Re: 13-limit JI

Cam, as you said above, you should use the precise notation with the accents, to be faithful to the composer who does not accept any edo-approximations in notating his music, so he wouldn't approve rational approximations either, no matter how accurate. Again - it's not that he or anyone wants that ...

Re: 13-limit JI

Cam, "I'd agree that any of the Johnston quartets could be potentially very useful. I absolutely love the fugue ("Solemn") in his 10th quartet if you happen to have a copy of any of that?" Great! Good choice. I'll scan it for you. We might also try something very complex (a passa...

Re: 13-limit JI

I can't help thinking that there's an overwhelming number of difficult-to-decipher, difficult-to-write-in-shorthand symbols in the Promethean level and that there's an overwhelming number of symbols to memorize. I'm very uncomfortable with the multitude of commas that one is required to learn (in th...

Re: 13-limit JI

So two steps on the 7-axis would be notated as :|): :|): ? That is, would the accidentals in this system be combined into potentially long horizontal strings of symbols, as in Johnston? What's the recommended accidental for 49 in mixed Sagittal? Thanks for your offer to help with the cello piece. I'...

Re: 13-limit JI

"But you can see that we had a difficult job, to satisfy everyone. Some people say there are too many symbol." I understand this. But instead of the cumbersome clustering of symbols that you find in JI notation systems such as Johnston's there are now all these unique symbols to memorize. ...

Re: 13-limit JI

Hi, "Sabat et al notations don't have a single symbol for 35:36 or any of the other combinations of primes for which Sagittal has single symbols." Johnston has 5-limit nominals, so actually the single symbol for prime 7 is indeed for 35:36 but then 63:64 is notated with a combination of 35...

Re: 13-limit JI

"In that case, I don't understand why you said it "has to be notated as 36:35 up from a flat :/|): :b:"." OK, that was because I assumed understanding the logic of the :(|\: symbol requires familiarity with pure Sagittal - which I don't want to refer to in my scores - but of cour...

Re: 13-limit JI

Hi, thanks! I'll read your explanations carefully and may come back with questions or comments. About the interval notation - "why should a JI major third be notated 4:5 when it forms part of a triad, but 5:4 as a bare dyad or interval?" - I know, but that's a very common convention in any...

Re: 13-limit JI

Let me add that I do know that the recommended notation for 13 is the apotome complement of :/|): :b: , i.e. :(!/: from 27 but I find that even more confusing. The logic of the :(!/: accidental is not obvious for me. Why is it the horizontal mirror of 36:35? I don't see another example of an acciden...

13-limit JI

Hi, I'm trying to get to grips with notating JI in Mixed Sagittal. Is there no dedicated symbol for the 13-comma (27:26)? As I understand it now has to be notated as 36:35 up from a flat :/|): :b: which is confusing. Sure, that's almost the same pitch but that notation doesn't tell you how to find i...
