G Blues Scale on Piano

The G Blues scale sounds gritty and vocal. It runs G – Bb – C – Db – D – F and is written with two flats.

It shares its key signature with Bb 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.

Why this fingering

2 black keys (Bb, Db) sit in this scale, and the thumb has to avoid them. In the right hand the thumb crosses under onto D; 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.
