Trumpet Concerto (lost), K. 47c
av Wolfgang Amadeus Mozart
Mozart’s Trumpet Concerto (K. 47c) is a putative, now-lost work associated with Vienna in 1768, when the composer was 12. It is chiefly notable as a doubtful item in the catalogue: no score or parts are known to survive, and its very existence is debated.
What Is Known
The Trumpet Concerto (K. 47c) is listed as a concerto “for trumpet and orchestra,” but its transmission is entirely lost; neither autograph nor copy is known today.[1] The most specific historical context attaches the piece to the Viennese celebrations at the Waisenhauskirche (orphanage church) on the Rennweg in December 1768, for which Leopold Mozart reported that Wolfgang had prepared church music and “a trumpet concerto for a boy.”[2]

At the same time, the work’s authenticity is not secure: the concerto is absent from Leopold’s own thematic list of his son’s compositions (as reported in the secondary literature), and modern discussion often treats K. 47c as doubtful—or even as a work that may never have existed in performable form.[2] In other words, K. 47c sits uneasily between “lost” and “possibly spurious.”
Musical Content
No music survives, and no incipit, movement plan, key, or instrumentation beyond “trumpet and orchestra” can be described with confidence.[1]
