The Blues Scale

The Blues Scale is built on top of the the five note Pentatonic scale with the addition of the ‘blues note’ which provides a distinct blues sound.

  • The blues note within the major Blues scale is located between the 2nd and 3rd scale degrees, and is labelled as a ♭3.
  • The blues note within the minor Blues scale is located between the 4th and 5th scale degrees, and is labelled as a ♭5.

The examples below illustrate the relative minor of G major is E minor and the relative major of E minor is G major.
