Long-Lost Mozart Composition Discovered in German Library

The 12-minute piece, written when Mozart was a teenager, has been performed for the first time in centuries.

The composition, titled 'Serenade in C' or 'Ganz kleine Nachtmusik,' was found in the Leipzig Municipal Libraries.
Researchers believe Mozart wrote the piece in the mid- to late-1760s when he was between 10 and 13 years old.
The manuscript is a copy made around 1780, attributed to 'Wolfgang Mozart,' but not in his handwriting.
The piece consists of seven miniature movements for a string trio and lasts about 12 minutes.
The composition was performed at the Leipzig Opera and outside the opera house for eager crowds.
