Does size of mouth affect singing?

Your mouth size definitely affects your singing, most significantly in terms of vocal range. The general rule is that those with smaller mouths have smaller vocal cords, resulting in a higher voice. Those with larger mouths and correspondingly larger heads may have bigger more powerful voices.

Why do great singers have big mouths?

The mouth can be shaped to make certain frequencies stand out. For example to amplify low frequencies you would need a larger volume to make the resonance work - this is due to the physics of sound waves. So the larger mouth space you have, the easier you would find it to make low frequencies stand out.

Does jaw shape affect singing?

If there is tension in the jaw, there could also be some tension in your voice too - It all correlates. When the jaw is tense this tension is transferred to the tongue muscles, the hyoid bone, your resonators and to the larynx (your voice box) which affects the quality of your singing.

Do teeth shape affect singing?

Many singers wear orthodontic braces and are still able to carry a tune and belt out the high notes. Braces do not affect your vocal cords. They simply correct issues with your teeth, giving you a beautiful smile. You'll need that smile to pose for pictures with your fans after every performance.
