I think I cracked it: They are intended to be a short way to specify (other?) capture zones for the symbols: the apotome fraction lower bound for upward pointing symbol is the "EDA value" minus a half, divided by the EDA steps (i.e. \(\frac{v-\frac12}s\)), and for downward pointing symbols the same ...

I thought the reason for the post was that you wanted me to explain more fully what I mean when I assign modular generator counts to periods and how I think about the subject. Yes, please. Feel free to ignore my suggestions. I want to understand how you see it. Maybe I need to see some lattice ...

Good questions. George chose those numbers. But I'm pretty sure the part after the decimal point was intended as an approximate decimal-fraction part of a number of steps, not merely a distinguishing or ordering mark. You can see in George's original version of the JI Calculator spreadsheet , that ...

I think it's probably better to start a new one, or maybe even two (although they could be separate posts on the same thread): One about general notation guidelines I found helpful for notating linear temperaments, and one about the problems and my approach to them when dealing with temperaments ...

I thought I understood, but perhaps I don't. If you can work out a general theory of chain-of-fifths-plus-microtonal-accidentals notations for rank 2 temperaments, that would be wonderful. Particularly if it could be derived from a mapping for the temperament. It should preferably use the standard ...

I get it now. I think you are confusingly overloading the words "generator" and "complexity". I think we can do better than either of the two ways you addressed it, but I don't want to spend the time to set out examples in detail. So I'll just give the most important points. 1. I think there is no ...

... formal fractions ... I think "formal fractions" is an excellent name. Obvious now that you've given it. Captures the idea perfectly. And from a non-native English speaker. Well done. I don't understand or find any use for Douglas's ideas of locking just the numerator, or just the denominator ...

Yes, the number of accidentals needed in a chain of fifths notation for a rank-2 temperament is exactly the complexity of the fifth in that temperament ... How are you defining, or calculating, the complexity of a given interval in a given temperament? Thanks for the Evo notation. I agree it offers ...

That staff showing an 18 note scale where every note has a different accidental is like a parody of a chain-of-fifths notation. It's the kind of thing that is likely to scare anyone away from ever considering Sagittal notation. But it's not Sagittal's fault. And it's not your fault. I spent several ...

This is all good thinking. I prefer :~|::|: to :)|\\: in the 255edo notation. You have convinced me that we should create symbols with the following codepoints and names: Spartan Sagittal multi-shaft accidentals [using unused values near the end of the existing section ]: U+E336 ...
