Today I went to see a opera group where the little girls were shaking their jaws. The louder the teacher asked them to sing, the more shaking of their jaws.

The teacher was asking them to make more vibrato and more rounded sound. The girls remind me of Charlotte Church or Jackie Evancho. They sound very very similar.

I sang for the teacher. And my voice has a lighter timbre naturally, even more than those little girls!! the teacher said to me that they have a more rounded sound.

this is another question, I don’t know what is a “rounded” sound exactly and why I don’t sound like that. Here is my singing:

Here is the singing of the little girl:

This is 2 years ago. Today the jaw shaking was more evident.

WHY??
It’s difficult to my voice to imitate the “rounded” sound that most of the opera singers have. I’m 19 years old by the way, and I am very impressed that the girls have a more mature timbre than mine. If I try to imitate that sound, I get very tired, and is more difficult to sing.
