Do people really have two sets of vocal chords? Is it really possible to speak/sing with dual voices?

Question

if so, how is it learned? do buddhist monks really do this? can anybody learn it?

Answer 1

It's not that people have two sets of vocal chords, it's that some people can make full use of them. Some Tibetan monks can chant in different octaves at the same time the way that some people make more use of the capabilities of their brains than the rest of us normally do. See Holographic Paradigm.

Answer 2

No. Not unless they have some kind of serious anomaly. I've never heard of it.

The vocal folds (that's what we call it in the biz) are thick flaps of muscle that vibrate against each other. "Throat singing", as done by Tuvalu and Inuit groups (maybe others), is just a singing technique that uses the vocal folds in a different way.

As children are growing up, they make pretty much all the noises heard in every world language. You call it "babbling." I call it practice. As children hear the language/s around them, they narrow their focus to just the sounds of their language. They practice that and get good at speaking their native language.

Anybody could conceivably do throat singing. We're all capable of learning any language (as long as we learn it early enough or have a lot of motivation), so singing techniques could possibly be learned by anybody in the world. Practice enough, you get good, you sing two notes at once.

It's amazing, but not because of structural differences. Just practice and musical talent.

(Singing in tune is not innate and not everybody can do it. Just a disclaimer.)

Answer 3

Well,we don't have two sets of vocal folds ,but we have different tones & different ranges of frequencies that we can use which is considered to be individual features.for example the Opera singers do have "Soprano" level which most of us don't have
Monks for example have "basso" level which is frequencyis so low(64 Hz)
But by training we could be able to get all of the six ranges(Basso,Bariton,Tenor,Contralto,Mezosoprano and Soprano)
but these trainings should be at an early age(we can say better to be not should) .
Hope it helps.
