Sagittal notation is a universal set of microtonal accidentals, developed by Dave Keenan and George Secor with the help of numerous others. See for the official site.

In order for musicians to evaluate the proposal, they must adopt it enthusiastically to get a feel for what it can do. What Sagittal can notate is directly related to what we want to notate. This page, Sagittal Corner, is meant as a repository for materials which support the exploration of Sagittal notation.
