octave rocking
When singers try to scream up, down, and back up again on one note like they're trying to rip their vocal cords out just to make the national anthem sound like a horror movie.
"I tried to do an octave rock on 'America the Beautiful' and I sounded like a dying goat.", @SingerRocks
"During the national anthem at the Super Bowl, the singer did an octave rock so bad, the crowd started chanting 'just give us the flag.'", @FootballFanatic
My cousin tried an octave rock during the Memorial Day parade and now his voice is stuck in a war zone.", @FamilyDrama
