### Re: Multi-Sagittal JI notation (one symbol per prime)

Many thanks to Dave Ryan for pointing out that, in the Multi-Sagittal JI notation, the pythagorean part of the notation for any prime number (its nominal plus sharps or flats) can be determined simply by reducing the prime to the first octave, calculating its size in cents and looking it up in the f...

Sold! Now what? Sleep on it for a few months in case anyone comes up with any objections, before we update sagittal.pdf?

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

George, I note that you have implicitly accepted, without discussion, my proposed cutoffs at fifth sizes narrower than 19-edo and wider than 22-edo. Some might consider that 26-edo should be notated as a meantone. And you have implicitly accepted my suggestion that all such edos with narrow fifths s...

### 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 ...
