There is not a "heavy metal" scale. Not a "country"
scale. But there is a blues scale on the guitar. And this blues scale is not
just used in blues music. But it will definitely add a bluesy
sound to what ever style you plug it into.
A blues scale is nothing more than a minor pentatonic scale with
an added note. That added note is sometimes referred to as the
"blue note". That particular note creates a certain
amount of tension that is a common sound in the blues.
Below is a basic minor pentatonic scale form, and then that same
form with the addition of the "blue note".....appropriately
show the suggested fingering
= Scale root
= Added blue
The blues scale only consists of 6 different note names. But
when playing a blues scale on the guitar you are going to play
more than just 6 notes. You are going to play all of the possible
places for those 6 notes within one position.
A C blues scale consists of the notes C
E F G
G and B.
Below are the names of all of the notes in a basic C blues scale
So keep in mind as you play the other blues scale forms found
in this lesson, they will not neatly start and end on the root
of the scale. They are just forms that cover all of the note possibilities
in an entire position.
