Interactive piano keyboard showing C# Blues scale degrees. Click highlighted keys to play.
The C♯ blues scale (C♯, E, F♯, G, G♯, B) is an uncommon but powerful scale for jazz and rock soloing in sharp keys. The added blue note G creates expressive tension between the F♯ and G♯, enabling chromatic bends and slides. It works over C♯ minor progressions in rock and fusion contexts.
Adding the flat 5th (the “blue note”) to minor pentatonic creates the characteristic tension-and-release of blues improvisation. This tritone is the single interval that gives the blues scale its soulful, crying quality.
The diatonic chords in C# Blues are: C#m, Em, F#m, G, G#m, Baug. These are the chords built naturally from each degree of the scale.
