Super Ultra Hyper Mega Meta Scales

Super Ultra Hyper Mega Meta Lydian (or just Metalydian for short), is simply a repeating pentachord consisting of four repeating intervals: WWWH-WWWH-WWWH etc. The first two iterations happen to reproduce the seven degrees of the Lydian scale before diverging on the #8.

When the diatonic scales first were introduced as "church modes," they were created by stacking a tetrachord on top of a pentachord to get the different 'authentic' modes. For example, the Lydian mode had a FGABC pentachord on bottom, followed by CDEF tetrachord on top to complete the mode's range or ambitus. But in the plagal Hypolydian mode, the CDEF tetrachord was placed below the FGABC, even though the note F was still treated as the tonic. Modes weren't formulated in terms of whole and half steps like the modern scales, though. Everything was thought of in discreet pitches; D for Dorian/Hypodorian, E for Phrygian/Hypophrygian, etc.

"Metascales" are NOT scales. You can't get a diatonic scale pattern to repeat ad infinitum, by adding fifths to fifths or fourths to fourths - these patterns will get out of phase with the octave quickly. But you can reproduce at least the first 7 notes of a scale through repeating fourths or fifths.

As we mentioned above, WWWH is the pentachord that Jacob Collier used in his S.U.H.M.M. Lydian metascale. If we instead use WWHW, we get an Ionian metascale that reproduces the first 10 degrees of the Ionian scale pattern. The WHWW creates Dorian up to its 9th. And HWWW gives us Phrygian, through the 8th degree.

But if we instead combine two tetrachords, we get the first 7 degrees of the other three modes: WWH for Mixolydian, WHW for Aeolian, and HWW for Locrian. So all the diatonic scales can be represented, for at least 7 notes, by repeating patterns of either 4 or 5.

One final point: All the metascales based on fifths tend to become brighter as you continue up through the octaves. Metascales built on fourths, become darker in tonality as you ascend.

I agree with Nick Grooves that Slonimsky's Thesaurus is a great source of information for this exact thing. Slonimsky called it the Disjunct Lydian Polytetrachord. It is disjunct because the Lydian tetrachord (starting in C) (C D E F#) then starts its tetrachord repeat (disjunctly) on the NEXT note of its (C) Lydian scale, which is G, (giving the G Lydian tetrachord of G A B C#), then repeats the tetrachord (disjunctly) starting on the next note of G Lydian, being D (giving D E F# G#) etc. etc. This is Jacob's SUHMM Lydian scale/sound. Slonimsky comments that counting repeated notes in different octaves, this type of scale may have as many as 48 functionally different notes. Conversely, a conjunct polytetrachord starts its new tetrachord ON the last note of the previous tetrachord, i.e. a Conjuct Major Polytetrachord is C D E F then repeat the major tetrachord from the F (giving F G A Bb) then repeat it from Bb etc. I do feel that the SUHMM is not a particularly new concept, and I would definitely recommend Slonimsky's Thesaurus for further study, however, if you want to hear it actually used in an absolutely beautiful and original way, then Jacob Collier is the man. I'm a massive admirer of this guy and think his compositions, arrangements and realisation of this kind of theory is one of the best things to happen in music in a long long time.

An interesting feature of Collier's Super...Scale is that there is a half-step between each segment. That is, the final pitch in one segment can serve as the leading tone to the next. That makes for very smooth harmonic shifts.

Compare that with some of the "circle of fourths" patterns presented by jdjazz. When the transition is upward (e.g., C-D-E-, F-G-A-, etc.), the connecting notes form a half step. But when the transitions are downward (e.g., C-D-E-G-, F-G-A-C, etc.) the connecting notes form whole steps.

It calls to mind the logic behind the melodic minor scale: leading tones are desirable when ascending, but less so when descending.

The feature isn't a necessity. One could build a "circle of fourths" variant of Collier's scale, in which the connecting notes form descending half steps:

C-D-E-F#-, F-G-A-B-, Bb-C-D-E, ...

But the harmonic transitions don't work as smoothly.

If you go around the circle of 4ths starting with locrian you get loc, phry, aeol, dor, mix, ion, lyd. Then if you keep going you get the 5 hyper modes. (Modes that don't contain the root.) Personally I think it's just a scale that modulates through the hyper modes.

In addition to NickGroove's outstanding answer, this technique is used in jazz to "go out" (depart from the written chords) when improvising. Consider this pattern:

C-D-E-  F-G-A-  B♭-C-D-  E♭-F-G-  A♭-B♭-C- ...

When "going out," it's more common to hear a pattern move around the circle of 4ths than around the circle of 5ths. Sequencing a 3-note scalar pattern can achieve that. If we allow ourselves to use non-scale steps, then we can sequence more complex patterns. Here's a very common one (1-2-3-5):

C-D-E-G-  F-G-A-C-  B♭-C-D-F-  E♭-F-G-♭-  A♭-B♭-C-E♭ ...
[CMaj]    [FMaj]    [B♭Maj]    [E♭Maj]    [A♭Maj]

Jazz musicians apply the same technique to pentatonic scales, too. Consider this Cmin pentatonic pattern:

B♭-C-E♭-F-  E♭-F-G-B♭-  G-B♭-C-E♭-  C-E♭-F-G-  F-G-B♭-C

Now compare to this version, where we sequence around the circle of fourths:

B♭-C-E♭-F-  E♭-F-A♭-B♭-  A♭-B♭-D♭-E♭-  D♭-E♭-G♭-A♭- ...
[Cmin]     [Fmin]       [B♭min]      [E♭min]

Another very common variant is to combine ascending movement with descending movement:

C-D-E-G-   F-E-D-C-  B♭-C-D-F-  E♭-D-C-B♭-  A♭-B♭-C-E♭-  D♭-C-B♭-A♭...
[CMaj]     [FMaj]    [B♭Maj]    [E♭Maj]     [A♭Maj]     [D♭Maj]

What you're describing already exists. It is known as the Circle of 5ths (or 4ths if you go the other way). The regular diatonic major scale (Ionian) is symmetrical. Repeating symmetry; two identical tetrachords separated by a whole step between (w-w-h-w-w-w-h). Not "asymmetric chunks." Once you realize this and learn to think of scales this way, you will realize that all major scales can be linked / overlapped around the Circle of 5ths by their tetrachords. The second half of each major scale is the first half of the next and therefore you could link them all saying the pattern "repeats indefinitely" yadda yadda:

C-D-E-F … G-A-B-C … D-E-F#-G … A-B-C#-D … E-F#-G#-A … B-C#-D#-E … F#-G#-A#-B

(C Maj …… G Maj ……… D Maj …..… A Maj ……… E Maj ……… B Maj …… … F# Maj ……)

All Jacob did was apply this repeating symmetry to the first half of Lydian mode. It can be done with any interval pattern, as the OP has already demonstrated.

Read Nicolas Slonimsky's Thesaurus of Scales and Melodic Patterns. It's a much better resource - sorry, a very thorough and creative resource - for scales and improvisation concepts.
