	'''Diamond-MOS notation''' is a notation for MOS systems, which aims to avoid potential conflicts with diatonic notation by introducing a new set of symbols and attempting to make the MOS itself as easy to read as possible. Diamond-MOS notation replaces letters, clefs, accidentals, key signatures, and pitch correspondences with notes, while keeping all other aspects of diatonic notation the same.		'''Diamond-MOS notation''' is a notation for MOS systems, which aims to avoid potential conflicts with diatonic notation by introducing a new set of symbols and attempting to make the MOS itself as easy to read as possible. Diamond-MOS notation replaces letters, clefs, accidentals, key signatures, and pitch correspondences with notes, while keeping all other aspects of diatonic notation the same.

	== ~~Premise~~ ==		== Note names ==
	The letters starting from J are used to indicate the nominals in a given MOS. The MOS and its chosen mode and tuning are written at the top of a score notated in diamond-MOS. The mode is for the nominals on middle J, which is the same as middle C. So, to notate blackwood major in diamond-MOS, [15edo] [2-1-2-1-2-1-2-1-2-1] might be used (or a different edo that supports the scale, such as 25). The accidentals for a MOSchroma are @ (which lowers a note, i.e. "flat" = "at") and & (which raises a note, pronounced "am"). That way, J-M-P in blackwood major would be a major triad, and J-@M-P would be a minor triad. Any new accidental cancels all previous ones, similarly to [[Ups and downs notation\|ups and downs]] notation.

	== ~~Clefs~~ ==		=== Nominals ===
	~~[[File:Diamond mos 1.png\|thumb\|~~A ~~diamond-mos clef and barline.]]~~		To avoid collision with diatonic notation (which uses letters from A to G, as well as H in some countries) and with the Roman numeral I, the starting letter for diamond-mos is J, which corresponds to C in standard notation and indicates the "middle note" and the start of the scale being referenced. The nominals continue JKLMNOPQRSTUVWXYZ, allowing for MOS scales with up to 17 notes (such as argent[17]) to be notated.
	~~Diamond-mos clefs indicate the location of middle J with the large diamond~~, and ~~additional J notes~~ with the ~~smaller diamonds~~, ~~indicating octaves. To~~ the ~~right of the diamonds~~, ~~small boxes are placed~~ to ~~represent steps of the MOS - hollow boxes represent small mossteps and filled boxes represent large mossteps (think of a piano, where small diatonic steps have no black key~~ in ~~between,~~ and ~~large diatonic steps do). Note that~~ the ~~only steps marked are~~ the ~~kind which~~ the MOS ~~has fewer of~~ (~~so ssLssssLss would be marked with two filled boxes and nothing else~~)~~. These boxes are repeated on every barline~~ to ~~aid sightreading, and on ledger lines~~.

	== ~~Etc~~ ==		=== Accidentals ===
	[[~~File:Imageyh~~.~~png~~\|~~thumb~~]]		To avoid collision with diatonic notation, and to account for cases where the diatonic # and b accidentals may remain useful (such as in [[Ploidacot\|complexity]]-2 or -3 temperaments), the accidentals for a MOSchroma are @ (which lowers a note, i.e. "flat" = "at") and & (which raises a note, pronounced "am"). That way, J-M-P in blackwood major would be a major triad, and J-@M-P would be a minor triad. Any new accidental cancels all previous ones, similarly to [[Ups and downs notation\|ups and downs]] notation.
	Diamond-mos notation may be combined with [[ups and downs notation]] in an edo.
			Diamond-mos notation may be combined with [[ups and downs notation]] in an edo, and when the moschroma is only 1 edostep, the up or down is often preferred. Otherwise, ups and downs may represent a specified [[subchroma]].

			== The score ==

			=== The heading ===
			The MOS and its chosen mode and tuning are written at the top of a score notated in diamond-MOS. The mode is for the nominals on middle J, which is the same as middle C. So, to notate blackwood major in diamond-MOS, [15edo] [2-1-2-1-2-1-2-1-2-1] might be used (or a different edo that supports the scale, such as 25).

			=== Clefs ===
			Diamond-mos clefs indicate the location of middle J with the large diamond, and additional J notes with the smaller diamonds, indicating octaves. To the right of the diamonds, small boxes are placed to represent steps of the MOS - hollow boxes represent small mossteps and filled boxes represent large mossteps (think of a piano, where small diatonic steps have no black key in between, and large diatonic steps do). Note that the only steps marked are the kind which the MOS has fewer of (so ssLssssLss would be marked with two filled boxes and nothing else).

			=== Key signatures ===
	Key signatures follow similar rules to diatonic key signatures, indicating the number and location of alterations from the listed scale to a different one. For instance, to modify ssLssssLss on J to sssLssssLs, @ symbols are placed on the positions representing the third and eighth degrees of the scale.
