Clavier Concerto Movement (lost), K. 627
von Wolfgang Amadeus Mozart
Mozart’s Clavier concerto movement (K. 627) is a lost juvenilia item dated to 9 June 1763 in Salzburg, when the composer was seven years old [1]. Known only by catalogue report, it survives without score, parts, or even a key designation, and its attribution has been treated with caution in modern scholarship.
What Is Known
The Internationale Stiftung Mozarteum’s Köchel Verzeichnis records a lost “Concerto movement for clavier,” dated Salzburg, 9 June 1763, and classed as a completed work whose transmission is lost [1]. No musical text is presently available to consult—neither autograph, copy, nor orchestral material—so the movement cannot be checked for style, scoring, or even basic formal plan.

The date places the entry at a moment when Mozart, recently returned from the first phase of the great family tour (1762–63), was back in Salzburg and producing short pieces at a prodigious rate under Leopold Mozart’s close supervision. Because the work is known only from catalogue testimony and lacks surviving musical evidence, it is reasonable to regard K. 627 as a doubtful or at least unverified concerto-related item rather than a securely attributable early keyboard concerto movement.
Musical Content
No notes survive, and no incipit, instrumentation, or key is transmitted in the catalogue record; accordingly, K. 627’s musical content cannot be described beyond its identification as a single concerto movement “for clavier.” [1]
