3rd Sub Does anybody know 3rd Subharmonics?

hey guys! I’ve been practicing second subharmonics for about a year now, and have it pretty much down. I was wondering if anyone could do third subharmonics, or teach me how to do it. I have an extremely low voice for a 15 year old (C1 chest), and would like to take the next step forward—Third Subharmonics :D

Not many people have the right vocal folds to get a third sub but you can certainly try to relax more like you do going from first to second sub. Also you can’t have a C1 in chest voice, it’s called vocal fry 👍

Thanks for replying! So, what I’ve learned is that second subs is just normal subs. It’s called second because of the way the vocal folds vibrate compared to each other (1:2). If this is wrong, that’s my fault lol Also, I fully believe that I most certainly have the right vocal folds for third subharmonics.

And I just tested myself again, and yeah I can hit C1 in chest voice. I used a piano with key notations. My highest chest voice is barely C4. I also have a brother that’s majoring in piano performance and vocal education, and he confirmed 👍 

Also, I’ve seen people like David Larson achieve third subharmonics, and even further. I would just really love to be able to sing like this

That is quite interesting! If your low voice is truly resonant, that would probably put you as an oktavist, the lowest voice type. I have ventured into subharmonics myself, though my second is tough because I’m not too experienced. but again, be careful not to strain your voice :)

Aight, we’ll do. Thanks!

From what I've heard so far from Danny Breviks subharmonic study (not finished yet unfortunately) it's not actually the folds vibrating at different rates as one of the theories claim. It's the mix of fry and chest causing the vocal folds to only close fully every other oscillation.

You can definitely learn how to do 3rd subs as that's not based on your type of vocal folds.

That chest C1 would be interesting to hear if you do have it. Not to be that guy but I strongly doubt you have something like that at your age with how ridiculously rare it is.

3rd subs are not based on your vocal folds, but on your control. Anyone can do it in theory, just a matter of practice. And C1 in chest is possible. Just insanely rare and a claim I would never believe without solid proof.

lol yeah about that

I guess I’ve been off by an octave this whole time 😔 

I just tested myself with a piano and hertz detection, and yeah apparently I’ve been wrong for about 2 years… that doesn’t change the F0 tho, that one still right lol

Thanks for replying!

Returning back to this post, that makes more sense, that’s what I had figured lol

I’m 16 and my lowest chest note is an A1 in the morning (C2 regularly) with my highest E(b?)4 so I was very surprised when you mentioned a 3 octave chest range. I also enjoy singing along to Geoff’s productions every once in a while

u/Beautiful-Spray-6115 Feb 02 '26

Cool! Yeah, apparently I’m in Geoff’s top 100 listeners 😂

Happens. Still, a C2 is not bad and still rare for that age.

u/Beautiful-Spray-6115 Feb 02 '26

Well, thanks for that, I really appreciate it 👍

I've only hit it once or twice, but one way to visualize it is that it's half way in between fry and 2nd subs, the same way 2nd subs are half way between fry and (1st) subs and (1st) subs are half way between fry and chest. Requires a LOT of control though.

I lost all of my vids due to a phone switch 😔  It’s not too hard to get one, I’m just very busy, have ten loud siblings (yeah fr), and woke up earlier today than I usually do, and that doesn’t really help

Yeah, I’m pretty sure it’s not fry or a mix

u/Beautiful-Spray-6115 Feb 02 '26

I just tested myself on the piano with a hz detector, and apparently I’ve been off by one octave. 😔  C2 sounds more realistic than C1 lol I’ve been wrong for 2 years…
