Lost Mozart Music Found After 248 Years in Paris Library

A music curator stumbled upon a treasure that had been hiding in plain sight for nearly 250 years: original compositions by Wolfgang Amadeus Mozart that no one has ever heard performed.

Francois-Pierre Goy was sorting through a stack of anonymous manuscripts at France's National Library, trying to clear his desk before retirement, when he found something remarkable. The 44-page notebook contained exercises and musical pieces written by Mozart himself in 1778 when he was just 22 years old.

"I never imagined what I was about to find," Goy told reporters. He noticed the distinctive handwriting features that matched Mozart's style, including rounded treble clefs tilted slightly forward and bass clefs drawn backward from the French standard.

The notebook reveals a lesser-known side of Mozart: a young teacher working with an aristocratic French student named Marie-Louise-Philippine de Bonnieres de Guines. She was an excellent harpist and daughter of the Duke of Guines, a renowned flautist. Mozart gave her a dozen daily exercises and composed seven pieces for flute and harp during their lessons from May to July 1778.

The manuscript had been confiscated from the Duke's home during the French Revolution in 1794 and eventually ended up at the National Library. It sat unidentified in the collection for over two centuries.

Experts from the Austria-based Mozarteum Foundation authenticated the document in April. This Sunday, musicians will perform the pieces publicly for the very first time at a special concert at the library.

Why This Inspires

For harpists and flautists, this discovery is especially meaningful. These musicians have very limited classical repertoire available to them, so finding new Mozart pieces opens up exciting possibilities. The manuscript also fills in gaps about Mozart's final visit to Paris, a period of his life that historians know little about.

Mathias Auclair, director of the library's music department, emphasized how rare this is. Discoveries like this "for such a famous composer are almost unheard of," he said.

The find proves that treasures still wait to be discovered in libraries and archives around the world. Sometimes the most extraordinary things are sitting right in front of us, just waiting for someone to recognize them.
