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 (C#Maj7 – C#Maj7 – C#Maj7 – C#Maj7 – F#Maj7 – F#Maj7 – C#Maj7 – C#Maj7 – G#7 – F#Maj7 – C#Maj7 – G#7), it delivers the authentic blues sound.
