What are the primary conditions concerning the IRREGULAR resolutions of the following harmonies in common practice music?:

-Dominant chords

-Auxiliary Seventh chords (chords of sequence)

-Diminished seventh chords

-Minor seventh chords

-Ninth chords

From what I've read, the dominant can resolve to various other keys, but on the whole, the dissonant tones present should resolve to a different degree due to the motion inherently created by all dissonant harmonies.

One example of such a resolution (in four parts) is when a dominant seventh in first inversion with the soprano as the fifth scale degree, and the alto as the fourth degree, resolve to another dominant seventh constructed upon the original key’s leading tone. Some other examples are shown below:enter image description here

Some explanations for these occurrences (most notable in the romantic idiom) are sometimes explained by theorists as appearing through voiceleading tendencies, an incomplete harmonic system, or extended tonality. (this term is to be clarified later).

    where did you read? "the dominant can resolve to various other keys" that and your wording about dissonance don't seem like what you will read in a good harmony textbook – Michael Curtis Apr 22 at 13:50

    @Laprtsenia -- I'm not sure who that comment is aimed at, but when commenters express confusion or seem to miss your point, you might consider that your question could do with some clarifications instead of leaving barbed comments. "... the dominant can resolve to various other keys,...." Not sure what you mean here; dominant harmonies resolve to other harmonies, not other keys, but maybe you are talking about pivot chords? In any case, asking about "the primary conditions concerning... resolutions..." of five different chord types seems too broad to me for this site. – David Bowling Apr 23 at 2:03
