You know how their faces contort when hitting certain notes or rhythms? Why is that triggered in the face? Is it an emotional response? Communication by facial expression? Vestigial from some other process?

I believe the term you’re looking for is “stank face”. I’ll sometimes do this when I’m listening to a song and a part is especially virtuosic or surprising. When you see a musician doing it it’s often either concentration or them hitting sort of a flow state where they’re really feeling what they’re playing.
