Here's another way of looking at the small-EDO notation problem. I've added lines of constant fifth-size. A JI-based notation can also be an apotome-fraction notation that's designed for fifths of a specific size (or a small range of sizes), so there's no real distinction between apotome-fraction an...

I just received the following welcome email from Daniel Spreadbury of Steinberg: Hi Dave, George, It’s been a while! I hope the two of you are keeping well. I just wanted to drop you a line to let you know that Dorico Pro 2 came out just over three weeks ago, and has an initial implementation of pla...

Well George, we've slept on it for 9 months now, and there has recently been a request on one of the facebook groups, for someone to add the corresponding Sagittal notation(s) to every EDO entry in the Xenharmonic Wiki. So we really ought to decide whether these will become the new standard notation...

Relative to the notations given in http://sagittal.org/sagittal.pdf at the time of writing, this proposal will add native-fifth notations for the following seventeen EDOs: 6, 8, 11, 13, 18, 20, 25, 28, 30, 32, 35, 37, 42, 52, 54, 59, 71. And it will change the existing native-fifth notations for the...

Here's is the final version, which George and I agree on, of all the EDO native-fifth notations resulting from this proposal. First we show all of the proposed apotome-fraction notations. These are for the EDOs whose best fifths are more than 7.5 c wider than just (> 709.5 c) (wider than those of 22...

Margo, I believe your notation is the best possible Sagittal notation for those tunings. I note that since (|) is the apotome-complement of /|\, you can avail yourself of alternative spellings such as Bb/|\ (B flat vai) = B(!) (B wao). Also, you may find it more convenient to use the shorthand way o...

Thanks for those, Margo. My apologies for the delay in the appearance of your posts. The first post by every new member must be approved by a moderator (me) as an anti-spam measure. But at least in this forum, once that first post is approved you have full access and full capabilities, unlike the Xe...

The only difference between the notation above, and that given earlier in this thread (for 5 nominals), is that :~~|: has been eliminated, and the use of :)~|: has been extended to include 1/4 and 1/5 apotome. So only the 20-edo and 25-edo notations have changed. 5edo: C D E G A 10edo: C D:\!): D E:...

We now have a better rationale for 5n-edo notations (and other "bad fifth" EDOs), thanks to suggestions by Cryptic Ruse / Igliashon Jones. See this thread: http://forum.sagittal.org/viewtopic.php?f=5&t=256 The proposal looks like this for 5n-edos (in mixed Sagittal): 5n-edos: A:B C:D D...

George wrote in email (on 2016-Sep-30): Oops, you're right! |||~) would have been 7:23S (45927:47104) + an apotome, which we might have been considering at one time, but we chose 5:13M (405:416) instead. For some reason I never updated my EDO-degrees spreadsheet with the change. Fortunately, a symbo...
