for a non-me example of what I'm talking about, the first half of this video is a performance of the first verse of an aria from "Julius Caesar in Egypt" by a mezzo and the second half is the same verse performed by a countertenor. At least for me, when I hear the first performance my brain goes "that middle aged woman sounds normal, so Caesar is a middle aged guy who sounds normal", in the 2nd my brain goes "this man is doing falsetto, so Caesar is a man doing falsetto ...why would he do that?"
