  5. Dm–G–C, or usually Dm7–G7–Cmaj7
  6. Am–D–G, or Am7–D7–Gmaj7
  7. V–I, especially V7–I

The big idea from Module 5 is:

Harmony is motion between degrees of stability, not just a sequence of chord labels.

When you can hear home → preparation → tension → home, you are beginning to understand harmony by ear rather than merely calculate it.

Module 6 will take this one step further: cadences, phrase structure, harmonic rhythm, and how to recognize where a song is “punctuating” its musical sentences. This will start connecting theory directly to figuring out songs and accompaniments by ear.
