Blues Scale
The last of the three essential guitar scales in this article is the blues scale. It is similar to the minor pentatonic scale above but notice how each octave of the scale includes an extra extra note. This note sounds dissonant when you stay on it for too long. Therefore, use it as a passing note. You can hear the blues in the song I Can’t Quit You (Led Zeppelin). Below is the blues scale in E. Practice playing it slowly up and down.
