Samba · ii-V-I — Cavaquinho

What is the Samba · ii-V-I progression?

The Samba · ii-V-I progression is Cm → F → A# (ii – V – I), in the key of Bb. Read as harmonic function it moves subdominant → dominant → 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: Cm (ii, the stroll) → F (V, time to come back) → A# (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 A# — the home chord.

Cavaquinho

Its chords sound tight and punchy; instead of holding long shapes, it keeps the beat moving with short, repeated strums. 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 A# keeps its lowest note on F.
