To name mosses that have more than 10 notes, rather than giving mosses unique names, names are based on how they're related to another (named) mos. The following names are used for specific generations - namely child, grandchild, and great-grandchild mosses: | To name mosses that have more than 10 notes, rather than giving mosses unique names, names are based on how they're related to another (named) mos. The following names are used for specific generations - namely child, grandchild, and great-grandchild mosses: | ||
* A child mos is a ''chromatic mos'', or specifically, ''chromatic (mos name)''. For mosses with up to 3 periods this can be shortened to ''(mos-prefix)chromatic''. | * A child mos is a ''chromatic mos'', or specifically, ''chromatic (mos name)''. For mosses with up to 3 periods, this can be shortened to ''(mos-prefix)chromatic''. This term collectively refers to 2 possible chromatic mosses, or any one of them. | ||
* A grandchild mos is an ''enharmonic mos'', or specifically, ''enharmonic (mos name)''. For mosses with up to 3 periods this can be shortened to ''(mos-prefix)enharmonic''. | * A grandchild mos is an ''enharmonic mos'', or specifically, ''enharmonic (mos name)''. For mosses with up to 3 periods, this can be shortened to ''(mos-prefix)enharmonic''. This term collectively refers to 4 possible enharmonic mosses, or any one of them. | ||

For mosses with up to 3 periods, this can be shortened to ''(mos-prefix)subchromatic''. This term collectively refers to 8 possible subchromatic mosses, or any one of them. (Tentative name; open to better suggestions.) | ||
Any mos more than 3 generations away from a named mos is broadly referred to as a '' | Any mos more than 3 generations away from a named mos is broadly referred to as a ''mos descendant'', or specifically ''(mos name) descendant'' or, for mosses with up to 3 periods, ''(mos-prefix)descendant''. These terms can also be used for describing multiple mos descendants, possibly across multiple generations, or to broadly describe any one mos descendant regardless of generation. Optionally, the number of generations can be specified, producing ''nth (mos name) descendant'' or ''nth (mos-prefix)descendant'', using the algorithm below: | ||
# Let z and w be the number of large and small steps of the parent mos to be found. Assign to z and w the values x and y respectively. Let n = 0, where n is the number of generations away from zL ws. | # Let z and w be the number of large and small steps of the parent mos to be found. Assign to z and w the values x and y respectively. Let n = 0, where n is the number of generations away from zL ws. | ||
# Let m1 be equal to max(z, w) and m2 be equal to min(z, w). | # Let m1 be equal to max(z, w) and m2 be equal to min(z, w). | ||
| Line 971: | Line 971: | ||

As diatonic (5L 2s) doesn't have a prefix, the terms ''chromatic'', ''enharmonic'', and ''subchromatic'' by themselves (and with no other context suggesting a non-diatonic mos) refer to 1st, 2nd, and 3rd diatonic descendants. For consistency, mos descendant names apply to mosses whose child | As diatonic (5L 2s) doesn't have a prefix, the terms ''chromatic'', ''enharmonic'', and ''subchromatic'' by themselves (and with no other context suggesting a non-diatonic mos) refer to 1st, 2nd, and 3rd diatonic descendants. For consistency, mos descendant names apply to mosses whose child mosses exceed 10 notes. Since all mosses ultimately descend from some nL ns mos, every possible descendant up to 5 periods will be related to a named mos. | ||

The designations of chromatic, enharmonic, and subchromatic | 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'', which may be used for subchromatic mosses to produce terminology that is more precise than just ''subchromatic'' but not as specific as their step ratio ranges. These prefixes must include a hyphen. | ||
