I'm new to this group, so i have a few questions to ask. first, I am reading Alain Danielou's "Music of India." Do most of you consider the traditional 5 limit ratios to be authentic, or do some beleive in a more partchian 11 or 13 limit approximation? Is the source code for scala available? Does anyone follow the Schlesinger/modal/arithmetical proportion line of folk ratios and Ancient Greek music? I have already built a few Ancient Greek instruments, but now I plan to cosntruct a Kithara (not a Partch giant) which includes a modal fretboard capable of playing all the Ancient Harmoniai. It would be nice to speak to someone about Arithmetical proportion possibilities.
