'''TAMEX''' (from '''''T'''emperament'''-A'''gnostic '''M'''oment-of-Symmetry Scale '''Ex'''tension Description System''), originally devised by [[User:Frostburn|Frostburn]] and [[User:Ganaram inukshuk|Ganaram inukshuk]] as two separate naming schemes, is an extension to the mos pattern names provided by TAMNAMS. This scheme is a means of describing how descendant scales (namely, chromatic and enharmonic mosses) with more than 10 steps relate back to smaller mosses and, to a lesser extent, what step ratios of the original mos is needed to produce that descendant mos. Additionally, it is a means of generalizing the notion of a [[chromatic scale]] to nondiatonic mosses.

Despite looking like a naming system, what TAMEX provides are ''descriptions'' of descendant mosses that relate to a single, TAMNAMS-named mos. Hence, "names" for mosses are meant to be as general as possible and can refer to more than one mos.

* The great-grandchild scale of a ''subchromatic'' mos.
* In general, a mos that is a ''k''th descendant of a named mos is a ''k''th descendant.
* For great-great-grandchild mosses and beyond, the term ''descendant'' is used. Optionally, the number of generations between a named mos and descendant mos can be provided to produce the term k''th-order descendant.''


Descriptions can take on one of two forms: a description as two words, or a single word bearing the mos's prefix. Which one to be used is up the user and whichever form is best depending on context. In the case of ''k''th descendants, the ordinal value ''k''th can be omitted to refer to any or all descendant mosses, depending on context.

=== Calculating the number of generations for ''k''th-order descendants ===
For a mos ''x''L ''y''s, where ''x''+''y'' is greater than 10:
# 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 ''k'' = 0, where ''k'' is the number of generations away from ''z''L ''w''s.
# Let ''m1'' be equal to max(''z'', ''w'') and ''m2'' be equal to min(''z'', ''w'').
# Assign the value ''m2'' to ''z'' and value ''m1''-''m2'' to ''w''. Increment ''n'' by 1.
# If the sum of ''z'' and ''w'' is no more than 10, then the parent mos is ''z''L ''w''s, where ''x''L ''y''s is a ''k''th-order descendant of ''z''L ''w''s. If not, repeat the process starting at step 2.
=== Step ratio descriptions ===
=== Step ratio descriptions ===
Optionally, the names for a step ratio range, describing the step ratio of the root mos, can be added before these descriptions, either as a single word or prefix. Any step ratio range can be used for 4th-order descendants and beyond, as context allows.
