Analogously to 2-step scales including mosses, scales with three step sizes L > M > S, including [[MV3]] scales, can also be defined by their L:M:S ratios. Here TAMNAMS names the L/M ratio and then the M/S ratio as if these were mos step ratios: for example, [[21edo]] [[diasem]] (5L 2M 2s, LMLSLMLSL or its inverse) has a step ratio of L:M:S = 3:2:1, so we name it "soft-basic diasem". | Analogously to 2-step scales including mosses, scales with three step sizes L > M > S, including [[MV3]] scales, can also be defined by their L:M:S ratios.

=== Naming MV3 intervals === | |||
[[MV3]] scales have at most 3 sizes for each interval class. For every interval class that occurs in exactly 3 sizes, we use "large", "medium" and "small k-step". For every interval class that occurs in 2 sizes, we use "large k-step" and "small k-step". If an interval class only has one size, then we call it "perfect k-step". | |||
