BACK AWAY FROM THE CHEST VOICE:
It's ok to belt in moderation..but you should never PRACTICE your chest voice belt. Sing in soprano, warm up in soprano, do EVERYTHING in soprano...you will never loose the chest part. In fact the more you sing and expand the soprano range the more your chest belt will come out healthfully and clearly. If you sing in your chest voice in those high ranges you break down the voice as a whole.
The best thing to do (I used to be a nothing-but chest belter) is to get a voice teacher and build up that soprano voice, and work to getting that belt sound in soprano, or getting a HEALTHY approach to a chest belt.
JMO...GOOD luck..it's a lot of work, but amazing the difference it makes!
and all that I could do because of you was talk of love...
