When using a mos different from 5L 2s, diamond-mos notation does not have traditional clefs. Instead, octaves on the staff are marked with diamonds on the left edge of the staff. The notes marked with diamonds are named J. The large diamond marks “middle J”, which is enharmonic to middle C. The point of the diamonds is to provide a visual reference for where the octaves are. It would be difficult to sightread otherwise, especially when using non-heptatonic mosses.

The mos pattern is marked on the score too. Just to the right of the diamonds, little boxes mark the steps of the mos. Hollow boxes represent small mossteps (s) and filled boxes represent large mossteps (L). To avoid clutter, only the small mossteps or the large mossteps are marked. The ones which get marked are the ones the mos has fewer of. (In the case of nL ns mosses, either is fine.) The boxes are another tool to make reading the score easier.

The staff can be extended up and down to have more than 5 lines when using non-~~heptatonic mos notation~~. You should use at least as many staff lines as is required to fit an octave in the staff. When ~~extra~~ staff lines are used, at least one of the staff lines should be bolded. ~~This~~ doesn't ~~add information~~ but ~~helps with~~ readability.

The staff can be extended up and down to have more than five lines when using non-diatonic mosses. You should use at least as many staff lines as is required to fit an octave in the staff, which for an n-tone mos is ceil(n/2 + 1). When more than five staff lines are used, at least one of the staff lines should be bolded. The bolded line doesn't represent anything in particular, but provides an extra visual reference for readability.
