A Blues Scale on Piano

The A Blues scale sounds gritty and vocal. It runs A – C – D – Eb – E – G and is written with one flat.

It shares its key signature with C major, its relative major.

Interval Circle

W+HWHHW+HWCb3DbD4Ebb5E5FGbGb7AbA1BbB

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

Why this fingering

One black key (Eb) sits in this scale, and the thumb has to avoid it. In the right hand the thumb crosses under onto E; 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.
