The Sagittal forum

I finally got around to writing this up on the xenharmonic wiki, since I use it in a few of my other theory pages there: https://en.xen.wiki/w/Undirected_value

No progress made on the puzzle, but I do have a bunch of links to the Yahoo tuning list archive with relevant information about 29-HTT: https://yahootuninggroupsultimatebackup.github.io/tuning-math/topicId_17512#17512 https://yahootuninggroupsultimatebackup.github.io/makemicromusic/topicId_6820#6964...

Hi Dannyu NDos . Good to see you again here on the forum. Re: notation, I agree with Yahya that the best way for you to notate these pitches would be to use the same notation Sagittal uses for standard tuning (AKA 12 Equal Divisions of the Octave, or 12-EDO), which is equivalent to standard notation...

It looks like one good way to go with this Yer temperament would be a 13-note MV3 scale , a 7L 4M 2s, with the pattern LMLLMLsLMLMLs, where L ≈ 103.4¢, M ≈ 85.9¢, and s ≈ 66.2¢. That gives you a lattice like this: - (-2,2) 11·13·17·19 13·19/11 585.4¢ (-1,2) 13·19   1133.7¢ (0,2) 11·13·19   482.0¢ (1...

It occurred to me this morning, now that I've been studying regular temperament theory for many months, to look into what a temperament that tempers out the commas that figure prominently in Yer would look like. If you temper out only the Blumeyer comma, you get this 2.11.13.17.19 subgroup mapping: ...

@Dave Keenan and @FloraC I have corrected my previous post. Hope I've got it in decent order now. Sorry for goofing up in the first place.

FloraC The Extreme precision level of Sagittal's standard JI notation is modeled after 2460-EDO, which uses the full Olympian symbol set, so the notation for 2460-EDO is just every Olympian symbol in order. Dave has corrected the above crossed-out statements in the next post. Sorry for any confusio...

Ah, I see! Yes, depending on the EDO, and may also represent 25/24. But the primary comma is 2187/2048. Meaning, in the absence of other information, that's what one should assume it represents. Let me know if that raises any other questions.

Hi Dannyu NDos ! Welcome to the Sagittal forum. I hope you can get all the info you need, and have some fun and interesting conversations here. In Sagittal, :#: and :b: are the Pythagorean semitone, 2187/2048. You can find this information, and a lot more, here: https://sagittal.org/Sagittal-SMuFL-M...

And here's the zipped Mac installer equivalent of the previous post.

FYI: I needed to revise the instructions in the OP due to a new error I experienced this time.
