Sagittal notation
From Xenharmonic Reference
Sagittal notation is a notation designed for just intonation and equal temperaments. It is based on the Pythagorean chain of fifths with alterations, as with many just notation systems, with the key difference that sagittal notation provides inflections for various composite intervals as well as the primes, and has a formal way of notating EDOs beyond just the application of its just notation.
