THE MODERN VOCALIST

I guess you would have to define "belt" in the first place.

I use CVT-terminology. And they now use the term "Edge" which was formerly called "Belting". (They changed it because belting has to many different meanings).

Here is a quote from CVI about Edge/Belting:

"Edge is the other full metallic mode. There is a great amount of metal or edge on the notes. The character of Edge is light, aggressive, sharp, and screaming, like when you imitate a diving airplane. Edge can be found by twanging the epiglottic funnel (e.g. sounding like a duck).

Edge is used in popular music in some styles, and mostly in the high part of the voice when the volume needs to be very loud and with a great amount of metal on the notes, such as in heavy and gospel music. Edge is used in classical music when men sing very loudly (ff) often in the high part of the voice, such as the high c of a tenor. Women do not use Edge in classical music. Edge is used in everyday life when you scream.

Both men and women can use Edge in all parts of the voice. Only twanged vowels can be used, as the twanged epiglottic funnel is a condition of Edge. This means that in the high part of the voice you can only use I (as in sit), A (as in and), EH (as in stay), and OE (as in herb). The sound colour can only be altered a little. In the high part of the voice you must not alter the light and sharp sound colour. The volume in Edge stays mostly loud. The higher the notes, the more distinct the screaming character becomes. "

Hello Vocaltutor,
This is Lucy.As I know In any choir, there are four voice parts: soprano, alto, tenor, and bass. each one has a very different personality.  Each voice part sings in a different range and Sometimes these four are divided into first and second within each part. if you find any other explanation please do inform me.

Wish you guys could've witnessed TMV member Lisa Popeil at the Voice Conference a couple of weeks ago, demonstrating five different belts.  The x-rays of her vocal tract and the sound spectra were just incredible!

So, for that matter, is Lisa!   

Pete that is exactly what I just posted before I read your post. I saw Lisa's belt demonstration at the 2008 TVS symposium and it was really neat to hear different belts.
