Diamond-mos notation: Difference between revisions

Line 61:

The order of the accidentals of the key signature from left to right should follow the generator chain, just like how 12edo key signatures follow the circle of fifths.

=== Modmosses ===

The mos mode written on the score, and represented by the boxes, cannot be a [[MODMOS Scales|modmos]]. However, there is a way to make modmos key signatures to avoid cluttering the score with accidentals. First, we write the key signature corresponding to the tonic as if the mos is not modified. This is so that you can still find the tonic just by counting the accidentals. Next, we add the modmos alterations as extra accidentals to the right of the existing ones. There is a dotted line between the pure mos accidentals and the modmos accidentals to improve clarity. (If the pure key signature is blank, the dotted line is just to the left of the modmos accidentals.) As discussed before, all accidentals in diamond-mos completely override any preceding accidentals. This includes modmos accidentals in the key signature.

== Edo superset notation ==

It’s often a good idea to notate small edos as subsets of larger edos. For example, notating 13edo as a subset of 26edo allows you to use ABC notation. To do this for a diamond-mos score, write “13edo, superset 26edo” at the top of the score. For the purposes of notation, the superset edo is the edo the score is in. However, you can’t stray outside the subset edo, because that wouldn’t make sense.
