A Blues Scale: Minor and Major

A Blues Scale for Guitar: Master one of the most used guitar scales in all musical genres, with the Best Charts.

The Blues Scale is based on the minor pentatonic scale, with the addition of what is known as the Blue Note.

This note was introduced by African slaves brought to North America, for the creation of one of the most influential genres in the development of American popular music: The Blues.

The blue note became part of musical genres such as jazz, bluegrass, rhythm and blues, rock and roll, funk, pop, heavy metal, hip-hop, and country music. Representing the influence of African musical scales on North American popular music.

The note added to the minor pentatonic scale would be a diminished 5th, or augmented 4th. In other words, simply adding the note that is between the 4th and 5th degree of a minor pentatonic scale, we would obtain a Blues Scale. Also known as the minor pentatonic blues scale, or hexatonic blues scale.
