The Major Blues Scale | Guitar Lesson with Shapes

What is The Major Blues Scale?

The major blues scale is one of the most important blues scales to know. It is built with root (1), second (2), minor third (b3 - passing tone), major third (3), fifth (5) and sixth (6). The major blues scale  is a useful device when you want to improvise over major and dominant chords. It gives bluesy vibes to your guitar solos.

How Is Built The Major Blues Scale?

This is a hexatonic scale, it means that it contains six notes per octaves just as the minor blues scale. In comparison with the major pentatonic scale, there is an additional note between the second (2) and the major third (3).

This note is named flat tenth (b10) or flat third (b3), this a blue note. Flat tenth is more appropriate in this harmonic context because a scale can't have two thirds in its composition. 

In brief the major blues scale is made up of : root (1), major second (2), a flat tenth (b10) or minor third (b3), major third (3), fifth (5) and sixth (6).
