27.4 The Special Resolution of vii∘7 (and viiøø7)

��

The viivii∘7 and viiøviiø7 chords consist entirely of tendency tones (7^ , 2^ , 4^ , 6^ ). If one resolves all of those tendency tones correctly (2^ –1^ , 4^ –3^ , 6^ –5^ , 7^ –8^ ), one might write parallel 5ths depending on the voicing of the viivii∘7 and viiøviiø7 chord. Therefore, be sure to memorize the following principle:

��

Principle 27.4.1. Resolving viivii∘7.

When the 7th of a viivii∘7 or viiøviiø7 chord is voiced above the 3rd of the chord, resolve the 3rd of the chord (scale degree 2^ ) up by step while resolving all other tendency tones normally (4^ –3^ , 6^ –5^ , 7^ –8^ ).

��

The third measure above shows that revoicing the chord is another solution, since parallel 4ths are not objectionable in this situation.

��

If the 7th of the chord is voiced below the 3rd of the chord, resolve all tendency tones normally.
