Think of it like basic English... grammar is how you strum/finger stuff to make the words(notes) differentiate themselves but sound good together, but you can't even get to grammar without developing a basic vocabulary and "phonics" (no phonics debate prz).
Scales are that vocabulary and framework of understanding notes, and how they fit together.
