C# Blues Scale on Piano
The C# Blues scale sounds gritty and vocal. It runs C# – E – F# – G – G# – B and is written with three sharps.
It shares its key signature with E major, its relative major.
Interval Circle
All twelve semitones, root at the top. Filled dots are the notes of the scale, the outer numbers are their degrees, and W / H mark the whole and half steps between them.
About This Scale
The minor pentatonic with a chromatic passing note squeezed between the 4th and the 5th. That blue note is a decoration, not a destination — it works best slid through on the way somewhere else.
Fingering
Right Hand (ascending)
2-1-2-3-4-1-2
Left Hand (ascending)
2-1-4-3-2-1-2
Why this fingering
3 black keys (C#, F#, G#) sit in this scale, and the thumb has to avoid them. In the right hand the thumb crosses under onto E and B; let the elbow drift slightly outward as it passes rather than twisting the wrist.
The blue dots on the piano below show which keys to press — they turn green when you play the right note.
