The passing vii°6 is very similar the passing 6/4, differing from each other only by one note: When moving from I to a passing vii°6, scale degree 5 drops by step to a neighbor tone. See above left. However when I moves to a passing 6/4, scale degree 5 remains on the same pitch. See above right. Playing the music in the illustration above shows that these two passing chords can be difficult to distinguish.
To distinguish the two passing chords by ear, listen for a more intense dissonant sound, due to the tritone, in vii°6, and a plainer major sound in V6/4. In the following pairs of chord progressions which one, in column A or B, has the passing vii°6 and which one has the passing V6/4?
