French Harmony: using logic for a deceptive cadence (root position chords) #harmony

Added: 2026-05-16

[00:00:00]When to use a deceptive cadence? For this soprano exercise, we found the first chord and the half cadence. Now we must decide what happens afterwards. We see the G, so the only possibilities are one, four, and six.

[00:00:12]The one is a no-go as it forms a perfect authentic cadence, which ends the exercise. The four is a no-go because we cannot have the same harmony two chords in a row.

[00:00:23]Therefore, we must use the deceptive cadence.
