I consider there to be four main sonorities:

	Major, Minor, Super, and Sub. While there are triads for these, they generally sound more interesting and distinct as tetrads. Major tetrad is of course 4:5:6:7 while minor is 10:12:15:17, Super is 14:18:21:27 and Sub is 6:7:9:11. Now while obviously these chords don't all exist in the same temperament universe, I consider them all to be consonant resolved sonorities. Some argue that 14:18:21:27 is not a consonant tetrad but it is as it's built from perfect fifths just like the other three.

	There are a huge amount of dissonant chord possibilities in 22 EDO and each one demands testing and experimentation. The most useful thus far in my explorations is the major Super Seventh chord which is basically a major triad with a super seventh. So if 4:5:6:7 is a tonic tetrad then this chord would be the septimal version of a dominant chord. If we play a F major tetrad as the tonic then I think a Bb Major Super Seventh chord works very well for the dominant. Because of voice leading, the dominant like chord is on the fourth not the fifth in this case.

	Another interesting chord is the magic seventh chord which may be seen as the septimal or higher limit version of a diminished chord. Let's say perhaps we take our Fh7 chord again and contract it to a F7 chord (F Magic Seventh), we then get a movement of the 5/4 turning to 6/5, 3/2 moving down to a 16/11, and the 7/4 remains as a common tone. This magic seventh chord could be used with Super seventh chords as well if we started from a F super seventh chord and moved to a F7 it would be 9/7 moves down to 6/5, 3/2 again to 16/11, and 27/14 moving to a 7/4.

			Basically, just as people a long time ago stopped using only perfect fifths and began to find thirds as consonance, I feel that the 10 step or 11/8 interval should be considered a new point of restful consonance. Because porcupine tends to be undecimal like, it's a gateway to using the 11th harmonic and subharmonic within 5 limit structures. It's about as </pre></div>

	Basically when a BbMS7 resolves to an Fh7 (F Harmonic Seventh), we end up with a inward motion of a dissonant 9/7 resolving to a more consonant 7/5. The Super seventh in the Bb chord creates powerful small step voice leading with resolves to the Fh7 tonic. Chances are, this may not work with minor tetrads but I'm not entirely sure yet.<br />		Basically when a BbMS7 resolves to an Fh7 (F Harmonic Seventh), we end up with a inward motion of a dissonant 9/7 resolving to a more consonant 7/5.

	Another interesting chord is the magic seventh chord which may be seen as the septimal or higher limit version of a diminished chord. Let's say perhaps we take our Fh7 chord again and contract it to a F7 chord (F Magic Seventh), we then get a movement of the 5/4 turning to 6/5, 3/2 moving down to a 16/11, and the 7/4 remains as a common tone. This magic seventh chord could be used with Super seventh chords as well if we started from a F super seventh chord and moved to a F7 it would be 9/7 moves down to 6/5, 3/2 again to 16/11, and 27/14 moving to a 7/4. <br />		Another interesting chord is the magic seventh chord which may be seen as the septimal or higher limit version of a diminished chord.
