In the 1990's, I would play notes from a 'Dorian b5' or 'Mixolydian b9' scale over a minor iiV.
(Yes, just altering one note of the scales that I already knew very well.)
Later, I found that these scales were known as the 2nd and 5th modes of the Harmonic Major scale.
Harmonic Major 2nd mode
Dorian b5 over a Dm7b5
D-E-F-G-Ab-B-C
Harmonic Major 5th mode
Mixolydian b9 over a G7b9
G-Ab-B-C-D-E-F
I've been playing these scales today over a minor iiV, and, if I'm selective with the note choices, musically they work very well, if a bit vanilla.
I'm wondering why are they are not taught very often?Last edited by GuyBoden; 04-07-2024 at 07:14 AM.

I think probably because the major 3 is in there. So for Dm7b5 and G7 they both contain the E.
Thats just not a common sound over the minor ii V.
I transcribed a bit of Kreisberg on Night and Day and he kind of uses it … though he avoids the E natural over the actual ii-V for the most part anyway

I'm a fan of weird flatted note scales. I like the subtle dim chromaticism.

I think Monder has a flat 2 lydian that he plays in one of his vids. I experiment with it over altered dominants and mixed with diminished scales..nice and crunchy

I think I use it, but come to it from thinking G7b9 scale -- and recognizing that the C is an eyebrow raising note (back to my theory about hexatonics). And, in a 7b9 situation, the #9 is likely to sound good -- and if you use it, you're back to the 8 notes of the diminished scale.
So maybe it's not commonly alluded to because the Bb is such a good note that you might as well think diminished?

If it feels right, don't be limited by the scale, use the scale to find the notes that make the music. If you play it with conviction, it's yours. In answer to your question, we're taught rules from people who have their own beliefs about what is proper. We play sounds that we evolve to feel right about. When you discover your own sound, use it. If you had the teacher that taught you about scales as choices, and not rules, consider yourself fortunate and spend your time growing. Make music.

I refer you to the first II V I - Em9b5 A7b13 Dm9(maj7) to my ears - lead line F#-F-E
Actually major II V into minor is pretttttttyyyy common in pre-nerd era jazz. Obviously there's dear old Charlie Christian on I found a new baby, but also the melody of Donna Lee contains an example.
Not to mention the V13b9-->Im sound beloved by Peter Bernstein.
I did an lenghty vid on this a year ago...

A lot of the chord scale stuff is teaching the most common sounds, which hopefully is accompanied by teaching the less common too. If I said you have b9 on the V of minor 90% of the time, I’d probably be right and that would make it an excellent starting assumption. But you also wouldn’t bet your life on 90% — so it’s good to point out Out of Nowhere or Billie’s Bounce straight away too.
Also good to keep the stakes on jazz chord extensions lower than “better your life”, I suppose.
Anyway … I hate all the things you stand for, Christian.

To go back to the original question, "why isn't it taught more often," I think it's simply because a b9 on a dominant chord is probably one of the first extensions a player learns to hear and use, before they ever step out of chord tone/major scale thinking...so why learn a whole new scale for it down the road?

It's baked into the way music education operates. People get told stuff by people who are really great and have worked this stuff out off their own backs, and repeat it because that person is great.
Fair enough, if you apply info you can play great, it's not about being a musicologist or whatever. But I'm quite curious about stuff. And I think you can find new sounds, or old sounds that have passed out of use.
Oe thing that comes up in Barry land is, "oh you should make the first D7 in rhythm changes a minor II V' and I think - what? Really? Lester Young doesn't do that on Lester Leaps In. Neither did Bird always. Bud does it on Celia, say, so it's obviously a thing that was done sometimes and it sounds great, but it's not The Default Way to Play Bebop Rhythm Changes. Barry would obviously have known this, I doubt he said 'should', but now the things he said in class are getting 'modified in the guts of the living' to quote Auden.
People quote Ethan Iverson at you in the same way, and so on. Ethan's knowledge is vast, much greater than mine, but he still says things I know to be incorrect.
I'd rather take the example of these people as inspiration...

As I say - different players do different things. At least they used to.

This obviously shows up in the rep as you say. Another example is East of the Sun. Django tended to opt for the 9 on the VI7 chord when soloing for example. I would even go as far to say that the use of the 7b9 on applied dominants is a big aspect of the bop style (along with the more widespread use of the ii V to dress up V7 chords in the rhythm section)
Then you’ve got the ii chord as ii chord thing, which has a more ambiguous character going on … the E7 with F# in East of the Sun is right before the Am7-Cm change, which sounds/feels like a variation on IV-iv minor so it’s a bit of a different thing than the All of Me example.
Then again … Out of Nowhere doesn’t fit that pattern.
Its almost like knowing the songs is important, or something.
ANYWAY … you’re the worst.

Yeah probably because it depends a lot on the chord coming after. There is that quite common “ii chord as temporary tonic minor” a la All of Me, which tends to get the V7b9.
I'm genuinely asking, because I don't know. I haven't transcribed many solos on All of Me. I would tend to play b9 there myself, but who cares what I do?
IIRC Sarah Vaughan sings a major dominant on that one, but I might be misremembering. I can feel a rabbit hole coming on...

I remember Barry instructing us in class not to worry about that stuff when running scales on Cherokee. Parker plays the Ab dominant scale on the Ab7 chord in his solo on Koko for example.
I'd be interested to know where this comes from, I would imagine it to be more of a post 60s concept.
