Serenade for 2 Violins, Cello, and Organ (lost), K. 41g (doubtful)
de Wolfgang Amadeus Mozart

Mozart’s Serenade for two violins, cello, and organ (K. 41g) is a lost Salzburg work of 1767, traditionally linked to the 11-year-old composer but regarded as doubtful or possibly spurious. What survives is essentially a catalog trace: a title-like description and an indication of forces, with no music to examine.
Mozart's Life at the Time
In 1767, Wolfgang Amadeus Mozart (1756–1791) was 11 and based in Salzburg, writing a steady stream of short occasional pieces alongside larger sacred and instrumental works. K. 41g belongs to a cluster of similarly elusive Salzburg items from the same year—marches, minuets, and fugues now also lost—suggesting practical music-making rather than a work aimed at publication or wide circulation [1].

Musical Character
No score or parts for K. 41g are known to survive, so its key, movements, and formal design cannot be described with confidence [1]. The scoring—two violins, cello, and organ—points toward a small serenade-like Nachtmusik with continuo, a format that in Salzburg could serve either domestic entertainment or semi-liturgical contexts (the organ reinforcing harmony while the strings carry the melodic argument) [1].
The work is often treated as of doubtful authenticity in modern Mozart reference culture, and should be approached as a lost item whose attribution remains uncertain [2].
