Amazing, I've been working on subharmonics myself. I hope I get that good one day.

😮. Delightfully dark D1. Subharmonics or not that was very well done. 👏 Since I can't recognize pitch it read music well or really at all, I am curious to know what are the other notes you sing in the clip? Regardless, stay safe and stay awesome 🙃✌️

Wow, how is that even possible?

Kudos to the many, many hours of practice behind this! To me it sounds a bit forced & breathless at the very end but that may be due to my crappy earphones, not the singer 🤓

A1 sub sounds like chest.
