Starting with the kind of growl that singers like Bono use relatively
effectively to lead up to a note in a pop song - a la, " slight of hand
and twist of fate, on a bed of nails she makes me wait," but that can
be used to egregiously ill-effect, a unit of measurement should be
standardizes the effectiveness of these vocal
growls. I have the feeling that this will be both hard to do and
interesting, because 1. It is a standard technique, 2. It feels
effective to me at some times and other times grossly ineffective,
and, 3. some other people don't agree with me about the
effectiveness of specific examples of this vocal growl technique -
which makes me think that it is not just aesthetics and opinion going
on here but a specific kind of hearing blindness/hyper-sensitivity
that is clouding the possibility of standardization of agreement on
the effectiveness of these vocal growls.
Eventually this kind of measurement could be used to score and then
optimize what will surely turn into purely a vocal musical genre.

shape of pitch over time, clicks per second, things like
that. And as to the genre, there is already a pretty
extensive collection of YouTube videos on, "how to growl",

YT videos, it seems that growl /fry type
