Re: A proposal to simplify the notation of EDOs with bad fifths

For the benefit of other readers, I note that if I used asterisks in the way George has done, in my proposal, I think every symbol would have an asterisk, most would have two. I agree that where a spartan is valid in its primary comma role we should use it there, as you have done with pai :/|: and t...

Re: A proposal to simplify the notation of EDOs with bad fifths

That's great stuff George. Thanks. To help folks evaluate it (OK, to help me ), I have a couple of requests. 1. Could you please give a table showing all the symbols you have used, in size order, and which apotome and limma fractions they correspond to. Similar to the one of mine that you quoted. 2....

Re: Notation for Fibonacci tuning (Wilson's horogram #22)?

Hi Herman. That's a tough one! Not intended to approximate JI. 12 generators before you get a decent fifth.

Can you tell me how many generators each alteration in your list corresponds to? And what mapping you have assumed, if any?

Re: List of 7-prime limit / 6125-odd limit accidentals

Just to make sure that I understand systematic comma names correctly: 25:28 = +-[4 0 -2 1> (not in Olympian set) would be 7:25MS+A, and 1792:2025 = +-[-8 4 2 -1> (contained in Olympian set) would be c7:25MS+A, correct? Those are absolutely correct. Well done. Some of the ratios in the Olympian set ...

Re: List of 7-prime limit / 6125-odd limit accidentals

Ok, I finished the list of 7-limit ratios (including lower limits) with an exact Olympian representation: 7-limit Olympian set.pdf Nicely done. You could include the proper Sagittal symbols in the PDF, at higher resolution than the forum smilies, if you install the Bravura font. Unfortunately, ther...

Re: A proposal to simplify the notation of EDOs with bad fifths

Here are all of the proposed apotome-fraction notations. These are the EDOs whose best fifths are wider than those of 22-edo (> 709.5 c). Those on the same row have the same number of steps per apotome, and differ only in the spacing of their nominals. This spacing can be obtained from the chart at ...

Re: List of 7-prime limit / 6125-odd limit accidentals

Sorry for the late reply! I reread sagittal.pdf and your replies to make sure I understand enough about Sagittal notation with Olympian precision. I think I'm now more or less equal to the task of completing the list of 7-limit accidentals with Olympian precision. Well done. But I have a question: ...
