Smooth shifts, bow speed, contact point, distribution, quality and concept of sound, and much, much more. It’s an opportunity to strip away the dozens of other variables we would otherwise encounter in a piece of music, and focus on mastering just one aspect of our technique in isolation. Then adding in the others, one at a time, to see how that changes things. So that we can tweak and experiment with the little tiny details and truly master the fundamentals."
