I am trying to make a 37edo template on Mus2 for Joe Monzo, but I didn't find any obvious solution to notating 37, except as a subset of 74edo's meantone (which I don't think he's interested in).
If notating with the native fifth, we have m2 = 1\37, A1 = 6\37, M2 = 7\37, etc.
The most obvious option next seemed to me to be to notate 2\37 as either
, and it seems they're both equal here (so
is tempered out?). I chose to use
to keep primes small, and make major and minor thirds/sixths etc pretty intuitive.
is tempered out, and
, the next highest prime to look at was 13, and I found that
corresponds to 3\37, along with
. I picked
, but I guess it doesn't matter. Maybe the convention is to take the smaller alteration.
However, I was wondering what to do with notations for 1\37. Taking the difference between my accidentals for 2\ and 3\ I ended up with 65:64, but that's notated as
, which I thought would be far too confusing as the septimal comma is tempered out. Using the other 13-diesis gave me 40:39, which is usually notated as ://|:
Another option was to use
to notate prime 19, but then the symbol's size is inflated almost by a factor of 10.
What would you do?
