This version of the major scale has 3 notes per string which makes alternate picking easier but the pattern stretches across the fretboard more. Make sure to use the correct fingering with the fret hand.
Scale Patterns are moveable scales where fingerings don't change from key to key. The root note (green dot) names the key of scale. What does this actually mean? It means you simply learn this pattern and you immediately know all 12 keys. You just need to place it on the correct fret to play the scale in a particular key.
