Justin teaches us how to play the minor pentatonic scale in this tutorial. This is a useful scale that you will use as long as you play the guitar. Start with your first finger in the fifth fret of the thickest string. Play A, then reach up with your fourth finger in the eight fret. All fingers should be in ascending order with the different frets. Move onto the next string, playing first finger and third finger. Go onto the next string with the fingers changing in between the frets as you go. Continue to do this until you have finished with all the different frets and then try going faster as you go to learn these better!
