Picture an ocean wave.

A big white cap.

Now zoom in real close on the top of your wave and you'll notice a mist hovering right above it, traveling with the wave.

If you were trying to capture the perfect image of this wave, you could Photoshop that mist out of the picture.

It's just visual noise.

Every sound you've ever heard in your life is a wave.

Sound waves have that mist above them too.

We call them overtones.

Picking a string on your acoustic guitar doesn't produce a perfect tone of the note you want to hear.

Your guitar string mainly produces that tone, but you get some overtones in the deal as well.

Playing a bunch of different tones together in a chord gives you even more overtones, all splashing into each other.

This is especially noticeable on acoustic guitars because of the way they're built to project sound by allowing it to resonate in the music.

The body of the instrument.

The human voice functions in a very similar manner.

Your chest, mouth and nasal cavity are three of the seven resonators your body uses to create vocal sounds.

So if an acoustic guitar generates a lot of overtones with one resonating chamber and the human body has seven.

The sounds you're hearing are all being produced by one person's body.

There is no other instrument or physical device helping them do it.

It's called throat singing and it's been happening in Mongolia for a very long time.

The singer creates a tone in their throat and exaggerates the overtones by manipulating the muscles in their throat and mouth.

It's like a magic trick except knowing how it's done doesn't make it any less amazing.

You may be wondering why a show about country music is opening with Mongolia and throat singing.
