| This interval…
* Approximates the [[48/25|Classic Diminished Octave]] or Diptolemaic Diminished Octave, and thus…
:* It frequently acts as a Diminished Octave in Western-Classical-based harmony
* Approximates the [[25/13|Lesser Tridecimal Diminished Octave]] and the [[52/27|Greater Tridecimal Diminished Octave]]
* Is the closest approximation of 17edo's Major Seventh found in this system, and thus…
:* Is capable of being used for similar modulatory moves, albeit with caveats, since such moves on their own don't work the exact same way in this system

| This interval…
* Approximates the [[27/14|Septimal Supermajor Seventh]], and thus…
:* Is the narrowest interval that has the potential to move directly up to the Tonic as a Lead in Western-Classical-based harmony and Neo-Medieval harmony
::* Compared to other options, it has a markedly more tense feel
:* Can be used as an unexpected option for a Diminished Octave in Western-Classical-based harmony
* Is the closest approximation of 19edo's Diminished Octave found in this system, and thus…
:* Is capable of being used for similar modulatory moves, albeit with caveats, since such moves on their own don't work the exact same way in this system
* Can be used for tonality-flux-based chord progressions

|  
| This interval…
* Approximates the [[64/33|Alpharabian Infraoctave]], and as such…
:* It functions as the inverse of the default parachromatic quartertone in Western-Classical-based Paradiatonic functional harmony, 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 up to the Tonic through a Parachromatic quartertone motion
::* Has the potential to move away from the Tonic back towards either a Lead or Subtonic harmony through a type of Diatonic or Paradiatonic semitone motion
* Is the closest approximation of 22edo's Greater Major Seventh in this system, and thus…
:* Can be used in Superpyth-based melodic and harmonic gestures reminiscent of those found in that system, albeit with caveats, since such moves on their own don't work the exact same way in this system
* Is the closest approximation of 24edo's own Infraoctave 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
* Is one of the more important intervals for use in tonality-flux-based chord progressions

::* It cannot occur as the distance between any two notes in a single chord in Western-Classical-based polypedal harmony due to its dissonance
:* It functions like an Ultramajor Seventh in that…
::* It can be used in Western-Classical-based harmony as part of a contrapuntal passage in which both of the notes separated by this interval in one voice work well against the notes in all other voices
::* It can be used in Western-Classical-based harmony for hidden voice-leading in the middle voices
* Is one of the more important intervals for use in tonality-flux-based chord progressions

* Approximates the [[88/45|Undecimal Suboctave]]
* Approximates a complex 11-limit Paradiatonic quartertone that is the namesake of 24edo's own Ultramajor Seventh
* Is the closest approximation of 31edo's own Suboctave found in this system, and thus…
:* Is capable of being used in progressions reminiscent of that system's spiral progressions
* Is a dissonance to be avoided in Western-Classical-based harmony unless…
:* Used for tonality-flux-based chord progressions
:* Used in a contrapuntal passage in which both of the notes separated by this interval in one voice work well against the notes in all other voices
:* Deliberately used for expressive purposes
* Is useful in melody as…
:* A non-chord passing tone
:* The destination for a glissando
