Folk · axis — Cavaquinho
What is the Folk · axis progression?
The Folk · axis progression is G → D → Em → C (I – V – vi – IV), in the key of G. Read as harmonic function it moves tonic → dominant → tonic → subdominant, cycling as a vamp with no full 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: G (I, home) → D (V, time to come back) → Em (vi, home) → C (IV, the stroll). 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 G — the home chord.
Cavaquinho
Its chords sound tight and punchy; instead of holding long shapes, it keeps the beat moving with short, repeated strums. Outside Brazil the cavaquinho is a newcomer to these styles, but its short, percussive strums fit reggae's off-beat chop nicely and add a thin, bright layer. Its home chord G keeps its lowest note on G.
