One detail in a 248-year-old notebook changed everything for music historians

A forgotten Mozart manuscript, containing seven short pieces for flute and harp, has been discovered in a 248-year-old notebook. Curators recognized Mozart's distinctive handwriting, leading musicologists to confirm the find. These collaborative works, created in 1778 with his student Marie-Louise-Philippine de Bonnières de Guînes, were performed publicly for the first time this month, offering a rare glimpse into the composer's teaching methods.
