The viio7 and viiø7 - Doubling and Resolving

Question 1

the viio7 chord

Answer 1

• what we find in major keys has a tritone on bottom with a m7th interval
• • the diminished fifth happens twice in a viio7 chord and is the reason for the dissonance
• • an augmented forth is the inverted interval of the diminished fifth
• resolving viio7 chords:
• • the root of the chord likes to resolve up to the tonic (7 to 1)
• • the 5th of the chord likes to resolve down to the submediant (4 to 3)
• • the 7th of the chord resolve down to the dominant (6 to 5)
• • the 3rd of the chord likes to resolve to submediant or the tonic depending on chords (2 to 1 or 3)
• • with parallel tenths rule can allow for different resolutions to avoid other bad part writing errors
• leading tone chords can be found in root position, first (), second () and third inversion ()
• • first and second inversion viio chords resolve to the second inversion tonic chord
• • third inversion si rare because the bass will resolve to the second inversion tonic chord
• the viiø7 chord is what we find in major keys we have a tritone on bottom and top with a d7th interval
