Re: Notating 240 < 12n < 312 EDOs

I notice you struggling with the perennial problem of aligning the symbols with their degree numbers on the line below. You've found that the [_]pre] tag helps by giving us fixed width digits and spaces, but the Sagittal "smilies" (small images rather than characters in a font) aren't mono...

Re: Notating 240 < 12n < 312 EDOs

Thanks for explaining how they can't always be consistent with all 12n subsets. I'm glad the closest-to-default rule results in consistency with the smaller subset in both cases. Thanks for those sequences. Another option, that would reduce the cognitive load, but would only work for even n , i.e. 2...

Re: Notating 240 < 12n < 312 EDOs

Thanks! That makes sense. Are the capture-zone boundaries and the default tone-fraction the same as the symbl boundary and the common tone fraction defined here ? Yes, they are. Although I should have said "semitone fraction" rather than "tone fraction". If so, there is one issu...

Re: Notating 240 < 12n < 312 EDOs

Just out of curiosity, how would one notate EDOs that are small enough so that 12edo's fifth is still the best fifth they have, suggesting a 12EDO-Relative notation, but have too many steps to the semitone for the Trojan set to be able to distinguish between all of them, namely 252edo, 264edo, 276e...

Re: Using the Trojan system to notate rank-3 Marvel

I'm sorry I have too many other things going on, to really follow this. I've never found I needed more than 72-edo notation for Marvel. And 240edo doesn't seem like a particularly good tuning of either 7-limit or 11-limit Marvel, relative to its complexity. Yes, if you prefer to completely avoid 11-...

Re: Notating 5-limit pental with added 7th harmonics

Yes. The only-3's-tempered size has some relevance here because you have generators that are fifths (or their octave equivalent or inversion). I overstated the case when I wrote that the untempered size was irrelevant. At least the relative untempered sizes of the symbols are important. We try to av...

Re: Notating 5-limit pental with added 7th harmonics

I note that 255/244 is strictly called the 25/7- kleisma in the systematic comma naming scheme used in the Sagittal documentation. The 25/7- comma would be larger by a Pythagorean comma . Interesting. The interval I chose to notate for 25/7 is actually smaller than the pythagorean comma by a pythag...

Re: Notating 5-limit pental with added 7th harmonics

I don't think it's necessary (or possible) to distinguish a notation for hemipental (if that's what I was giving) from a notation for pental-plus-pure-7ths. You just have to say precisely what the 7-limit symbols represent in each case. This is basic to Sagittal. It's designed so the meaning of symb...
