BEFORE YOU START TRYING TO BELT!!!!!
listen to a LOT of the classic belters, patti lupone etc. i'm not talking pop belters like idina, sherie (though i love her voice!!) - because that's a skill that can only come with real vocal maturity. listen to the classic belting technique, not just the song that's being sung. it really does help.
BUT DON'T TRY TO BELT TOO HIGH TOO FAST......it will only hurt you. i'd say stick below B until that gets to be second nature for you.
