I wouldn't call it music.
@razie, how do you think ski performance would change if you saw different tipping of the right foot on the left footers? Personally, I don't see much difference in his ski performance right to left foot.

Interesting question. These asymmetries are not, I think, some element of technique that can be easily changed - these are normally compensations for something like an equipment misalignment. For instance, on the left footers, there should be less early ski engagement, but he's compensating on average with more early counter, so the engagement and performance is there... he knows how to get the ski to perform, that's for sure. When he's "on the power" they look quite symmetrical.
This one is subtle - to look at a simple example, let's take an example of a very strong alignment, where the skier is subconsciously leaning into the turn - I have encountered this quite frequently - the performance is often there, but the skier is at the maximum range of motion in that plane (and using smaller edge angles), having to bank away from every turn, to get the right performance - more prone to wiping out in off-camber turns or when skipping the rut on course or skidding on ice, as balance is impaired. It doesn't matter how much the coach yells at them, that's not something he/she can fix until the underlying problem is addressed. I have some very striking before/after examples with some of my racers... in video and results, from finishing less than half of races before fixing, to dropping over 30 points after fixing it.
