Mozart manuscript discovered!

From Quest TV: One of the rarest finds in classical music history has just emerged from the archives of the Bibliothèque nationale de France: an unpublished Mozart manuscript, lying unidentified for over 230 years. Announced on June 19, 2026 and reported by Libération, the 44-page notebook was uncovered by BNF curator François-Pierre Goy, who recognised the characteristic marks of Mozart's handwriting while reviewing a batch of anonymous manuscripts.

Authenticated by the Mozarteum in Salzburg, the document contains twelve composition lessons Mozart gave in Paris in 1778 to Marie-Louise-Philippine de Bonnières de Guines, first known pupil in composition, alongside seven original pieces for flute and harp. Mozart himself famously complained to his father that his student had "no ideas," yet the pieces show a rich pedagogical dialogue between master and pupil. The world premiere of the works was performed on June 21, 2026 at the BNF during the Fête de la Musique, by Mathilde Calderini (flute) and Nicolas Tulliez (harp). The recording will be broadcast on France Musique on June 22 at 3pm. For flutists and harpists, who have limited repertoire available, the discovery of seven new Mozart pieces is, in the words of the BNF's music director, nothing short of "miraculous."
