Music is motion... tonal motion... chordal motion.
Fixing a scale, then, suggests fixating, in an otherwise too fluid medium, a kind of stepping-stone pathway of exact ratios upon the void. - A pattern of orderly steps.
The ratios themselves constitute an all-important instrument for order.
There are benefits to composing patterns, from the smallest element outwards, from the center and not from the fringe, both for optical and aural composition.
