C Major Blues Scale

The C Major Blues Scale is a variation of the regular major scale that introduces the "blue note"—a note that creates a bluesy or soulful sound. In a major blues scale, the "blue note" is typically the augmented 3rd (or flatted 3rd in some cases) or flattened 5th. 

C (root)
D (major 2nd)
E♭ (augmented 3rd or "blue note")
E (major 3rd)
G (perfect 5th)
G♯ (augmented 5th or "blue note")
A (major 6th)

Example:
C – Root note.
D – Major 2nd.
E♭ – The "blue note" or flattened 3rd, which gives the scale a bluesy feel.
E – Major 3rd (this note is used in the typical major scale, but the blues scale includes both the major 3rd and the "blue" note—E♭—for the expressive effect).
G – Perfect 5th.
G♯ – Augmented 5th or "blue note", which adds a harmonic tension, contributing to the bluesy sound.
A – Major 6th.
C – Return to the root note.

Uses of  the C Major Blues Scale:
The scale is used in blues, jazz, and rock music to give a light, melodic feel while still incorporating some "bluesy" tension.
When playing, the E♭ and G♯ are the notes that create the "blue" sound in this scale, as they bend the harmony of the traditional major scale to introduce an expressive.

Comparison with the C Major Pentatonic Scale:
The C Major Blues Scale is similar to the C Major Pentatonic Scale but with the addition of the blue notes (E♭ and G♯). Here's how the two compare:

C Major Pentatonic Scale: C, D, E, G, A
C Major Blues Scale: C, D, E♭, E, G, G♯, A


You can use the C major blues scale over a typical C major chord progression to add flavor and expression. For example, in a 12-bar blues progression in C major, you might use the scale to solo or create melody lines that emphasize those "blue" notes (E♭ and G♯) to make the sound more soulful.

The C Major Blues Scale is C, D, E♭, E, G, G♯, A.
The "blue notes" (E♭ and G♯) create a characteristic "bluesy" sound while still being based on the major scale.
This scale is a great tool for adding an emotional and expressive flavor to major key blues music!
