Curators at the Bibliothèque nationale de France have rediscovered a notebook containing previously unpublished compositions by Wolfgang Amadeus Mozart [1].
The discovery adds new material to the catalog of one of history's most influential composers. Because the works remained hidden for centuries, their first public performance provides a rare glimpse into Mozart's creative process during a pivotal era of his development.
The manuscript was recovered during routine archival work at France's National Library in Paris [1]. The pieces were composed in 1778 [2], a period when Mozart was 22 years old [2].
To celebrate the recovery of the works, the library has scheduled a public performance for June 21, 2024 [1]. This event coincides with the Fête de la Musique, an annual celebration of music in France. The performance marks the first time these specific compositions will be heard by a public audience since they were written.
The notebook had been forgotten within the library's archives for centuries [1]. Curators said that the recovery happened as a result of standard archival procedures, highlighting the ongoing importance of physical manuscript preservation in the digital age.
While the compositions were written over two centuries ago, the timing of the performance allows the Fête de la Musique to serve as a global platform for the debut. The rediscovery underscores the possibility that other lost works by classical masters may still reside in uncatalogued sections of major European libraries [1].
“The pieces were composed in 1778 when Mozart was 22.”
The recovery of unpublished works from Mozart's early adulthood provides musicologists with primary data on his stylistic evolution in the late 18th century. By linking the debut to the Fête de la Musique, the Bibliothèque nationale de France is leveraging a high-profile cultural event to increase the visibility of archival research and the preservation of physical manuscripts.
