Mozart’s “Marcia” (K. 626b/49) is a lost march transmitted only as a catalogue entry, with no surviving score and no secure date, place, or key. It is therefore treated as a doubtful (possibly spurious) item within the supplementary layer of the Köchel listing.
What Is Known
The work titled “Marcia” appears in the Köchel catalogue as K. 626b/49, but is explicitly lost: no autograph, copy, or early print is currently known, and standard reference data such as key, scoring, date, and place of composition remain unreported in accessible summaries.[1] In the absence of a musical source, its provenance and authenticity cannot be verified, and it is best regarded as a doubtful attribution rather than a securely documented Mozart composition.[1]
Musical Content
Because no music survives, nothing reliable can be said about the piece’s thematic material, form, or instrumentation. The title Marcia merely indicates the genre of a march, without confirming whether it belonged to a theatrical, ceremonial, or domestic context.[1]
