my friend used to have a tape that had vocal stretches on it and when oyu do those everyday its supposed to make you sing better but she lost it so is there anything online that does that or download ect...?

I am a voice teacher and I'm telling you that you just need to do your scales. DO. Re. Me's and it will stretch your voice. Also be sure to breath correctly.
