        "content": "Billy Joel\u2019s song \u201cThis Night,\u201d from his 1983 album *An Innocent Man*, is based around the second movement (Adagio cantabile) of Beethoven\u2019s *Piano Sonata No. 8 in C minor* (often called the *Path\u00e9tique Sonata*) ([classicfm.com](https://www.classicfm.com/composers/beethoven/billy-joel-beethoven-pathetique/?utm_source=openai)).\n\nHere\u2019s a breakdown:\n\n- The **chorus melody** of \u201cThis Night\u201d lifts directly from Beethoven\u2019s *Adagio cantabile* (the second movement of *Sonata No. 8*) ([classicfm.com](https://www.classicfm.com/composers/beethoven/billy-joel-beethoven-pathetique/?utm_source=openai)).\n- Because of this, **Ludwig van Beethoven** is credited as a co-writer on the single sleeve \u2014 listed alongside Billy Joel. ([en.wikipedia.org](https://en.wikipedia.org/wiki/This_Night_%28Billy_Joel_song%29?utm_source=openai)).\n\nSo the classical piece is Beethoven\u2019s *Piano Sonata No. 8* (\u201cPath\u00e9tique\u201d), specifically its slow, lyrical second movement."
