Researchers discovered a 44-page [1] manuscript containing seven [1] previously unknown works by Wolfgang Amadeus Mozart at the French National Library in Paris.

The find is considered one of the most significant musical discoveries of recent decades. It adds new compositions to the established oeuvre of one of history's most influential composers, offering fresh insight into his creative process and instrumental preferences.

François-Pierre Goy, a conservator in the music department of the French National Library, identified the manuscript. The documents contain seven pieces written specifically for the harp and flute [1], as well as various compositional exercises [3].

Experts differ on the specific origins of the pieces. According to the Süddeutsche Zeitung, Mozart wrote the compositions for a harpist he admired [5]. However, BR-Klassik said the pieces likely date from Mozart's tenure as a teacher at the court of the Count de Guîne [6].

The discovery has prompted immediate preparations for a public debut. The pieces are scheduled to be performed for the first time this Sunday [1, 2].

This discovery highlights the ongoing role of physical archives in musicology. While much of the world's musical heritage is digitized, the presence of a 44-page [1] manuscript in a national library demonstrates that major works by canonical composers can still remain hidden for centuries.

The emergence of these works provides a rare opportunity to study Mozart's transition and experimentation with specific instrument pairings. Because the manuscript includes compositional exercises alongside finished pieces, it offers a window into the technical scaffolding Mozart used to build his compositions, potentially altering the academic understanding of his pedagogical methods and his relationship with the French aristocracy.
