These intervals are invariably inside the Tonic's uncanny valleys, and the uncanny valleys around the Tonic, unlike those around the other two functions, are very deep, and as a result, wolf intervals around the Tonic are only tolerable in melody and ornamentation but not harmony. Thus, these intervals cannot be directly approached, even melodically, and so they're usually avoided outside of modulation. | ||
'''Supercommatic''' - This is a note that occurs at intervals from about 3.5 cents to roughly 25 cents above the Tonic. These intervals are little more than stepping stones in modulation, and extra intervals that can be used together with the Tonic for a sense of dissonance, or for a slightly less resolved version of a Unison or Octave. | '''Supercommatic''' - This is a note that occurs at intervals from about 3.5 cents to roughly 25 cents above the Tonic.

'''Geminodominant''' - This is a note that occurs roughly at intervals ranging from about 25 cents to about 3.5 cents short of the 3/2 perfect fifth in the scale's direction of construction. Although often overlooked or even outright shunned by traditional theorists, the Geminodominant is a legitimate diatonic function in terms of this analysis- albeit one only existing in non-meantone environments in which it is easily derived from the Dominant through detempering, occurring in [[5-limit]] diatonic environments, and acting as a sort of "fraternal twin" to the Dominant, hence its name. Specifically, as typified by intervals like [[40/27]], Geminodominants are dissonant intervals that simultaneously act as alternatives to the Dominant in both chord progressions and chord construction, and often require resolution, though they also have a Preserviant function. The dissonance of this function relative to a chord root is useful in preventing tonicization of chords built on the traditional weak harmonies- the Mediant and the Contramediant- which also has the benefits of strengthening interrupted cadences and creating the sense of impending movement, but outside of these usages and well supported chords, this kind of thing is best avoided since things repel the similar but not identical. Apart from diatonic contexts, Geminodominants only rise to prominence in systems where what might otherwise function as a Dominant is found just short of the sweet spot range near the standard issue 3/2. | '''Geminodominant''' - This is a note that occurs roughly at intervals ranging from about 25 cents to about 3.5 cents short of the 3/2 perfect fifth in the scale's direction of construction.

'''Geminoserviant''' - This is a note that occurs roughly at intervals ranging from about 3.5 cents to about 25 cents beyond the 4/3 perfect fourth in the scale's direction of construction. Although often overlooked or even outright shunned by traditional theorists, the Geminodominant is a legitimate diatonic function in terms of this analysis- albeit one only existing in non-meantone environments in which it is easily derived from the Serviant through detempering, occurring in 5-limit diatonic environments, and acting as a sort of "fraternal twin" to the Serviant, hence its name. As typified by intervals like [[27/20]], Geminoserviants are dissonant intervals that often act as a sort of predominant and or as the inverses of Geminodominants. The dissonance of this function relative to a chord root is useful in preventing tonicization of chords built on Mediant and the Contramediant, but outside of these usages and well supported chords, this kind of thing is best avoided.
