What makes opera singers different?

Opera singer Joyce DiDonato explains what separates her trade from that of other classical vocalists.

Opera "shows humanity at its greatest", American mezzo-soprano Joyce DiDonato has said.

She explained to BBC Radio 4's Today programme that the art of an opera singer is to perform without amplification, often for hours at a time.

Ms DiDonato added that it was this skill, above all, that separates opera singers from other classical vocalists.

First broadcast on BBC Radio 4's Today programme on Thursday 12 June.
