"Mondschein Sonata"? WTF Apple? Not only is that factually wrong, but… that's not even German - neither as a whole, nor the "Sonata" nor the space (Deppenleerzeichen). Maybe Apple should ask someone else than Siri or a marketing intern to write texts with factual claims outside of their fields. The actual popular German sobriquet for that Sonata is "Mondscheinsonate". As for "Sonata", that's part of the (Italian) title of its first published edition: "Sonata quasi una Fantasia".
