Hugging. Do you like doing it? Do you do it often? I’m not the touchy-feely type so I only hug if the other person initiates it first. And even then, the whole thing seems really weird to me.
Emotional rescues. I prefer my classical musicians to not have seizures on stage. When I was still taking lessons, I’ve had piano teachers tell me to express more emotion while playing–but I wasn’t about to go flapping about on the keyboard. My view of performance is similar to that of the author of the article. Emotional music can simply be portrayed by how it is played and not by physical and functionless gestures.
Addendum: And if people need physical cues to tell them how to feel at a particular passage in a piece of music, they’ve missed the point entirely.
