"Salgo gia" is the big aria from Nabucco.
Callas did it.
Guleghina did it.
A lot of people like Ghena Dimitrova.
I am trying to integrate the existence of this role into my history of singing. Our tradition says it is to be sung by a very heavy dramatic soprano. But what happens when it isn't? It's still convincing. The question I am still asking is: can we project this type of heavy technique back into the past? There was much discussion when tenors began to sing with a much heavier technique, but I don't recall a similar focus on sopranos. Does the presence of rage arias mean heavy singing? Is a puzzlement.
