How much does teeth affect in singing?

[RockSinger31]

Hello

I try to experiment with my voice by recording myself and hearing back. I try  open mouth so both my front and bottom teeth shows and the tone gets bigger and it sounds better. When i try to hide my bottom teeth the sound gets muffled and bad. Why is that? Does teeth affect tone?

Not the teeth itself, but the lips: when you cover your teeth, the lips are rounder and make the mouth opening smaller, resulting in a darker color, when you spread your lips, show your teeth, mouth opening becomes bigger, resulting in a brighter color.

You can test these extremes going from a OO vowel to AH for example.

Bring it old friend...

The teeth do influence the vocal sound. The teeth are reflective and add reflective frequencies to the sound color chemistry. 
 

Singers can hear the change in frequency (color) as you move your mouth in a more horizontal position and bring the molars closer together.

The end result is, the voice has more “bite” in the sound color, But it is subtle. It isn’t a big influencer. Great for belting and rock genres. 

I have even felt my teeth vibrate a couple times when I was really playing with it, although this was a rare occurrence.

hope this helps.

haha ok Rob I can agree that the teeth has some influence on acoustics (irrespective of feeling vibrations on them or not), however they are not capable of *doing much* they are a fixed element and whatever role they will play is just an outcome of the gesture made.

A *bite* for example is the jaw moving, possibly lips.

It is possible to hear the sound color of the molars in your singing, if the embouchure is horizontal = oral cavity is more closed. Subtly.

I mean should you show your bottom teeth or should you hide them on high notes?
