This pattern of the scale is another popular form used by many players. This form and the 2nd form have very similar patterns.
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.
