*A child mos is a ''chromatic mos''. For the child of a named mos, the name is ''chromatic (mos name).''

*A grandchild mos is an ''enharmonic mos''. For the grandchild of a named mos, the name is ''enharmonic (mos name)''.

*A great-grandchild mos is a ''subchromatic mos''. For the great-grandchild of a named mos, the name is ''subchromatic (mos name)''.

*A mos that is more than 3 generations away is called a ''descendant mos''. For the descendant of a named mos, the name is ''(mos name) descendant''. This term can also be used to describe any mos descendant any number of generations away from a named mos.

These phrases may also be shortened by adding the mos's prefix to the terms chromatic, enharmonic, subchromatic, or descendant respectively, if the named mos has no more than 3 periods.

==Names for mos descendants by step ratio==

The designations of chromatic, enharmonic, and subchromatic by themselves does not describe a specific mos descendant. To do that, the name of a step ratio range can be prefixed to the terms ''chromatic'', ''enharmonic'', and ''subchromatic'' (or ''(mos-prefix)chromatic'', ''(mos-prefix)enharmonic'', and ''(mos-prefix)subchromatic''). Specifying the step ratio is optional, and the names for step ratios can be abbreviated into a one or two-letter prefix. (Frostburn's abbreviations can be used here, too.) These prefixes are used for specific descendants, with the notable exception of ''soft'' and ''hard''. For enharmonic mosses, these describe mosses with a step ratio outside the hyposoft and hypohard range. For subchromatic mosses, these describe mosses within the entire soft and hard ranges, producing terminology more specific than just ''subchromatic'' but not as specific as the specific step ratio ranges. These prefixes must include a hyphen.

This section describes additional names for mosses that have more than 10 notes but are worthy of names.

Names for these families describe a subset of a mos descendant family, and most mos families go by the name of ''(mos name)'' ''linear family'' or ''(mos-prefix)linear family''. Mosses in a linear family relate to one another by repeated application of the replacement ruleset L->Ls and s->s to the initial mos's step pattern. In terms of step ratio, these mosses relate back to the initial mos if the initial mos has a hard or pseudocollapsed step ratio. The linear family for the child mos (x+y)L xs can be seen as the analogous linear family for the mos's step ratio being soft or pseudoequalized; however, the mos (x+y)L xs is the start of its own linear family.

Various people have suggested the use of p- and m- as prefixes to refer to specific chromatic mosses, as well as the use of f- and s- for enharmonic mosses. Generalizing the pattern to 3rd mos descendants reveals an issue where the letters started to diverge from one another, notably where m- is no longer next to p- and f- and s- are no longer along the extremes. Rather than to use these letters and to maintain temperament agnosticism, prefixes based on step ratios are used instead.
