=== Rising Ultra ===

The Rising Ultra triad is a triad which consists of the Root, the 450c Ultra third on top of that, and the 300c Minor third on top of that.  When this triad is built on the note located 650 cents above the Tonic, it can act as a set-up for either a Falling Major triad or Falling Neutral triad built on the root located a semitone below it.  In addition, it can also be followed up by a Falling Major or Falling Minor triad built on the Tonic, which in turn can lead to modulations.

=== Rising Major ===

One of four chords named for a similar type of chord found in [[Oneirotonic]] scales, the Rising Major triad is a bright but tense triad which consists of the Root, the 400c Major third on top of that, and the 350c Neutral third on top of that.  When built on the Tonic, it can lead into modulations.

=== Rising Neutral ===

The rising Neutral triad is a triad which consists of the Root, the 350c Neutral third on top of that, and the 400c Major third on top of that.  It can also set up either a Major triad or a Falling Major triad built on the root located a major third below it, and can also lead into either a Major or Minor triad on the same root.

One of four chords named for a similar type of chord found in Oneirotonic scales, the Rising Minor triad is a triad which consists of the Root, the 300c Major third on top of that, and the 450c Ultra third on top of that, though it can also be conceived as being the result of stacking two 750c Fifths.  It is likely to arise in counterpoint under certain circumstances.  Like a Rising Neutral triad, it can set up either a Major triad or a Falling Major triad built on the root located a major third below it.  However, in addition to this, has some of the same set-ups and follow-ups as the Rising Ultra triad.

=== Falling Major ===

One of four chords named for a similar type of chord found in Oneirotonic scales, the Falling Major triad is a bright but tense triad which consists of the Root, the 400c Major third on top of that, and the 250c Infra third on top of that.  When this triad is built on the note located 550 cents above the Tonic, especially with octave reduplication of the root, it can easily be followed up with with the same Tonic's traditional V7 chord.  In modulation, this same triad can also be followed up with a Dominant seventh chord built on the same root, leading to the tonicization of the neutral seventh.  Regardless, the use of this chord requires the proper harmonic and melodic set-ups, with two possible harmonic set-ups being the III Minor triad and the I Major triad of a Major tonality.

=== Falling Neutral ===

The Falling Neutral triad is a triad which consists of the Root, the 350c Neutral third on top of that, and the 300c Minor third on top of that.  It is one of two triads that can be considered to sound like a Xenharmonic version of a Diminished triad.  Like with a Falling Major Triad, it can easily be followed up with with the same Tonic's traditional V7 chord.

=== Falling Minor ===

One of four chords named for a similar type of chord found in Oneirotonic scales, the falling minor triad is a triad which consists of the Root, the 300c Minor third on top of that, and the 350c Neutral third on top of that.  It is also one of two triads that can be considered to sound like a Xenharmonic version of a Diminished triad.

=== Falling Infra ===

The Falling Infra triad is a triad which consists of the Root, the 250c Infra third on top of that, and the 400c Major third on top of that.  Like the Falling Major triad, when this triad is built on the note located 550 cents above the Tonic, especially with octave reduplication of the root, it can easily be followed up with with the same Tonic's traditional V7 chord.  However, the use of this chord also requires the proper set-ups in terms of both melody and harmony, with two possible harmonic set-ups being the Flat-VI Major triad and the I Minor triad of a Minor tonality.
