In music, an irregular resolution is resolution by a dominant seventh chord or diminished seventh chord to a chord other than the tonic. Regarding the dominant seventh, there are many irregular resolutions including to a chord with which it has tones in common or if the parts move only a whole or half step. Consecutive fifths and octaves, augmented intervals, and false relations should still be avoided. Voice leading may cause the seventh to ascend, to be prolonged into the next chord, or to be unresolved.
