Thank you very very very much for this post!!!!! You are one more big evidence for what lm saying for ten years now
Well, look. This is the legetos , what you hear in this recording of Stanitsas and Danielides ,the correct pure legetos . This seems weird to you because you have learned another legetos ...
In conservatories and almost all music schools teach wrong legetos.
Many discussions are for this issue in the greek section of this forum , I also have published a lot of my work and research in my blog, look this diagram
here.
Legetos is the ancient hypolydian tone on parypate chord and the indervals are exactly the same as Aristoxenos and all ancient harmony teachers have reported : pa 6 vou 9 ga 15 di 12 ke 6 zo 9 15 pa . This position is the original one , vou a semitone up to pa and vou-di is a major third 24 pieces. In the following diagram you can see the original positions of all the notes including vou:
Check the corrected diagrams of the true intervals based on the ancient Greek music theory by me
here
The ancient teachers called legetos because in paralage ,the way we chant transform those intervals . So the di ga vou is getting different . In plagios 4th the di ga vou is small(12 pieces) in second mode in system of the five the di ga vou is
neutral third (21 pieces)
