Recently, I have been experimenting with musical scales (in 12edo) which are off the beaten path, for my own compositions. My subjective impression from auditioning various scales is that I did not like the sound of two consecutive semitones in ascale. I Googled "consecutive semitone avoidance", and I found the article "Scale Networks and Debussy" by Dmitri Tymoczko:

Soon after, I also found "The Consecutive Semitone Constraint on Scalar Structure: A Link Between Impressionism and Jazz":
http://dmitri.mycpanel.princeton.edu/files/publications/consecutivesemitone.pdf
These articles have a lot to say, but the main observation that I took away from them was that the collection of scales which are used in tonal Western music, from the Renaissance to post-bop jazz, are exactly the scales which have the following two
1) They have no consecutive semitones.
2) Consecutive intervals are either semitones or major seconds.
With those constraints, you obtain all the "church" modes (Ionian through Locrian), the whole-tone scale, the "diminished" scale (alternating m2 and M2), and all the "jazz" modes (ascending melodic minor, etc.). I found that to be highly interesting.
Some additional Google searches have led me to discover a school of thought called "Neo-Riemannian" music theory.the Wikipedia article I referenced, Tymoczko apparently published a criticism of some Neo-Riemanninan ideas, but it seems to me that his criticisms are about some details of the theory and not the general goal.
https://en.wikipedia.org/wiki/Neo-Riemannian_theory
I have barely begun to read about this subject, but I think that what the Neo-Riemannians are trying to develop is an efficient framework which would do for chords and chord progressions what Tymoczko's two rules above does for scales. According to
I never learned to enjoy serial music. The constraints that serialists impose on themselves with 12-tone rows are too tight to allow much in the way of melodies that sound connected, harmonies that sound connected. I love dissonance, cacophony not somuch.
If anyone has any thoughts on Tymoczko, Neo-Riemanninans, or any other systems which encompass post-functional harmony, please share. Thanks!

Hello, and I wish Margo was still around to provide erudite comment.
I've collected a lot of material on tunings, temperament and musical acoustics over the last 20+ years and have come to the conclusion that
for Western music (to include notation, acoustic (non-electronic)
instrument construction and tempo/performance) when all factors are
weighed, there simply is no substitute for 12-TET (or 12 EDO).

You/he seem to be leaving harmonic minor and harmonic major out of your scalar palette and they both have an important role in jazz as well as
in post-tonal classical music.
I understand why scales with consecutive semitones are problematic for extracting harmonies. But an augmented 2nd interval in a scale doesn't usually cause those types of problems. Even the harmonic major scale
yields recognizable tertian triads and 7th chords.

Obviously, I can't speak for Tymoczko, or the thoroughness of his survey of music.
But would you say that you can easily find persistent use of harmonic minor or harmonic major in compositions, in long passages, the same way that you find the other scales he listed? My musical experience says they're used much less commonly, in
will be 12/7 steps, about 1.71. A "maximally-even" collection of seven steps will have two semitone steps and 5 whole tone steps.I understand why scales with consecutive semitones are problematic for
extracting harmonies. But an augmented 2nd interval in a scale doesn't

I agree, that's an interesting harmonic observation. I know that I always found the harmonic minor scale to sound a bit wonky. I haven't tried composing harmonies with it. I've never even tried harmonic major.
Let me make a suggestion then: composers may have found the augmented 2nd / minor 3rd scale step to sound out of place in a heptatonic SCALE, though perhaps it causes no great difficulty with harmonies.
So what is a desirable property for scales, whose job it is to provide horizontal connections, rather than vertical? Some people say that "evenness" is acoustically important. If we're dividing 12 equal semitones into seven steps, the average step
If we require even one minor 3rd in a heptatonic scale, we're forced to change a M2 to a m2 to compensate. We have to push two intervals away from the mean, making one smaller and one larger.possibly be used to explain the observation "church modes first, jazz modes next, and (apropos to you) harmonic minor only occasionally, and other heptatonic combinations even more rarely":
The arrangement of those intervals matters too. If we put two semitones together, it somehow weakens the scale-like properties to many listeners, myself included (see above).
I won't say that I whole-heartedly support every reference that I post, but here's a link to an article, "Circular Distributions and Spectra Variations in Music: How Even Is Even?" It discusses a mathematical definition of evenness which might
http://archive.bridgesmathart.org/2005/bridges2005-255.pdfsimultaneous use of both melody and harmony. That doesn't mean that you can't take something a little off-kilter like harmonic minor, make it work as the centerpiece of a tonal composition, and make it sound great -- it just means you'll have to work
I will propose the following: for a pitch collection to have versatility and wide use in tonal composition, in general, it has to have desirable harmonic AND melodic properties, because the composers of tonal music are generally trying to make
Think about the modern "Berklee School" chord-scale system for jazz: it seeks to map every chord to (generally, familiar) scales which are supersets of its chord tones. The system doesn't get you to everything that sounds harmonic and tonal -- but itgets you quite a lot of it.
https://en.wikipedia.org/wiki/Chord-scale_systembecause of their simultaneous utility as scales and as chord material. It wasn't completely arbitrary.
I don't know this chord-scale system as well as a professional jazz player. But I take the idea behind the system, that "every chord fits into a scale" as implicit support for my proposal that tonal composers settled on the scales in common use
All that being said: you have inadvertently touched on an issue that I might eventually discuss in more depth. In searching for new material, I have stumbled across two observations: one is an eight-note chord, and the other a six-note chord. Both "break the rules" in interesting ways, and yet they're still strongly tonal to my ears. But this post has gone on long enough.
One has to keep in mind that tonality was first defined by melody and not
by harmony
and the harmony was then a result of the combination of multiple melodic lines and a few rather simple use rules derived by what sounded natural to the composer.
The pattern of the I IV V7 I and other cadence formulas came later as composers began to look for ways to add to their musical pallet and the early composers used the harmonic series as a guide. So in order to find tonality don't forget the importance or the melodic lines
