* Approximates the [[33/32|Al-Farabi Quartertone]] | * Approximates the [[33/32|Al-Farabi Quartertone]], and thus... | ||
:* Functions as the default parachromatic quartertone in Western-Classical-based harmonic functionally, and thus... | |||
::* Can be used more overtly in both melodic and harmonic voice-leading in general, though doing so in Western-Classical-based music requires a proper set-up | |||
::* Cannot occur as the distance between any two notes in a single chord in Western-Classical-based polypedal harmony due to its dissonance | |||
::* Has the potential to move directly back down to the Tonic through a parachromatic motion | |||
::* Has the potential to move away from the Tonic towards either a Contralead or Supertonic harmony through a diatonic or paradiatonic motion | |||

* | :* Is capable of being used in certain similar melodic and harmonic gestures, albeit with caveats, since the biyatisma is not tempered out | ||
* Is the closest approximation of 24edo's own Ultraprime in this system, and thus... | |||
:* Follows similar interval arithmetic logic in relation to Pythagorean intervals, albeit with caveats, since the rastma is not tempered out | |||
