understand him correctly. I can't get it from the verbal description so readily, but Reg has lots of lesson videos posted on youtube (Reg523) where you can hear and see exactly what he's doing on a number of tunes. He gets a very classic kind of jazz harmony sound (to my ear) for comping.

From what I got from Reg you basically stop thinking about chords all the time and Autumn leaves
goes from
|C- F7 |Bb Eb |A-7b5 D7 |G-6 |
to
|C- | with | movement to | G-6 |

Better to start with one head in one key right?

Interesting. What I gathered was not about leaving chords out, but adding more in. And, time feel.

Dm7=Fmaj7=G7=Am7=Bm7b5. Also all interchangeable.
Am7 is in both Types. But, I usually think of it as relating to Cmaj,
2. Start with xx7788 (C69) and move it through the Cmajor scale. That leads to 4 grips to make seven chords. I use them all more or less interchangeably in C tonal center. To make that work you have to keep them moving or the avoid notes will take over. This is not theoretically precise. It may require some adjustment by ear.
3. Well maybe another. I do use tritone subs.
I just watched Reg's How High The Moon video. What he does is real substitution, to my way of thinking. So, for 8 beats of Gmaj, he'll put in a quick D7#9, and back to Gmaj. It's often workable to throw in the dominant in that sort of situation. That usage is not predicted by my approach, as stated above. Then, for Gm7, he uses several different voicings, including C9sus C7b13 and Gb13. That's more consistent with the stuff above.
I wouldn't say that any chord consistent with this theory will work. And, it might be better to get this stuff from transcribing rather than theoretical journeys. Maybe pick the top 50 jazz standards and work through the various devices on record. Or, start with one A section of one tune.
Caveat: I don't recommend my approach. I don't insist that everyone else make the same mistakes I do. I think like many, players, it was built haphazardly over time based on what I was exposed to and what I could and couldn't do.
-
That’s the opposite of what I meant. I probably took too much liberty with simplifying the concept.

My point, which may have been rooted in a misunderstanding is that Reg doesn't trace a path from a starting chord to a target two bars later without regard to the chords in the middle. When he does it, to my ear, you hear the original harmony, but jazzier.

what I think of as Bill Evans era devices have a sneaky way of showing up a good decade earlier.
Billy Strayhorn is a huge figure. But there’s other things.
Shearing’s conception has the locrian #2 expressed via an Amaj#5 arp against Ebm7b5 in the first bar. Amusingly, Evans missed out this sound (he plays E and not F) when he played the head of Conception which is funny because I always thought of the m9b5 sound as a real Bill Evans thing.
So going back to dominants the most voice leading one can have in a key is the most ways of voice leading by half step to the I chord. This turns out to not in fact be the G altered scale but the Db mixolydian. But the Db mixolydian is not of itself a harmonic sound built on the G7 as it contains that major seventh on the dominant.
And this makes sense if you look at bop lines this appears to be what’s going on. A Night in Tunisia for example
A very good tune to study the bebop treatments of altered dominants is Hot House. There are many hip devices that perhaps got retroactively incorporated into melodic minor harmony theory later. (Although maybe he was thinking in those terms, Tristano seems to have, so honestly I don’t know) And the tune can be understood in these terms - Tadd Dameron is perhaps unfairly neglected as an important guru figure in bebop.
the contemporary way of handling the altered scale eliminates a lot of the dissonance and focusses on things like major and minor triads and pentatonic scales found within the scale. This has its roots in the bop era, but in general modern chord scale like lines are more colouristic/harmonic and less hungry for resolution than bop lines.
(I post this here in case anyone is interested in this concept.)
Really, a lot of what people call modern post modal jazz harmony is what Herbie Hancock played on Wayne tunes haha. This makes sense as modern jazz theory was invented by piano players.
Wayne Shorter for his part seemed to almost perversely avoid the altered scale even where it would seem a very obvious choice, his solo on ESP for instance has no use of this scale and of the Wayne solos I’ve looked at the scale doesn’t surface at all - he seems to have preferred chromatic and symmetrical scale options, including Monk’s favourite the whole tone.
Both Wayne and McCoy tended to play half-whole, as of course did Trane.
The post bop era is very diverse in terms of approach.
Now everyone is taught the same ‘go
to’s so it’s more samey.

It took me about a decade to realise that despite the chord scale talk, Reg is a subs guy

The Nunes things you cite are like rules of thumb. The Levine Theory book is more, well, theoretical.
Either way, they have to be practiced. Whether or not you see playing an Abm chord on G7 as a manifestation of the Galtered scale or just a rule of thumb that sounds good, you have to practice seeing dominants in all twelve keys and playing the minor a half step up. I do wonder if that’s a mistake people make - I know I tended to overvalue the theoretical framework rather than the really important thing which is the specific practice.
My assumption is the historical way is more that people learned these things as rules of thumb and less as manifestations of underlying chord scales. (Also some classic subs are not understandable in a vertical way. D7#9 on G is what I think of as movement or functional sub.)

My understanding of this sort of thing—not related to Reg—is that simplifying changes almost always enables me to play more stuff, rather than less.
Caveat is that you have to know the purpose of the chords you’re playing.
If youre in Rhythm Changes in Bb, then those turnaround chords can really be anything that gets you from one Bb to the next and all the movement you do will be color and tension and it’s extremely liberating not being bound to specific chords, two to a bar, at an up tempo, so probably you play more than you would’ve otherwise played.
If you’re in the first eight of Stella that’s a very different way of getting to Bb and you’d need to be a bit more specific … though you could unclutter some of those secondary cadences
-
I feel like this is almost certainly true … you’ll hear things like a C#o over an F7 or an Ebm over an Eo in a four and back … and those are things that can’t really be made to make sense in a strictly theoretical, chord plus chord equals big chord sort of way

“Chord plus chord equals big chord” that’s basically modern jazz theory in a sentence haha. Maybe “Chord plus chord equals big chord that can be tidied up into a scale and given a clever sounding name”
