What is the Mpb · IV ao iv progression?
The Mpb · IV ao iv progression is C → F → C (I – IV – I), in the key of C. Read as harmonic function it moves tonic → subdominant → tonic, arriving home on a cadence. Play one chord per bar and let it loop.
Good music works like a good walk: you leave, get a little lost on purpose, and come back. The map of this one: C (I, home) → F (IV, the stroll) → C (I, home). Press play and follow along — at the "time to come back" chord, notice the physical urge to hear C again — the home chord.
Electric guitar
The amplified tone holds each chord for a long time, so a few well-chosen notes keep ringing on their own while you leave room for the rest of the group. The electric guitar is not the traditional voice of samba or choro, but it fits MPB and modern arrangements well, adding smooth chords and quiet fills beside the core rhythm instruments. Its home chord C keeps its lowest note on C and rings 2 open strings.
