Cello Concerto in F major (lost), K. 206a
di Wolfgang Amadeus Mozart
Mozart’s Cello Concerto in F major (K. 206a) is a reported but lost work, dated by the International Mozarteum Foundation’s Köchel catalogue to March 1775 and marked as of doubtful authenticity. If it existed as described, it would belong to the same youthful concerto world as Mozart’s violin concertos from his nineteenth year—music designed to flatter a virtuoso while keeping the orchestra in a bright, buoyant F-major frame.
What Is Known
The International Mozarteum Foundation’s online Köchel catalogue lists Concerto in F for violoncello and orchestra, K. 206a, as a lost work and assigns it doubtful authenticity; it is nonetheless treated there as a completed work, dated to Salzburg, March 1775, in F major.[1] No musical text is presently available: neither score nor parts are known to survive, and the entry provides no usable incipits or movement data for reconstruction.[1]

In terms of Mozart’s development, the date places K. 206a beside the concertante idiom of 1774–75, when he was writing confident public-facing works for soloist and orchestra (most famously the violin concertos of 1775). Even so, the catalogue’s “doubtful” tag means that any attempt to hear K. 206a as a missing link in Mozart’s concerto style must remain provisional.[1]
Musical Content
Because no notated music for K. 206a is currently known to survive, it is not possible to describe its themes, movement plan, orchestration, or cello writing in a way that is grounded in sources. The work remains, at present, a title and catalogue record rather than a performable concerto.[1]
