The darker modes could be used to distort diatonic tropes that start from the tonic and work downwards, while the brighter modes such as Dylathian and Celephaisian play on upwards diatonic tropes. For example: | The darker modes could be used to distort diatonic tropes that start from the tonic and work downwards, while the brighter modes such as Dylathian and Celephaisian play on upwards-moving diatonic tropes. For example: | ||
*Sarnathian | *Sarnathian is like downwards melodic minor (When starting from the octave above, the 4th degree sounds like a minor third; it's actually a diminished fourth.) | ||
* | *Hlanithian is like downwards melodic major (the 4th degree sounds like a major third; it's actually a minor fourth.) | ||

When working up from the tonic, the darker modes are radically different in character than the brighter modes. Because | When working up from the tonic, the darker modes are radically different in character than the brighter modes. Because the fifth and seventh scale degrees become the more consonant minor tritone and the minor sixth respectively, the flat tritone sounds more like a stable scale function. Hlanithian, in particular, is a lot like a more stable version of the Locrian mode in diatonic. Close-to-optimal petrtri temperaments such as [[34edo]] may be particularly useful for Sarnathian, as Sarnathian in these tunings uniquely approximates four over-2 harmonics plausibly, namely 17/16, 5/4, 11/8, and 13/8. | ||
=== Important MODMOSes === | |||
The most important oneirotonic MODMOS is LSLLLSLS, because it allows one to evoke upwards diatonic modes where three whole steps in a row are important, like Dorian, Phrygian, Lydian or Mixo in an octatonic context, without using an equi-heptatonic scale like glacial[7]: | |||
