Diamond-mos notation is based in a specific edo or other tuning at a given time, written at the top of the score. Within that edo, the naturals on the staff represent a specific mos. The mos pattern is written in edosteps at the top of the score, e.g. “33133131”. The natural staff notes are the specific mode written, starting from middle C.
Diamond-mos notation is based in a specific tuning (such as an edo) at a given time, written at the top of the score. Within an edo, the naturals on the staff represent a specific mos.

Diamond-mos notation treats the diatonic mos ([[5L 2s]]) as special. If you’re using 5L 2s, diamond-mos looks like standard music notation. It uses standard clefs, #/b accidentals, and ABCDEFG note names. If you're using 5L 2s, you don't need to write the mos pattern on the score, only the edo. If the edo you’re using has 5L 2s, its notes can be used as an unchanging reference other mosses can be compared against. For example, you might say “P@ = Bb” to provide a reference for which note P@ is.

When using a non-diatonic mos, the mode you write for notation should be the mode you’re writing in. This soft rule allows you to figure out the tonic just by looking at the key signature, as explained later. We call this a soft rule because there are situations where it makes less sense, such as if the tonic is ambiguous or shifting. If you break this rule, we would suggest making a note on the score when you do.

The score should include the text "This score uses the diamond-mos notation standard. Visit xen.wiki for more information." This ensures that someone reading the score can easily find information about how to read it.

It is possible to change the edo and/or the mos pattern mid-score. Just write the same information you would write at the top of the score at the bar where the change happens.
