Joan Sutherland as the Queen of the Night - Mozart: Die Zauberflöte
Covent Garden Orchestra & Chorus
Otto Klemperer
CDs have pitched Joan Sutherland's performances of the Queen of the Night's aria at B-flat & C-sharp (original keys B-flat & D), but a biography of Sutherland and Bonynge mentions that Bonynge transposed the arias into A and C minor.
I transposed the recordings down a half step -- and behold! it sounds a lot more like Joan Sutherland! I'm guessing that this is the original pitch. Enjoy the A major version.
