G 12 Bar Blues — I – I – I – I – IV – IV – I – I – V – IV – I – V
The G 12 Bar Blues progression (G – G – G – G – C – C – G – G – D – C – G – D) 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 (GMaj7 – GMaj7 – GMaj7 – GMaj7 – CMaj7 – CMaj7 – GMaj7 – GMaj7 – D7 – CMaj7 – GMaj7 – D7), it delivers the authentic blues sound.
