caruso

I hope you are refering to a note beneath the hi"C". Mr Pavarotti always used the passagio. The two main tenors who did not do not use it are Carlo Bergonzi & Juan Diego Florenz. By the way, it is the correct way to sing. Pavarotti both chested and covered F#. In fact, he covered at least as low as E, and chested at least up to G.
