Re: Notation for Oneirotonic 8 nominal scale

So a chain of 7/18-octave generators would be notated Q:!!!): L:!!!): O:!!!): J:!!!): M:!!!): P:!!!): K:!!!): N:!!!): Q L O J M P K N Q:(|||: L:(|||: O:(|||: J:(|||: M:(|||: P:(|||: K:(|||: N:(|||: . Of course, that's 24 notes. You only need the middle 18 to notate 18edo. In pitch order, 18edo could...

Re: Notation for Oneirotonic 8 nominal scale

Sagittal is primarily a universal set of accidentals. We've always said they can be used with notations having other than 7 nominals, but we've never got into how best to do that on a staff. So we can't help you with the latter, but we can suggest a suitable accidental to use in extending the chain ...

Re: The origin of Sagittal

Here's a significant thread from the early days of Sagittal. It includes the introduction of arcs.

Re: general methods for linear temperament notation

Also, I suspect @Dave Keenan may eventually ask me to write a program which allows a regular (or is linear the preferred term?) temperament notation to be generated from some inputs, as a feature of a web-based Sagittal notation calculator... Actually. It should be a simple extension to your existi...

Re: myna temperament notation

Good work there, Herman! I'm sorry I can't spare the time to investigate enough to suggest any alternatives.

It certainly underscores the point that linear temperament notations are still more art than science.

Re: Quadritikleismic (68&72 13-limit)

I now wonder which accidentals would be best for using in [Quadritikleismic], besides :/|\: and :(!/: ? It should preferrably be a good compromise between 72edo and 68edo, and possibly 140edo. With 4 periods to the octave and 6 generators to the fifth, notation of Quadritikleismic, based on diatoni...

Re: Quadritikleismic (68&72 13-limit)

Hi Henrik. Welcome to the Sagittal forum. I include this link to your related facebook thread in case some readers here haven't seen it. My understanding of your facebook post is that you weren't particularly asking about a notation for it, but just wanted to know if anyone had any information about...

Re: miracle temperament

As for the extra symbols beyond the 72-EDO notation, I like being able to name a pitch by reference to the nearest nominal ... Right. That's fair enough. It's similar to the way that we could notate 31edo using only sharps and flats and their doubles, but that would required that we accept "cr...

Re: miracle temperament

Hey... shouldn't Sagittal offer a miracle temperament notation, since George himself invented it? It does. It's the 72edo notation. In the last paragraph on page 18 of the XH article you will find: While the notation of linear or higher-dimensional temperaments has not been investigated by us in gr...
