I never thought of simplifying a complicated progression to solo over and then adding the changes back in after the fact. What a super cool concept. It might be common for a jazz guy, but as a classical nerd I've never thought to do that. It makes perfect sense as a tool. Thanks for all the great information. You explains things so well. A little fast on first watching but this video is here to study. Thanks. ❤

[@tuomas3964]

The chords at the end of Herbie Hancocks "Tell Me A Bed Time Story" also feature this phenomenon. Bmaj7 Gmaj7 Emaj7 Cmaj7. If one thinks B to be I then its: I of Bmajor, I of Gmajor, IV of Bmajor and IV of Gmajor. So the major chords are forming a stucture that switches between tonalities in a chromatic mediant realitonship.

[@nohjoh08]

Check out the visualization of the fretboard with the 7 3 nps and 5 traditional caged shapes with negative harmony in mind. (This does not work for the 7 Berekely major scale shapes.) D Dorian is in the center. That Berkeley Ionian shape is semtrical (w the repeated g note) All the shapes mirror each other on both sides of that! D Dorian 3 nps is B locrian 3nps (upside down) E phrygian 3 nps is A aeolian 3nps upside down) F Lydian 3 nps shape is literally Lydian upside down. Etc mix shape/phry shape, aeol shape/ dor shape, loc 3nps/ion 3nps. So negative harmony in Dorian is as simple as playing it upside down and backwards on guitar! I have never seen or heard of the fretboard visualization taught this way. Now that I see it I can't unsee it. Works with the traditional 5 shapes too but not Berkeley scale systems Dorian shape w 2 notes on the a string is locrian shape w 2 notes on the b string upside down. Phrgian shape w 2 notes on the g string is aeolian shape w 2 notes on the d string upside down. Mixolydian w 2 notes on the e string is itself upside down. I'm thinking when playing negative harmony in the other modes its a simple as shifting patterns and playing it upside down and backwards. This is really out in left field! I hope it makes sense! What do you think? Horace kept calling that shape semetrical and I was studying it knowing Dorian is in the center and semetrical and it all hit.

[@jazzwarrior7206]

Cool fun eh? It's worth clarifying, though, that 'negative harmony' is not simply a case of inverting a scale from its tonic to get another one, and using that for alternative chords. As conceived by Ernst Levy (the first to use and explain the term), 'negative harmony' is also about reciprocity of TONAL FUNCTION - meaning the relationships of chords in progressions to a tonic. Although it involves mirror image shapes, and some amount of bi-tonal basis, it is primarily about resolution to a single key centre, through RECIPROCAL FUNCTIONS. Levy's conception of this was very much as an extension to traditional major / minor harmony. The Levy conception also chiefly pits Aeolian against Ionian to achieve those sets of relationships, not Phrygian. If you haven't already, check out his book ( - as opposed to videos of others re-interpreting it). Also, one of the best contemporary jazz exponents of reflexive inversion and 'negative harmony' is alto saxophonist, composer, and theorist, Steve Coleman. His website is full of great theoretical info and examples of applications. Also, a fun fact : There are several types of 'SYMMETRY'. The mirror image type, known as reflexive ('reflective') symmetry is just ONE type. For example, the mere act of transposing any given mode, shape , or line is ALSO 'symmetry', specifically 'translational' symmetry - meaning, it is still the same when 'translated' ('transferred') to another 'position' - in this case, a new pitch. If a rhythm is played at double or half speed, this also produces translational symmetry. The act of isolating the 7 modes of the 'major scale' is a classic case of 'rotational' symmetry - as in, the beginning point (or 'centre') of the scale's structure is shunted along one step, but the mode inherently retains the same interval sequence when 'looped' (ie. continuing beyond the octave). Even with reflexive symmetry, as related to musical pitch, there are two types : reflective inversion, and retrogradation - the first transpires on the level of 'SPACE' (pitch depth & height, being on a 'VERTICAL' axis), the second on the level of 'TIME' ('sequential order' IN time, or in HORIZONTAL, linear 'space'). Therefore it is worth being more specific about what 'symmetrical' is actually referring to, in order to be accurate and avoid confusion, but also to be more consciously aware of the other 'symmetries', since music exhibits them all. There are plenty of articles etc. on the net about this if you're interested - just search "types of symmetry". One last fun fact : The scale known as the 'Major Bebop' scale, or '(Major) Sixth - Diminished (7th)' scale (as per jazz pianist & educator Barry Harris' harmonic conceptions', is also it's own reflection. This is because it is basically the Dorian mode, with TWO centres of reflection - one at the tonic (D for D Dorian), and one at the tonic's tritone (Ab for D Dorian). The self-reflection occurs when the tritone center becomes the tonic (ie. G#/Ab). Pretty cool huh? [ NB : 'Sub-fun fact' : The two notes D & Ab are actually the reflective centres for the piano keyboard in the purely structural sense (regardless of any musical considerations), since D sits in between the pairs of black notes, and Ab is the central black note of each trio of black notes]. Keep having fun with the shapes and symmetry - it's good for us!

[@Chris-w4j]

@@jazzwarrior7206 Waiting to learn something from this... Sub-fun fact, that's new. There it is. I didn't realize the 6th dim scale has 2 reflective points. Cool! My point was, it's alot harder to see the reflection on guitar but it's there. Yes I'm aware of the different types of negative harmony and the confusion to the point I label them mirror harmony, negative harmony and any axis harmony. Thanks for sharing

Are any of the other bebop scales (theres alot) double mirrored like that?

[@ArmoniaAplicada]

Hello, that is called REFLECTING MODES.... The modes have reciprocal structures, when they are inverted they are transformed, that is, the inversion of one turns it into another. If you invert the intervallic structure of the Lydian mode, for example, that is, you begin to build its structure from right to left, the result is the intervallic structure of the Locrian mode, this means that they are reflective. If the intervallic structure of the Ionian mode is inverted, the Phrygian mode is obtained, and if the intervallic structure of the Mixolydian mode is inverted, the Aeolian mode is obtained. The Doric mode is neutral because if it is inverted, the same structure results. Thanks for the video, very interesting.

[@jazzwarrior7206]

The discussion on the reflexive properties of the modes is already covered in Noel's part 1 video, "Why 'Chromatic Mediants' sound so good!" (although still mainly focusing on the Ionian - Phrygian relationship). This video is just a follow up, offering examples which subtly contain these relationships by way of major key centres a major third apart.

[@JDhomieG]

What is the reflection of Dorian?

[@ArmoniaAplicada]

@@JDhomieG Dorian Is neutral... Doesn't have reflection

[@JDhomieG]

@@ArmoniaAplicada aahh I see. Thank you.

[@jazzwarrior7206]

@@JDhomieG It seems you may have gleaned the basic idea regarding Dorian & reflection, however, I would suggest that the statement by ArmoniaApplicada is potentially misleading in its wording. It is NOT so that Dorian "doesn't have reflection". It DOES have A reflection, being ITSELF. 'Neutral' does not convey this idea very clearly either, since it implies 'active' and 'passive' polarities which don't necessarily have any clear meaning or direct application in outlining the reflections. There is ALWAYS a reflection for EVERY interval configuration possible. SOME configurations are their OWN reflection, as is the case with Dorian. Another example, of a self-reflecting configuration is the Aeolian Dominant (= Mixolydian b6) mode, which is the 5th mode (= 4th 'rotation') of the Melodic Minor scale : TTSTSTT. In both cases (Dorian & Aeolian Dominant / Mixolydian b6), there are TWO centres of reflection : (1) At their 'tonic' / root / i ; and, (2) At the TRITONE of/from the tonic ( - which is NOT present as a note in the scale, and is therefore a 'ghost' centre). [ Note : Some centres of reflection may be a 'note' (pitch-class), and some may be an interval BETWEEN two notes]. Certain scales, essentially those identified by French composer Olivier Messian as 'Modes of Limited Transposition', have, not only inherent self-reflexive symmetry, but also exact repetitions of particular modal interval sequences, although, at different transpositions / on different tonics. This means they can only be transposed a limited number of times before repeating the exact same pitch content. [ Please note : I can acertain that ArmoniaAplicada understands the situation with these scale reflections, but I don't see that they have conveyed the information accurately to you. Nevertheless, the 'neutral' idea may have caused you to see the inherent self-reflection for yourself. Hopefully, I have clarified the details a little better for you. - All the best studying these properties. ]

I find myself doing this. The changing of tonal center is as good as playing outside in it's ability to alter the tonal center and shift the musicality.

Love harmony sudoku. One of my fave reflections (flippenings) is harmonic major (ionian b6) to phrygian dominant. A harmonic major already has F lydian #2 so it gives you 2 major 7's a major third apart. Reflecting gives you A phrygian dominant or Bb lydian #2 so you get some nice shifting major 7 sounds in there. Also, this reflection can sound pretty subtle since A ionian and A phrygian only have 3 common tones (A,D,E 1,4 and 5) but A harmonic major and A phrygian dominant have 5 common tones (A,C#,D,E,F 1,3,4,5,b6). An easy way to remember the reflected modes is to see that for the major scale the mode pairs always add up to 4 mod 7 (1,3) (2,2) (5,6) (4,7). For melodic minor the pairs add up to 3 mod 7 (1,2) (3,7) (4,6) (5,5). And my fave, harmonic major/minor the pairs add up to 6 mod 7 (1,5) (2,4) (3,3) (6,7) but one is from the major harmonic and the other is from the minor harmonic since this is a chiral scale. Keep on flippen.

[@jacklutz588]

What is a chiral scale and how did you go about learning this stuf?

[@xy-st9dz]

@@jacklutz588 Chiral means a reflection can not create a rotation. Think of an isocoles triangle. If you flip a copy of it over you can rotate it to lie exactly on top of the original copy. A scalene triangle flipped over will never lie exactly on top of its original. This is due to an axis of reflection which allows a symmetry. A major scale has an axis of reflection (think of the dorian mode which is a palindrome), this means any rotation (mode) can be achieved by reflection or rotation. By contrast, the harmonic minor scale has no axis of symmetry and therefore its reflection will never equal a rotation or mode of the harmonic minor scale. It's reflection is called the harmonic major scale. In chemistry or math this is sometimes referred to as "handedness", i.e. left hand/right hand. As for how I learned this stuff, it involved a pen, a pad of paper and many hours sitting in a hard chair mapping out as much as I could. Then a few years learning every mode of every scale all over the neck. It wasn't easy but worthwhile things seldom are.

[@JoaoLouro-i9n]

Exploring Ian Ring's scales site, it seems that those more "pointy" scales/modes you mention have really fun "flippenings": Harmonic Minor Mixolydian b2 Harmonic Major Phrygian Dominant Dorian b2 Melodic Minor Lydian Dominant Half-diminished etc Also really curious about how the "demented" concept you touched upon on a previous video might relate to this, as it appears to relate harmonic major and minor scales by a minor third apart. I suppose the chromatic mediant thing might have to do with how an octave divides exactly by either 3 augmented (maj 3rds) or 4 diminished (min 3rds) triads?

Using the tonic as the reflection point we get phrygian. Use the fifth instead, we get aeolian. Negative harmony generally refers to this aeolian case. We might think of Ab and Eb as cousin keys to C. Parallel transformation by Major thirds or minor thirds.

[@sixmillionaccountssilenced6721]

As far as I know you can use this with all modes though. Borrowing chords from all C parallel modes. C phryg, C lyd, C mixo, C dori... so in the end C is related to more than just Ab and Eb...

You do end up with chords built from the major scale on the flat 6. That's not the whole deal though. Its not straight transposition. Reflect the intervals down. C two tones up to E, then a tone and a half up to G gives us a C major triad. C DOWN two tones to Ab then two more to F gives an F minor triad. For D minor, D is a tone above C, so we start a tone below on Bb. Then a minor third down G, and anothe major third down to Eb. D minor triad flips to Eb major triad.

What you described is natural harmony Lyd/dor Ion/aeol Mix/phry Negative harmony with axis on the interval aka mirror harmony. the intervals are the same in both directions. Lyd/loc Ion/phry Mix/aeol Dor/dor If you use the axis between the root and 5th on the circle of 5ths the negative pairs are: Lyd/phry Ion/aeol Mix/dor Loc pairs with loc next key over. There is also an any axis or movable axis negative harmony theory where you can move the axis anywhere between the intervals or on the intervals to harmonize with all 12 keys.
