The priceless, original score to Mozart's celebrated Piano Sonata No. 11 in A Major, including fragments of the famed 'Rondo alla Turca' final movement, has been unearthed in the archives of the Budapest National Szechenyi Library.
“When I first laid eyes upon the manuscript, the handwriting already looked suspiciously "Mozartish" … then I started reading the notes and realised it was the famous A Major Sonata,’ Musicologist Balazs Mikusi, Head of the Library's music collection has told the Agence France Presse.
