In 5edo:
 
* [[ups and downs notation]] is identical to standard notation, since no [[arrow]]s are required;
[[:File:5ed2-001.svg|5ed2-001.svg]]
* mixed [[sagittal notation]] is identical to standard notation, but pure sagittal notation exchanges sharps (#) and flats (b) for sagittal sharp ([[File:Sagittal sharp.png]]) and sagittal flat ([[File:Sagittal flat.png]]).
 
== Notation ==


=== Alternative notations ===
* via Reinhard's cents notation
* via Reinhard's cents notation
* a four-line hybrid treble/bass staff.


* naturals on a five-line staff, with enharmonics (used interchangably) E=F and B=C
* a four-line hybrid treble/bass staff.
Intervals can be named penta-2nd, penta-3rd, penta-4th, penta-5th and octave.
Intervals can be named penta-2nd, penta-3rd, penta-4th, penta-5th and octave.


Line 85: Line 124:


For note names, Kite omits B and merges E and F into a new letter, "eef" (rhymes with leaf). Eef, like E, is a 5th above A. Eef, like F, is a 4th above C. The circle of 5ths is C G D A Eef C. Eef is written like an E, but with the bottom horizontal line going not right but left from the vertical line. Eef can be typed as ꘙ (unicode A619) or ⊧ (unicode 22A7). Eef can also be used to notate [[15edo]].
