'''TAMNAMS''' (read "tame names"; from '''''T'''emperament-'''A'''gnostic '''M'''os '''NAM'''ing '''S'''ystem''), devised by the XA Discord, is a system of temperament-agnostic names for small octave-[[mos]] scales, their intervals and their associated generator ranges, taking into account the relative sizes of large and small steps. | '''TAMNAMS''' (read "tame names"; from '''''T'''emperament-'''A'''gnostic '''M'''os '''NAM'''ing '''S'''ystem''), devised by the XA Discord, is a system of temperament-agnostic names for small octave-[[mos]] scales, their intervals and their associated generator ranges, taking into account the relative sizes of large and small steps. | ||

The TAMNAMS system names nine specific simple [[Blackwood's R|L:s ratios]]. These correspond to the simplest edos that have the mos scale. | The TAMNAMS system names nine specific simple [[Blackwood's R|L:s ratios]]. These correspond to the simplest edos that have the mos scale. | ||

To denote interval classes within the mos, TAMNAMS uses the generic prefix ''mos-'', or the specific prefixes and abbreviations listed under ''mos pattern names''.

* The pattern continues, ddd for triply diminished and AAA for triply augmented. Note that applying this operation more than 3 times is an unlikely usecase, and a shorthand notaton of d^3 and A^3 or an alternative notation or terminology entirely would likely be preferable in such circumstances, hence repetition of the corresponding letter is a sufficient system. | * The pattern continues, ddd for triply diminished and AAA for triply augmented.

The following names are suggested for selected small mosses. These names are optional; interval size names and step ratio names can be combined with conventional ''xL ys'' names. For example: ''21edo is the soft [[5L 3s]] tuning and its major mosthird is a neutral third of size 342.9 cents.'' (Pattern names are the least important part of TAMNAMS.) | The following names are suggested for selected small mosses.
