I'd like to get a conversation started around something like a key that we could have a standardized format for at the top of scores notated in Sagittal.
I brought it up a couple of times on a private thread between @Dave Keenan and I (viewtopic.php?p=910#p910, if it ever goes public), but these were really early days in our correspondence and I was bombarding him with mountains of big picture questions. Here's the relevant snippet:
The deepest nested quote is from the original Xenharmonikon article. The other two quotes are both from me.I think it could be quite helpful to define a standard format for describing the Sagittal notation used for a piece. At least I think it'd be a good recommendation to state whether you're using an EDO, a JI, or a prime factor notation. For a JI notation it could be nice to give a key for the diacritics you're dropping. For an EDO it might be nice to list the various EDOs the notation supports. Etc.Please let me know if such a standard format has been described yet.Since the Sagittal notation symbolizes intervals that are allowed to vary in size to accommodate many different tunings, it is necessary that sufficient information be provided in a score to specify the particular tuning that is intended, along with a pitch reference. It is expected that this information could be displayed in a standard format that will eventually be defined as a part of the formal specifications of this notation.
Other things I now think might be really handy to mention in such a key:
- size of the fifth (CG) (perhaps if using a non-native fifth for an EDO, you'd want to provide both sizes somehow)
- size of the apotome ( or )
- size of the limma (BC, or do we prefer EF as in the Periodic Table?)
- size of the whole tone (CD)
