Mozart’s signature.

In Friday’s (9/20) CBS News, a report from Agence France Presse states, “A previously unknown piece of music likely composed by a teenage Wolfgang Amadeus Mozart was recently uncovered at a library in Germany. The piece, which dates to the mid- to late-1760s, consists of seven miniature movements for a string trio. It lasts around 12 minutes, researchers with the Leipzig Municipal Libraries said … Researchers discovered the work at the city’s music library while compiling the latest edition of the so-called Koechel catalog, the definitive archive of Mozart’s musical works. The piece is referred to as ‘Ganz kleine Nachtmusik’ in the new Koechel catalog … The Koechel catalog describes the piece as ‘preserved in a single source’ … The newly discovered manuscript, which consists of dark brown ink on medium-white handmade paper, was not penned by Mozart himself but is believed to be a copy made around 1780 … A list by Mozart’s father had alerted academics to the existence of ‘many other chamber music compositions’ by the young artist, which were all thought to have been lost until the emergence of the string trio.”
