== Notation ==

=== ~~Ups and downs~~ notation ===

=== Stein–Zimmermann–Gould notation ===

~~25edo can be notated with~~ [[~~ups and downs~~]]~~, spoken as up, dup, dudsharp, downsharp, sharp, upsharp etc.~~ and ~~down, dud, dupflat etc. Note that dudsharp is equivalent to trup (triple-up) and dupflat is equivalent to trud (triple-down).~~

[[Stein–Zimmermann–Gould notation]] uses sharps and flats with arrows:

~~Another notation uses [[Alternative symbols for ups and downs notation#Sharp-5|alternative ups and downs]]. Here~~, ~~this can~~ be ~~done~~ using ~~sharps and flats with~~ arrows~~, borrowed from extended [[Helmholtz–Ellis notation]]:~~

If the arrows are taken to have their own layer of enharmonic spellings, then in some cases notes may be best denoted using triple arrows.

=== Kite's ups and downs notation ===

25edo can be notated with [[Kite's ups and downs notation|Kite's ups and downs]], spoken as up, dup, dudsharp, downsharp, sharp, upsharp etc. and down, dud, dupflat etc. Note that dudsharp is equivalent to trup (triple-up) and dupflat is equivalent to trud (triple-down).

~~If the arrows are taken to have their own layer of enharmonic spellings, then in some cases notes may be best denoted using triple arrows.~~

=== Sagittal notation ===

This notation uses the same sagittal sequence as [[32edo#Sagittal notation|32edo]], and is a superset of the notation for [[5edo #Sagittal notation|5edo]].

This notation uses the same sagittal sequence as [[32edo #Sagittal notation|32edo]], and is a superset of the notation for [[5edo #Sagittal notation|5edo]].
