Seattle Opera presents its first-ever Gilbert & Sullivan in October 2025: The Pirates of Penzance, in a charming, traditional production that has already delighted many American opera audiences. Jonathan Dean explains the difference between opera and operetta, shares a bit of the music and humor of Pirates, and attempts to explain what The Pirates of Penzance is all about. Musical examples from Seattle Opera recordings of Rigoletto and Il trovatore, plus a recording of Pirates provided by the Atlanta Opera Film Studio (with Susanne Burgess as Mabel and Santiago Ballerini as Frederic, Chorus and Orchestra of Atlanta Opera conducted by Francesco Milioto) and another recorded in 1959 by EMI, featuring George Baker as the Major-General, James Milligan as the Pirate King, Owen Brannigan as the Police Sergeant, plus the Glyndebourne Festival Chorus and the Pro Arte Orchestra conducted by Sir Malcolm Sargent.
