Module 25 — Blues: Form, Language, and Piano Vocabulary

Blues is important because it breaks one assumption we've used a lot so far:

not every note has to “fit” the chord in the clean classical sense.

Blues often deliberately mixes major and minor color over dominant harmony.

The core sound comes from tension like:

♭3 → 3

and:

♭5 → 5

combined with repetition, rhythm, call-and-response, and the 12-bar form.
