MPB plagal progression on cavaquinho
What is the MPB plagal progression?
The MPB plagal progression is C, F and C (I–IV–I), in the key of C major. Read as harmonic function it moves tonic → subdominant → tonic, 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) → F (IV, the stroll) → C (I, home). 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. This is the cavaquinho's true home: in samba, choro and pagode it is the rhythmic and harmonic center, driving the groove with bright, percussive chords. Its home chord C keeps its lowest note on E and rings 1 open string.
