Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Thanks so much for that. I believe the double-scroll and the triple-scroll look too much alike when on a line. I believe I can improve them without compromising anything else. I should be able to get to it in a few days.

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Yes. Thanks for that. We're definitely getting there. Can you explain why you didn't go with my version of the triple scroll, which has no close approaches between scrolls (more uniform whitespace between them)? Is it because of the middle one getting lost against a staff line? I had hoped that was ...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

I didn't check them against the staff lines. I trusted you to do that, and you didn't disappoint. I think that what this is all trying to tell us, is that we can't get away with a single shape of right scroll for all three cases: single, double and triple. What if the single right scroll for the Sto...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Thanks for that. It's quite different from what I had in mind for the scrolls. Here's what I had in mind. Stoic Sagittal-1.sfd How do your sharps, flats and natural differ from standard ones, apart from not being as wide? In what sense do they form parallel lines with the stoic symbols, that standar...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

That was quick. I agree we don't need another shaft variant, given the way your new right scroll interacts with the shaft. In fact, to be consistent with what you've done for 9, 10, 11, I think we should have the same right slope on the top of any shaft that has any Stoic right scrolls. New list bel...

Re: Simplified "Stoic" Sagittal for 13-limit tonality diamond use

Well done Nick! Before anyone else has a go at it (I agree the Stoic right scrolls can be improved), would you please copy the middle-of-three-right-scroll and the middle-of-three-left-barb to become unencoded components, and include them in all the Stoic symbols by reference only, with appropriate ...

Re: 270edo in athenian+trojan only

As you may know, George and I agreed on the following notation for 183edo: 183: :|(: :~|(: :/|: :|): :|\: :(|(: :/|): :/|\: as given in the Scala file https://sagittal.org/sag_et.par Interestingly :)|(: rates higher than :~|(: , and it has lower fifth-slope too. Why isn't 2\183 :)|(: instead? Good ...

Re: 270edo in athenian+trojan only

I found an email to George in 2014 in which I wrote: "There are also several [EDO notations] that I believe we have agreed on that are not in the XH article or in Scala. These are 270, 282, 306, 311, 342, 388, 494, 612, 2460. These should be added to the Scala sag_et.par file." But we neve...

Re: 270edo in athenian+trojan only

Thanks for those. I haven't had a chance to think deeply about them yet. But here are a few shallow thoughts: I note that the Stein semisharp :>: is available as a forum smiley : >: and the narrow semiflat :<: is : <: . When editing a post, if you click on "View more smilies" you'll see th...
