I have been practicing my vocals for a while now and I need some help with low growls/gutturals just sounds so airy no growl or anything sometimes I can do it but when it happens it just hurts and makes my throat dry. Then for vocal Fry/screams it just hurts sometimes now with my research I heard that it just isn't good for it to hurt so please let me know if I'm doing something wrong and how I can fix it thank you.
