What is the Blues · quick-change progression?
The Blues · quick-change progression is E → A → E → E (I – IV – I – I), in the key of E. Read as harmonic function it moves tonic → subdominant → tonic → tonic, 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: E (I, home) → A (IV, the stroll) → E (I, home) → E (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 E — the home chord.
Guitar
On the acoustic guitar you hold the whole song in your hands: the low sixth string lays down a bass note while the higher strings build the chord above it. From campfire pop to rock ballads and blues, the acoustic guitar is the default choice, whether you strum full chords or pick out a quiet verse. Its home chord E keeps its lowest note on E and rings 3 open strings.
