Wait, why am I trying to be funny in these headings? (reasoning)

So, User:IlL Inthar had decided to make the idea of dipentatonic scales, and I had the idea of maybe slamming some cool permutation thingies onto these things.

For context, a dipentatonic scale is "a 10-note scale where every other note gives an MOS pentatonic scale generated by a diatonic-sized fifth (between the 7edo fifth and the 5edo fifth) of a fixed size." What I plan to do is to find all the different pentatonics within these 10-note scales and give light directions as to where this can go.

If you couldn't tell, all of these scales are in 27EDO.

The best part about this specific way of making the graph is that you can slap two different dipentatonic scales into either of these and combine them to get interesting scales.

For example, taking the 38th row for the 2nd scale and the 24th row for the 3rd scale & combining them, we get a nonatonic scale. Taking the 19th row for the 1st scale and the 56th row for the 4th scale and combining them gives you another nonatonic scale. Pretty neat! (though the 2nd scale could probably do better with a different mode, but hey)

You can already imagine about the modes of these pentatonic scales, including all the scales that could be made from combining them and the modes within. I don't know how many scales you can make from this, but I can only imagine its a lot. I imagine a bigger graph can be made for finding the modes of each of the dipentatonic scales to possibly find more pentatonics from it. I might actually do that soon.

Its crazy what simple things can do to a scale.
