C 12 Bar Blues — I – I – I – I – IV – IV – I – I – V – IV – I – V
The C 12 Bar Blues progression (C – C – C – C – F – F – C – C – G – F – C – G) is the universal foundation of the blues. Using only three chords over twelve bars, it has generated more classic songs than any other form. With dominant sevenths (CMaj7 – CMaj7 – CMaj7 – CMaj7 – FMaj7 – FMaj7 – CMaj7 – CMaj7 – G7 – FMaj7 – CMaj7 – G7), it delivers the authentic blues sound.
