That's like a program transposing while someone's playing normally. That would take some work to actually play that. Nice for an exercise though.
Oh, I see.... This youtubers added in on afterward. I wonder what the original sounds like. Acapella then originally?
Found it without accompaniment added.

I mean the audience sounds like they have the usual audience pitch center.
I was going to say avante garde, but this sounds more like an exercise. I've done this for conducting -- Take a standard, very well-known, piece, but change the meter around a lot and conduct that. It messes with your mind.
