A short but previously lost piece by Wolfgang Amadeus Mozart was recently performed just last week on January 27th, Mozart’s 265th birthday. The brief allegro can be heard below:
A bit more about the piece from the Mozarteum Foundation:
The present Allegro in D major for piano was hitherto known only from 20th-century sales and auction catalogues, where it had been described as a “sketch for a composition for orchestra or chamber ensemble”. On the basis of this vague information, musicologist Alfred Einstein assigned the piece the number App. 109g/16 in the third edition of the so-called Koechel catalogue, which finally became K. 626b/16 in the sixth edition. A music-loving engineer bought the autograph manuscript in an antiquarian bookstore in Paris in the late 1920s; his descendants kept it in the Netherlands for 90 years. When the manuscript was offered to the Salzburg Mozarteum Foundation it became immediately evident that it was not merely a sketch, but a complete work for piano in Mozart’s own handwriting, a piece unrelated to all known compositions. Finds of this kind have become extremely rare; the last comparable case was the rediscovery of the Allegro in F major for piano, K. 33B in 1937.
Although short, I think the work is ingenius. It’s quality work. And there are simply too many notes, that’s all. Just cut a few and it’ll be perfect.
