Diamond-mos notation is designed specifically to visually represent mos logic for compositions using mosses and to be generalizable across different mos patterns. It does not attempt to be a universal system that represents every microtonal theoretical school. It attempts to be back-compatible with standard notation and keep new symbols and memorization required to a minimum. In addition, diamond-mos includes visual aids and redundancies to make reading music in unfamiliar systems easier. | Diamond-mos notation is designed specifically to visually represent mos logic for compositions using mosses and to be generalizable across different mos patterns.

Diamond-mos notation is based in a specific edo 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 edo at a given time, written at the top of the score.

There’s an exception to the rule that diamond-mos notation is always based on an edo. There is also the option of specifying a mos tuning which does not come from an edo. At the top of the score, write “Non-edo mos tuning” and specify the exact size of the generator. Instead of writing the mos mode in edosteps, use generic mos pattern notation, e.g. “LLsLsLs”. When using non-edo notation, ^/v have no meaning and are disallowed. The only available accidentals are the mos-based &/@/e/a accidentals (or #/b/t/d if using 5L 2s). Since non-edo notation doesn’t use a fixed, finite set of pitches, retuning to an arbitrary scale is disallowed. | There’s an exception to the rule that diamond-mos notation is always based on an edo.

It is acceptable to treat equal scales (sub-edos of the edo used for notation) as mosses for notation in diamond-mos, for example 9edo in 18edo. In that case, &/@ have no meaning and are disallowed. There are also no boxes on the staff. | It is acceptable to treat equal scales (sub-edos of the edo used for notation) as mosses for notation in diamond-mos, for example 9edo in 18edo.

It is acceptable to use 5L 2s-based notation even for edos where the best fifth is 4\7 or 3\5. This is for consistency with existing microtonal notation that allows this. In the case of 4\7, #/b technically alter notes by zero edosteps, so they’re disallowed. [[TAMNAMS#Step ratio spectrum|Equalized]] and [[TAMNAMS#Step ratio spectrum|paucitonic]] tunings are only allowed for 5L 2s, not other mosses. | It is acceptable to use 5L 2s-based notation even for edos where the best fifth is 4\7 or 3\5.
