US mezzo soprano Joyce DiDonato won the singer award.
She was honoured for her role as Elena in Rossini's La Donna del Lago at the Royal Opera House and also her performance at the Last Night of the Proms. It is the second time she has won the award.

He has joined an illustrious group of RPS gold medallists including Barenboim, Sir Simon Rattle and Placido Domingo.
In a statement, the RPS said: "There are no pretensions about John Tom. For him, celebrity status is irrelevant - the crucial thing is singing; and it is the desire to sing and communicate, and the obsession to get it right every time, that drive him."
Welsh National Opera won the opera and music theatre award for productions including Lulu, Lohengrin and Paul Bunyan.
London's Southbank Centre picked up the festivals and series award for its year-long classical music festival, The Rest is Noise.
A special programme devoted to the RPS Music Awards will be broadcast on BBC Radio 3 on Sunday at 2200 BST.
Outgoing Proms director and controller of BBC Radio 3 Roger Wright said: "The range of the year's awards is another sign of the high quality in live music-making and new work.
"We are thrilled to have broadcast so much of the award-winning music and performers - and, in particular, to have been responsible through the BBC Proms for the remarkable Ring cycle conducted by Daniel Barenboim."
