A# 12 Bar Blues — I – I – I – I – IV – IV – I – I – V – IV – I – V
The A# 12 Bar Blues progression (A# – A# – A# – A# – D# – D# – A# – A# – F – D# – A# – F) 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 (A#Maj7 – A#Maj7 – A#Maj7 – A#Maj7 – D#Maj7 – D#Maj7 – A#Maj7 – A#Maj7 – F7 – D#Maj7 – A#Maj7 – F7), it delivers the authentic blues sound.
