Last Friday, the harpsichordist Florian Birsak performed in the Dancing Master’s Hall of the Mozart Residence in Salzburg, for the first time in something like two centuries, a small, 84-measure, Allegro Molto for keyboard believed to have been written by the eleven-year-old prodigy Wolfgang Amadeus Mozart circa 1767.
The composition was found last year in a 160-page collection of musical pieces discovered in the attic of a private home in the Tyrol. The manuscript was apparently written by a John Reiserer, born 1765 in Rattenburg, while a student at the UniversitÃ¤tsgymnasium in Salzburg, which he attended between 1778 and 1780.
Musicologists agree that the Allegro is a composition of Wolfgang Amadeus Mozart unrecorded in the KÃ¶chel directory of his compositions.
