The pentatonic scales are often a guitar player's best friend, and the more of them you learn, the better off you'll be. This minor variation of the pentatonic is a bit more straightforward than some of the others, as all notes fall within four frets.
For a quick review you can check the Pentatonic Major Scale if you feel like you need to. Otherwise the structure of this scale is fairly straightforward and simple.
The placement of these notes makes things very easy on you. Make sure you approach this scale (and others) in the following manner:
1. Learn and memorize the pattern.
2. Memorize the sound and the note spacing.
