* What exactly is people's definition of the MetalScream? Does one even exist? [[http://www.youtube.com/watch?v=fHo5w2WGZWA This is not a Metal Scream]]. Corey Taylor is not capable of type 1, Axel Rose isn't noted for projection or volume and Kurt Cobain and James Hetfield just shout a lot. [[http://www.youtube.com/watch?v=537hCRIhQKw#t=50s This is a Metal Scream]]. [[http://www.youtube.com/watch?v=0xyxtzD54rM#t=2m26s This is also a Metal Scream]].
** Judging the level of "metal" in a scream or emphasized vocal exclamation is really very subjective, and there's honestly no hard rule on what defines one, other than being loud and sustained.
** Is this really a trope we can call subjective? Volume, projection, sustain, those seem like pretty hard and fast requirements. As I said above, many of these examples lack this (as far as I see it, shouting aggressively using the speaking voice in a way that harms the vocal chords is CarefulWithThatAxe). Thankfully someone made an article on HarshVocals, so this article can be further distilled.
