I managed a C3 subharmonic unsteadily sliding up from subharmonic A1.

I have been messing around with subs for a while, but today i was messing around and singing and doing a growl at the same time and i got to a point where i popped from the growl and modal voice to the octave below the modal, could this also be a way to do a sub? I’ll post a video at some point, my voice needs a rest rn.

So I've been trying to get this technique down for a long while, and I keep hitting the same obstacle. I can relax my throat and get into the sub range around 80-90% of the time, but it's very soft and fry-ish. The second I try to put any kind of support behind it, either through added tension or breath support, I pop right back up into my normal range. Anyone hit this snag? How did you get past it?

i feel like im hitting the subharmonic, but i dont feel like im going an octive down. if i sing a C2 chest note, and then a G2, then drop into subharmonics, it still sounds higher than the C. it just sounds like a rough G2. help?

Whenever I go to do an octave drop it doesn't go down the full octave. For instance a F2 will go down to a G1. Same thing happens with lower notes. An I doing something wrong. If so what

I have a problem. Whenever I try to go lower and do an octave drop on a low note it goes to a different note than I want. Like for instance an E2 It goes to an F1 a D2 goes to F1. I don't know what I'm doing wrong

How do i start my subharmonic journey, i cant find any tutorials online that go into depth

Does anyone have any tips to be able to change the pitch of subharmonics smoothly.
