Jazz rhythm changes (A section) progression on cavaquinho
What is the Jazz rhythm changes (A section) progression?
The Jazz rhythm changes (A section) progression is C, Am, DmDmDmDm and G (I–vi–ii–V), in the key of C major. Read as harmonic function it moves tonic → tonic → subdominant → dominant, arriving home on a cadence. Play one chord per bar and let it loop.
Play any song you love and it does this: leaves home, takes a walk, and at the right moment somebody yells "come back!". This progression is that route, road sign by road sign: C (I, home) → Am (vi, home) → Dm (ii, the stroll) → G (V, time to come back). Hit play and follow with your finger on the names — when you reach the chord marked "time to come back", notice your own body waiting for C — the home chord.
Cavaquinho
The cavaquinho is a small, bright four-string with no low bass, so it fills the upper-middle range and leaves the deep notes to others. Jazz isn't its usual room, but choro trained the cavaquinho for rich, colorful chords, so it can back a swing tune with a light, chopping bounce. Its home chord C keeps its lowest note on E and rings 1 open string.
