The blues scale formula is a fundamental concept every piano player should know. This sassy scale lets you riff, solo, and improvise as you play your favorite rock or blues songs!
The major blues scale formula is 1 – 2 – ♭3 – ♮3 – 5 – 6. Which means the C major blues scale consists of the notes C – D – E♭ – E♮ – G – A. The minor blues scale formula is 1 – ♭3 – 4 – ♭5 – 5 – ♭7, so the C minor blues scale has the notes C – E♭ – F – G♭ – G – B♭.
In this lesson, we’ll explain the theory behind the blues scale formula and show you all the major and minor blues scales in all 12 keys.

It will sound awesome!
