The two new Mozart pieces were performed today in Salzburg by Austrian pianist Florian Birsak on Mozart’s own piano an a house in Salzburg where he once lived. According to the story on NewsDaily:
The concerto movement and a prelude were originally judged by their archivist, the International Mozarteum Foundation, to be anonymous works. Further analysis determined they had been composed by Mozart when he was 7- or 8-years-old.
Both pieces were transcribed in the writing of Mozart’s father Leopold but the analysis showed he must have done so from what his prodigy child was playing on a piano, the foundation’s Mozart researcher Ulrich Leisinger told a news conference.
He said the young Mozart almost certainly asked his father to put the pieces to paper because he could not yet do musical notation, and later made his own corrections.
“This was a young composer running riot to show what he was capable of. The piece does contain real technical mistakes and clumsy moments that an old hand like Leopold Mozart would never have made,” Leisinger said.
“Neither the compositional style nor hasty correction-ridden hand-writing are consistent with Leopold’s authorship.
