A# Rock & Folk Classic
I – IV – V progression in A# major
A# Rock & Folk Classic — I – IV – V
The A# I–IV–V progression (A# – D# – F) is the three-chord foundation of rock, country, and folk music. These three major chords provide maximum energy with minimum complexity. Adding sevenths (A#Maj7 – D#Maj7 – F7) gives it a bluesy edge.
