How did the ancient Greek concept of tetrachords evolve into the whole- and half-step model familiar today?

  • Do you mean the enharmonic, diatonic and chromatic tetrachord described by Aristoxenos? Or Pythagoras' idea of stacking pure fifths on each other to deduce the 'white keys'-diatonic scales, consisting of two tetrachords per octave

  • @Michel Wait, aren’t they part of the same history. I.e., Pythagoras had his discoveries and Aristoxenus built on those later?

    yes but Aristoxenos talked more about the 'microtuning', with the enharmonic being the most complex tetrachord, containing dieses. And I think Pythagoras did non care about the microtuning, he used the 'bare' tuning which later was named after him (Pythagorean tuning) en.m.wikipedia.org/wiki/Genus_(music)#Enharmonic

  • Throughout history, scales kept getting larger in range (ie. notes were added). Today, each diatonic scale can be thought of as consisting of 2 tetrachords, but the term simply denotes 4 consecutive notes, while I think in ancient Greece, they thought of them as modes. If you think of scales in terms of tetrachords, you can quickly classify them into minor-major, major-minor, minor-harmonic, major-harmonic, minor-melodic, major-melodic, etc. Dec 22, 2023 at 17:13
