12. The subtonic triad (VII) can be used to harmonize a melody that includes the subtonic tone. The subdominant chord normally follows the subtonic triad. This has the effect of a passing chord (Figure 7-26).

13. The subtonic triad can also resolve to the III triad in root position. The lowered seventh scale degree (root of the subtonic triad) functions as a dominant of the mediant (Figure 7-27).
