Dear young friend,
You clearly seem to consider I am a square man that is not with it.
At your age, I would probably have the same disrespectiful attitude toward my father generation,due to spirit of youth.
But now I have gained the necessary hindsight and deliver some points to meditate.
Music has to be accessible to a majority of musicians.This is possible thanks to tradition ,e.g a set of rules slowly worked out and adopted by mostly all musicians.It often takes several centuries.Tradition is maintained by teachers,what I did here.
Evolution requires
either slight derivation of etablished rules by rebellious composers(Most of the great composers such Monteverdi,Mozart,Bach)past to posterity.
Or theorist that evolve new theories or experiments such the 31-tone technique you seem to refer to. However despiste a large span in its evolution this technique remains confidential and therefore cannot enter the tradition.
You may notice that very few theorist composers notoriety last more than a fashionable period compare to the rebellious ones
I was born in the Rameau 's country but ,contrary to Germany,his theory was obviously rejected by the way I was teached Harmony 45 years ago. Things seems to change now (250 years later !)
Equal temperament waited for more than 2 centuries to be adopted by nearly all musicians. So be patient!
Our respective errors were to specify what temperament we consider;anyway it has been an interresting controversy
Best regards
Ps (I'm still not sure we were talking the same thing :you mentionned 7th harmonic (no S) I was talking harmonics(or flageolet)a glassy specific tones)
