Ah yes, the ever-glorious high note.
Every time we sing scales and warm up, at the end, the boys in our show choir, no matter what, skip an octave up. Some voices crack, some sing nicely, and others are straight-up SCREECHING.
They also occasionally dance a little during our round/cannon warm-ups.
I've tried doing it a little too, but my friends, who keep me from going insane, stop me.
Thank you, friends.
