User:Ganaram inukshuk/TAMNAMS Extension

This is a system for describing and naming mos scales beyond the set of named TAMNAMS mosses. Both User:Frostburn (User:Frostburn/TAMNAMS Extension) and I have similar systems, with the main difference here being how mosses can be named any number of generations away from a named mos.

Naming mos descendants

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 and, optionally, what step ratio is needed for the parent to produce that mos.

Base names
Parent mos		Child (1st descendant)			Grandchild (2nd descendant)			Great-grandchild (3rd descendant)			kth descendant
(mos-name)		(step-ratio)-chromatic (mos-name) (step-ratio)-(mos-prefix)enharmonic			(step-ratio)-enharmonic (mos-name) (step-ratio)-(mos-prefix)enharmonic			(step-ratio)-subchromatic (mos-name) (step-ratio)-(mos-prefix)subchromatic			(kth) (mos-name) descendant (kth)-(mos-prefix)descendant
Step ratio prefixes (optional)
Parent mos		Child (1st descendant)			Grandchild (2nd descendant)			Great-grandchild (3rd descendant)			kth descendant

Mos descendant names have two main forms: a multi-part name, where the base name (chromatic, enharmonic, subchromatic, and descendant) and mos name are separate words, and a one-part name, formed by prefixing the mos's prefix to the base names. The latter is recommended for mosses with no more than three periods, as the only 4 and 5-period mosses named by TAMNAMS are tetrawood and pentawood respectively. If a step ratio is specified for the former, it may be written out fully instead of prefixed to the base word.

The term kth descendant can be used to refer to any mos that descends from another mos, regardless of how many generations apart the two are. To find the number of generations n separating the two mosses, use the following algorithm:

1. 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.
2. Let m1 be equal to max(z, w) and m2 be equal to min(z, w).
3. Assign to z the value m2 and w the value m1-m2. Increment n by 1.
4. If the sum of z and w is no more than 10, then the parent mos is zL ws and is n generations from the mos descendant xL ys. If not, repeat the process starting at step 2.

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 (child), 2nd (grandchild), and 3rd (great-grandchild) 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.

Mosses whose children have more than 10 notes (1st and 2nd descendants only)

Other mos names

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

Names for mos descendants with more than 5 periods

To name mos descendants with more than 5 periods, the names for wood mosses are extended to hexawood, heptawood (or septawood), octawood, nonawood (or enneawood), and decawood. (This is not too different from Frostburn's proposal.) Beyond that, the naming scheme becomes 11-wood, 12-wood, and so on, and mosses are referred to chromatic (number)-wood, enharmonic (number)-wood, and subchromatic (number)-wood. The term (number)-wood descendants is also used, and to refer to nth (number)-wood descendants, the algorithm is used below to find the number of generations:

1. 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.
2. Let m1 be equal to max(z, w) and m2 be equal to min(z, w).
3. Assign to z the value m2 and w the value m1-m2. Increment n by 1.
4. If both z and w are equal to 1, then the parent mos is nL ns and is n generations from the mos descendant xL ys. If not, repeat the process starting at step 2.

Names for wood scales up to 10 periods

Mos	Name	Prefix	Abbrev.
6L 6s	hexawood	hexwud-	hw
7L 7s	septawood or heptawood	sepwud- or hepwud-	sw or hw
8L 8s	octawood	octwud-	ow
9L 9s	nonawood or enneawood	nonawud- or ennwud-	nw or enw
10L 10s	decawood	dekwud-	dkw
11L 11s	11-wood	11-wud-	11wd
12L 12s	12-wood	12-wud	12wd
etc...

Names for mos linear families

Mosses with the same number of large steps can be described as its own family, specifically a family of related mosses of the form xL (nx + y)s. This family starts with the mos xL ys, where x < y and n = 0, and continue with mosses with the same number of large steps but a linearly growing quantity of small steps. An example of such a family is the mos sequence 5L 2s, 5L 7s, 5L 12s, 5L 17s, etc, where each successive mos has 5 more small steps than the last.

Mosses in a linear family are based on repeated applications of the replacement ruleset L->Ls and s->s on the initial mos, and reaching the nth member of a linear family requires the initial mos have a hard or pseudocollapsed step ratio. The child mos (x+y)L xs is the start of its own linear family, which relates back to the initial mos xL ys if the initial mos has a step ratio that is soft or pseudoequalized.

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.

Names for mosses beyond 10 notes (proposed)

This section outlines proposed names and naming suggestions for mosses beyond 10 notes.

Former names worth restoring

At one point, TAMNAMS had tenuously named mosses up to 12 notes. Following reorganization back in August of 2022, many temperament-suggestive names were replaced, and names for 11 and 12-note mosses were dropped. Of those, these names are (in my opinion) worth restoring, either because these names are noteworthy (eg, m- and p-chromatic) or because these temperament-suggestive names are better suited as names for child mosses (eg, 3L 5s was named sensoid).

11-note mosses
Mos	Name	Reasoning
2L 9s	jonatonic	Modification of an old name (joanatonic) that applied to its parent scale
4L 7s	kleistonic	Restoration of an old name
5L 6s	xeimtonic	Restoration of an old name
7L 4s	prasmitonic	Modification of an old name (suprasmitonic)
8L 3s	sentonic	Modification of an old name (sensoid) that applied to its parent scale
9L 2s	villatonic	Indirectly references avila casablanca temperaments
10L 1s	miratonic	Modification of an old name (miraculoid)
12-note mosses
Mos	Name	Reasoning
5L 7s	pychromatic	Modification of an old name (p-chromatic)
6L 6s	hexawood	Extension of -wood scales, already part of other TAMNAMS extension proposals
7L 5s	emchromatic	Modification of an old name (m-chromatic)
11L 1s	ripploid	Restoration of an old name
13-note mosses
Mos	Name	Reasoning
9L 4s	orwelloid	Restoration of an old name that applied to its parent scale

Names for monolarge mosses

These name suggestions are based on a proposal to rename some of the monolarge mosses to be based on gemstones and minerals, following the logic set forth for the name "onyx" for 1L 6s.

Mos	Proposed name	Current name	Reasoning
1L 6s		onyx	"from a lot of naming puns"
1L 7s	spinel	antipine	Contains the substring "pine"
1L 8s	agate	antisubneutralic	Rhymes with eight
1L 9s	olivine	antisinatonic	Rhymes with nine
1L 10s	tanzanite, tenorite		"ten"
1L 11s	helenite		"ele" substring is part of "eleven"
1L 12s	zircon		Zircon is used as a birthstone for December

Other suggestions

Mos(ses)	Notes	Name	Reasoning	Other names
7L 6s	13	tetarquintal	"Quarter fifth" scale, referencing temperaments that divide the fifth into four
11L 2s	13	maioquartal	"Major fourth" scale, as used by Tcherepnin	hendecoid (proposed by Eliora)
12L 1s	13	quasidozenal	"almost twelve"	grumpy tridecatonic (Dwarf Naming Scheme)

Reasoning for names

The overall motivation for these names is to give names to closely related mosses and refer to individual mosses as some member of a broader family, rather than name individual mosses.

The names for the first three generations of mosses are based on existing terms. These terms are open to further changes to make pronunciation easier.

• The phrase chromatic mos is based on former names for the child mosses of diatonic (5L 2s) - p-chromatic for 5L 7s and m-chromatic for 7L 5s - and has seen use on the wiki to refer the children of non-diatonic mosses.
• The phrase enharmonic mos is based off of Discord discussions on how to name grandchild mosses. This has also seen use on the wiki to refer to the grandchild mosses of 5L 2s.
• The phrase subchromatic mos is based on a term coined by Mike Battaglia to describe a scale that is more chromatic than either chromatic or enharmonic. These terms also line up with this page, which describes the progression of a diatonic scale's (or mos's) progression of child mosses.

The format of adding a mos's prefix to the terms descendant, chromatic, enharmonic, and subchromatic is best applied to mosses that have no more than three periods. With mosses that descend directly from nL ns mosses especially (4L 4s and above), this is to keep names from being too complicated (eg, chromatic (number)-wood instead of (number)-woodchromatic).

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 shows the letters diverging from one another, notably where m- is no longer next to p- and f- and s- are no longer along the extremes. Rather than using these letters, as well as being temperament-agnostic, prefixes based on step ratios are used instead. However, temperament-based prefixes may be used specifically for diatonic descendants as alternatives to the prefixes based on step ratios.
