Building and Resolving Diminished 7th Chords
Cheat Sheet
A vii°7 chord is made up entirely of stacked minor 3rds. It is not found naturally
in a major key (an accidental must be added). It is found naturally in a minor
key when built on the raised 7th scale degree.
vii¯7
A
chord is made up of a m3+m3+M3, and is found naturally when built on
the 7th scale degree of a major key or the second scale degree of a minor key.
Both of these chords can be used as a substitute for the dominant.
(notice how there is only one note difference between V and vii°7...that's why they are
good substitutes)

To resolve a diminished 7th chord, the leading tone (which is the root) must resolve
up. The rest of the chord members resolve down. There is a little flexibility with
the third of the chord to resolve up if needed.
Be careful with half-diminished - you
can end up with parallel fifths. If you have
a fifth between the 3rd and 7th, resolve
the 3rd up to avoid it.
Leading tone up, everything else down.
