Vocal music is not my major at college. I've been learning it as a hobby for more than ten years. My private teacher holds a recital of her students every September. I'll sing two arias from Italian opera: 'Son vergin vezzosa' from "I Puritani" and 'Oh! quante volte, oh! quante' from "I Capuleti ed i Montecchi". The latter one is Giulietta(=Juliet)'s aria.
The following two YouTube are Anna Netrebko's 'Son vergin vezzosa' and Sumi Jo's 'Oh! quante volte, oh! quante'. Sumi Jo is my favorite opera singer. I love her beautiful and transparent voice.
