Flavors of Sagittal notation: Evo-SZ is not limited to /|\ and \!/ substitutions
Line 10: Line 10:
The '''Evo''' flavor (short for "evolutionary", previously called "mixed") uses only single-shaft Sagittal symbols, e.g. {{sagittal| /| }} {{sagittal| \! }} {{sagittal| |) }} {{sagittal| !) }}, alone or in combination with conventional sharps and flats and their doubles. Only the large variant of the double sharp {{sagittal| x }} (U+E47D) is considered to be stylistically-compatible with Sagittal symbols. Evo is much easier to learn, but it results in a greater number of symbols on the sheet, which can give it a more cluttered appearance, particularly with chords, and it may be confusing when two symbols alter the same note in opposite directions.

<span id="Evo-SZ"></span> A sub-flavor of Evo is '''Evo-SZ''' (Evo with Stein-Zimmermann). This is where the arrow-like [[33/32|11M]] up and down symbols {{sagittal| /|\ }} {{sagittal| \!/ }} are replaced by the Stein-Zimmermann semisharp {{sagittal| > }} and narrow reversed flat {{sagittal| < }}. This should only be done when the 11M symbols notate exactly half the alteration of a sharp or flat. Similarly, the combinations {{sagittal| /|\ }}{{sagittal| # }} and {{sagittal| \!/ }}{{sagittal| b }} are replaced by {{sagittal| ># }} and {{sagittal| <b }}. The narrow variants of the fractional flats {{sagittal| < }} (U+E284) and {{sagittal| <b }} (U+E285) are preferred because they preserve the Sagittal principle that the visual size of a symbol should indicate the relative size of its alteration.
<span id="Evo-SZ"></span> A sub-flavor of Evo is '''Evo-SZ''' (Evo with Stein-Zimmermann). This is where any sagittals that are notating exactly half the alteration of a sharp or flat (most often {{sagittal| /|\ }} {{sagittal| \!/ }}) are replaced by the Stein-Zimmermann semisharp {{sagittal| > }} and narrow reversed flat {{sagittal| < }}, and the corresponding combinations (most often {{sagittal| /|\ }}{{sagittal| # }} and {{sagittal| \!/ }}{{sagittal| b }}) are replaced by {{sagittal| ># }} and {{sagittal| <b }}. The narrow variants of the fractional flats {{sagittal| < }} (U+E284) and {{sagittal| <b }} (U+E285) are preferred because they preserve the Sagittal principle that the visual size of a symbol should indicate the relative size of its alteration.
