Section 9.8 The i–VII–VI–VII Progression
The \(\left.\text{i}\right.\)–\(\left.\text{VII}\right.\)–\(\left.\text{VI}\right.\)–\(\left.\text{VII}\right.\) (\(\left.\text{A}\text{m}\right.\)–\(\left.\text{G}\right.\)–\(\left.\text{F}\right.\)–\(\left.\text{G}\right.\)) progression is similar to the descending \(\hat{1} \) –♭\(\hat{7} \)–♭\(\hat{6} \)–\(\hat{5} \) bass line of the “Andalusian progression” (\(\left.\text{A}\text{m}\right.\)–\(\left.\text{G}\right.\)–\(\left.\text{F}\right.\)–\(\left.\text{E}\right.\)) in flamenco music, with the exception of the last bass note or chord.
Here are examples of the \(\left.\text{i}\right.\)–\(\left.\text{VII}\right.\)–\(\left.\text{VI}\right.\)–\(\left.\text{VII}\right.\) progression.
The \(\left.\text{i}\right.\)–\(\left.\text{VII}\right.\)–\(\left.\text{VI}\right.\)–\(\left.\text{VII}\right.\) progression can also be rotated to become \(\left.\text{VI}\right.\)–\(\left.\text{VII}\right.\)–\(\left.\text{i}\right.\)–\(\left.\text{VII}\right.\).
In some cases, the fourth chord is eliminated. In that case, \(\left.\text{VI}\right.\)–\(\left.\text{VII}\right.\)–\(\left.\text{i}\right.\)–\(\left.\text{VII}\right.\) becomes \(\left.\text{VI}\right.\)–\(\left.\text{VII}\right.\)–\(\left.\text{i}\right.\)–\(\left.\text{i}\right.\), as in the following examples.
The \(\left.\text{i}\right.\)–\(\left.\text{VII}\right.\)–\(\left.\text{VI}\right.\)–\(\left.\text{VII}\right.\) progression can also be thought of as being in a major key: \(\left.\text{vi}\right.\)–\(\left.\text{V}\right.\)–\(\left.\text{IV}\right.\)–\(\left.\text{V}\right.\).
There are several more common harmonic progressions to explore in future chapters dealing with topics like secondary chords, mode mixture, the Neapolitan chord, augmented sixth chords, and jazz harmony.
