'''Trachytonic''' is the 7-note MODMOS LLmmLLs. It is usually tuned in 17edo (that is, 3322331). It is not a maximally even scale (since seconds, thirds, sixths, and sevenths all come in three rather than two sizes). However, it is notable for being [[Rothenberg_propriety|strictly proper]], whereas the 17edo diatonic scale is not proper at all, and the 12edo diatonic scale is proper but not strictly so.

'''Trachytonic''' is the 7-note MODMOS LLmmLLs, which is the pattern of the maqam [[Bayati]] taken as a scale in the context of Western xenharmonic theory.

The scale and its modes have alternative "Simpsonsesque" names by Mason Green, where the scale itself is called "'''screamapillar'''", which comes from an analogy with [[Scorp|scorp]] (as both names are related to arthropod creatures starting with "sc", which in this case is a reference to a character from the Simpsons TV show), and also because the major fourth of 17edo (which functions as 11:8, among others) has a very bright sound as though it is "screaming"'; ambulance sirens often use similar intervals. Timbres where the eleventh harmonic is strong tend to take on a similar character.
