Mozart's new piece in 432Hz

In 1778, while staying in Paris, the 22-year-old Mozart composed Seven Pieces for Flute and Harp for his first composition student, the noblewoman Marie-Louise-Philippine de Bonnières de Guines (daughter of the Duke of Guines). The Duke of Guines was an accomplished flautist, while his daughter was a virtuoso harpist. Later, during the French Revolution (1794), the Duke's possessions were confiscated and ended up in library collections; these materials resurfaced after 232 years. François-Pierre Goy, a librarian in the Music Department of the Bibliothèque nationale de France (BnF), stumbled upon this 44-page music manuscript while cataloging and investigating a large pile of "scores of unknown authorship" prior to his retirement. Goy noticed the handwriting and launched an investigation; following authentication by experts from the International Mozarteum Foundation in Salzburg, Austria, in April 2026, it was officially confirmed to be an authentic Mozart manuscript. On June 19, the library and Radio France jointly announced this "major discovery" to the world, and the world premiere of the work took place at the library on June 21. The performers were Radio France harpist Nicolas Tulliez and flautist Mathilde Calderini. The recording is from the Radio France program *Relax*. Since the tuning standard in Mozart's time was A4=432Hz—whereas modern orchestras use A4=440Hz—I used software to lower the pitch, restoring it to match the pitch used by the master himself. #音乐 #莫扎特 #432Hz #Retune432 #新曲子 #古典音乐 #hifi
