Thanks for the article!

yeah... what's the genus (janya) for a raga is not always very clear/in contention. Some double count it, others are stricter as to what is the parent. And for some, it is hard to assign just one parent, since many compositions/ideas for them have come from both the supposed parent (for eg., major pentatonic Mohanam can be both Ionian (Shankarabharanam) and Lydian (Kalyani)).

The graha/sruti bedham group theory is definitely one of my favorite parts to emerge from the classification structure... including for example (I am using western mode names here) the most common western modes, Ionian-Lydian-Phrygian-Aeolian-Dorian-Mixolydian forming a cyclic group.

And then there are a few which are total isolates. So what do category theory people call such structures, where some elements from subgroups, and some don't. Groupoids? Magma?

I have wanted to build this into an illustrative chart for a long time, but never managed to (more like lazy).
