It is the bedrock of most blues guitarists solos and the reason is most obviously the sound it creates but it is also extremely easy to learn and is the first scale I teach any student who has an interest in the blues and soloing.
Replacing the major 3rd and 7ths with their flattened cousins gives the scale it’s unique sound.
The amount of simple bluesy licks that can be formed with these 5 notes is endless.
Many of the greatest guitarists have relied on this scale for their soloing including Clapton Page and Angus Young.
The scale fits perfectly under the fingers and is easily moveable up and down the fretboard.
Clapton builds his solos around the minor pentatonic scale throwing in a few notes only he can find!
