Alright something really weird for a vocal question. I am a bass/baritone and my range is around f2-e4. But I can do this really f**kin' weird thing where i compress my vocal chords and sing around an d5 from my chest (It's positively not falsetto). But it sounds like a grandpa getting his prostate removed. It doesn't really hurt me, but once i almost fainted when i did it (like blood rushed all to my head). Is this bad for my voice?

OMG, this sounds so stupid but thanks for any answers!
Doesn't sound like its bad for your voice. The fainting is to do with breath control.

there is a vocals section of the forums though
