There are three types of accidentals in diamond-mos. There are diatonic accidentals (#, b, …), mos accidentals (&, @, …), and ups and downs (^, v, …).

There are three types of accidentals in diamond-mos. There are diatonic accidentals ('''#''', '''b''', …), mos accidentals ('''&''', '''@''', …), and ups and downs ('''^''', '''v''', …).

Diatonic accidentals are what you’d expect. # raises a note by a diatonic chroma, the difference between the diatonic whole tone and semitone. b lowers a note by the same amount. x and bb are the doublings of those. Half-sharp (t) and half-flat (d) represent changes of half a diatonic chroma, and are only allowed if #/b represent an even number of edosteps.

Diatonic accidentals are what you’d expect. '''#''' raises a note by a diatonic chroma, the difference between the diatonic whole tone and semitone. '''b''' lowers a note by the same amount. '''x''' and '''bb''' are the doublings of those. Half-sharp ('''t''') and half-flat ('''d''') represent changes of half a diatonic chroma, and are only allowed if '''#'''/'''b''' represent an even number of edosteps.

Mos accidentals are similar to diatonic accidentals, but for non-diatonic mosses. Mos accidentals are based on the specific mos used. & (read "am") raises a note by a moschroma, the difference between the large mosstep (L) and the small mosstep (s). @ (read "at") lowers a note by the same amount. e and a represent half of & and @ respectively, and are only allowed if &/@ represent an even number of edosteps.

'''e''' and '''a''' represent half of '''&''' and '''@''' respectively, and are only allowed if '''&'''/'''@''' represent an even number of edosteps.

The third type of accidentals are ups and downs. ^ raises by one edostep and v lowers by one edostep. There are double and triple versions, ^^/vv and ^^^/vvv, which represent movements of two and three edosteps respectively. Ups and downs can be combined with the other two types to create compound accidentals, such as ^# and vv@. Note: The ups and downs in diamond-mos don't necessarily follow the same rules as in Kite's original [[Ups and Downs Notation|ups and downs standard]].

Note: The ups and downs in diamond-mos don't necessarily follow the same rules as in Kite's original [[Ups and Downs Notation|ups and downs standard]].

The meaning of &/@ accidentals is dependent on the specific mos being used. &/@ have no meaning on the diatonic staff, so are not allowed in that case. Ups and downs can always be used. If the edo has 5L 2s, the meaning of #/b accidentals is fixed, not dependent on any context. However, in a non-diatonic mos context, #/b have no theoretical significance and could potentially be confusing. We heavily discourage #/b in a non-diatonic mos context for that reason. However, using them could be useful in very large edos where you need all the accidental options you can get.

The meaning of '''&'''/'''@''' accidentals is dependent on the specific mos being used. '''&'''/'''@''' have no meaning on the diatonic staff, so are not allowed in that case. Ups and downs can always be used. If the edo has 5L 2s, the meaning of '''#'''/'''b''' accidentals is fixed, not dependent on any context.

We heavily discourage '''#'''/'''b''' in a non-diatonic mos context for that reason. However, using them could be useful in very large edos where you need all the accidental options you can get.

When using 5L 2s in an edo where t/d are one edostep, we encourage using t/d instead of ^/v. This is to increase consistency with existing microtonal notation, such as notation for 17edo, 24edo, and 31edo. The same rule does not apply to e/a semi-moschroma accidentals.

A subtle but important feature of the standard is that accidentals are separate from each other and do not stack. '''If a note has an accidental in front, that accidental fully overrides any preceding accidentals.''' For example, if a D with a # is followed by a D with only an ^, the second note is D^, not D^#.
