How does the drama in the quartet from rigoletto work differently from an ensemble scene in a spoken play?

Four characters are in the midst of a very ambiguous and dramatic situation, but all of them sing their own respective text and music lines, which intertwine and create beautiful harmonies. The Duke and Maddalena interact, but Gilda and Rigoletto sing for themselves. The drama is frozen in a single moment. On the other hand, in a spoken play, the drama moves forward in such scenes. It isn't restrained by music.

Yes and no because if you know the vocabulary used you will understand it and go faster but you might not need it
