I think I got a decent grasp on producing pinch harmonics (when I do it in isolation, i.e. playing just one note, it comes out pretty reliably.)
I want to practice it within a musical context but I realized that I don't actually understand how do people decide to add pinch harmonics in their solo/phrasing.
What exactly is the pitch of a pinch harmonic sound? I am muting its fundamental frequency or the lower
n overtones, leaving the higher
n overtones to ring. Am I just producing X octaves higher note? Because pitch is a perception, we perceive a non-existing fundamental frequency if the overtones imply it.
If I apply it to a musical context, is there a possibility that I go out of key if I pinch it at the wrong spot on the string? My guess is no? What is the correct way to use this technique? What is it supposed to express?
Thanks for reading/answering
