C# Rock & Folk Classic
I – IV – V progression in C# major
C# Rock & Folk Classic — I – IV – V
The C# I–IV–V progression (C# – F# – G#) is the three-chord foundation of rock, country, and folk music. These three major chords provide maximum energy with minimum complexity. Adding sevenths (C#Maj7 – F#Maj7 – G#7) gives it a bluesy edge.
