Forgotten Mozart melody found in French library

A forgotten melody, sketched in black ink in a swift, but sure hand, has been verified as the work of Mozart, the apparent underpinnings for a Mass he never composed.

The previously undocumented music fragment, a single manuscript page, long hidden in a provincial French library, gives an insight into Mozart’s evolving composition style and provides a clue about the role religion may have played for the composer as his life neared its turbulent end, an expert says.
