If a chord is [[dyadic chord #Essentially tempered dyadic chord|essentially just]], then it is classified as [[otonal]] if it is best analyzed in terms of the [[harmonic series]], [[utonal]] if best analyzed in terms of the [[subharmonic series]], and [[ambitonal]] if it is equally well analyzed with either. If a chord is [[dyadic chord #Essentially tempered dyadic chord|essentially tempered]], it is classified based on which [[comma]]s are needed to define the chord. Chords essentially tempered by [[50/49]] are labeled [[jubilismic chords|jubilismic]], by [[64/63]] [[archytas chords|archytas]], by [[99/98]] [[mothwellsmic chords|mothwellsmic]], by [[100/99]] [[ptolemismic chords|ptolemismic]], by [[176/175]] [[valinorsmic chords|valinorsmic]], by [[225/224]] [[marvel chords|marvel]], and by [[896/891]] [[pentacircle chords|pentacircle]]. Chords that require any two of 50/49, 99/98, and 100/99 to vanish are labeled [[undecimal jubilismic chords|jubilismic11]]. Chords that require any two of 64/63, 100/99, and 176/175 to vanish are labeled [[ares chords|ares]].

Typing the chords requires consideration of the fact that pajara conflates several pairs of consonances: [[11/10]]~[[10/9]], [[9/8]]~[[8/7]], [[14/11]]~[[9/7]], [[7/5]]~[[10/7]], and their octave complements. If a [[transversal]] can be found which shows the chord to be essentially just, that transversal is listed along with a typing as otonal, utonal, or ambitonal. However, sometimes multiple such transversals exist, in which case the chord is a [[plurichord]], and the type is given for all possible interpretations. If the chord is essentially tempered, it is analyzed in terms of the transversal that requires the minimum amount of commas to be tempered out | Typing the chords requires consideration of the fact that pajara conflates several pairs of consonances: [[11/10]]~[[10/9]], [[9/8]]~[[8/7]], [[14/11]]~[[9/7]], [[7/5]]~[[10/7]], and their octave complements.

If the chord is essentially tempered, it is analyzed in terms of the transversal that requires the minimum amount of commas to be tempered out. If there is a tie between multiple transversals, then the types are prioritized as follows: jubilismic > archytas > marvel > mothwellsmic > ptolemismic > valinorsmic > pentacircle, and jubilismic11 > ares > apollo. | ||
In the "Generators" column of the tables below, each number corresponds to a note of the chord, with the number shown being the number of perfect fifths which need to be stacked above the root or semioctave to reach that note. If an apostrophe follows the number, then the note is reached by stacking fifths above the semioctave; if no apostrophe follows the number, then the note is reached by stacking fifths above the root. For example, the note '''3''' is reached by stacking three fifths above the root, which in pajara is equal to [[12/7]] when octave reduced. The note '''3'''' is reached by stacking 3 fifths above the semioctave, which in pajara is [[6/5]] when octave reduced. | In the "Generators" column of the tables below, each number corresponds to a note of the chord, with the number shown being the number of perfect fifths which need to be stacked above the root or semioctave to reach that note.
