Okay kids, this is where it all starts! The major scale modes! You’ve probably seen around the internet, in books and many other resources that there is other ways to play these scales. In fact, any scale. We would highly suggest to avoid playing your scales in a non 3nps (or 4nps) way.
3nps scales make things very easy and give you the most mileage of notes. ‘Cowboy’ shapes can be very confusing because of the varying number of notes per string. The 3nps shapes make it nice and easy to string things together and quickly navigate the fretboard.
