I said it depends on which other modes (ήχοι) collaborate. Everything has been saved in oral tradition. No conservatory explains with accurately this and all other major things about parallage (παραλλαγή). Nobody has noticed this flexibility of legetos but me. This approach is mine according my reaserch. I say it is true becouse it is functionable to me and to my students. Thus you can chant anything, no more spooky melodies!Does anyone know the history behind legetos and how or when it changed? Do conservatories address the situation at all when they teach legetos? We have clear recordings from this century (see earlier posts) so it's not clear to me how the tradition diverged. How common is the larger interval legetos versus the smaller interval legetos in Greece?
