Narrow vs. Stretch

[Isaac OLEG SIMANOT]

Hello,

The term "projection", while not very representatives, means the same thing
my guess.

And yes I agree that having this bloom in the unisons make all the other low
rate intervals much easier to tune, as you focus on the same sensation and
don't care about the 6:3, 4:2, 8:4, etc.
