The darker modes could be used to distort diatonic tropes that start from the tonic and work downwards (because the melodically squashed fifth from the tonic downwards is the flatter 5th degree, the minor tritone), while the brighter modes such as Dylathian and Celephaisian play on upwards-moving diatonic tropes, with the sharper 5th degree functioning as a melodic fifth when moving from the tonic up.

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. | When working up from the tonic, the darker modes are radically different in character than the brighter modes.
