Romance in A♭ major (K. Anh.C 27.04)
ヴォルフガング・アマデウス・モーツァルト作
The Romance in A♭ major (K. Anh.C 27.04) is a short, simply written piano piece transmitted only in early prints and attributed to Mozart with little supporting documentation. Its authorship remains doubtful, and neither a secure date nor a place of origin is known.
What Is Known
The work survives as a single-movement keyboard Romance in A♭ major, preserved not through an autograph but through later transmission; the Salzburg Mozarteum’s Köchel Verzeichnis records it among doubtful works and points to early printed editions, including a Vienna print by Tranquillo Mollo (1802) and other early reprints.[1] The Neue Mozart-Ausgabe (NMA) likewise treats the piece as problematic: its editors describe the “authenticity … as a whole” as highly dubious, while allowing (cautiously) that part of it could reflect a posthumous arrangement of otherwise lost Mozart material.[2]

Musical Content
As transmitted, the Romance is a modest, salon-like keyboard essay: a singing right-hand line supported by broken-chord accompaniment, with phrasing and cadence patterns that prioritize easy lyricism over contrapuntal or virtuoso display.[3] The NMA editors note “glaring weaknesses,” especially later in the piece—features that contribute to the doubtful attribution.[2] In performance, it is best approached as an attractive period Romance in A♭ rather than as secure evidence of Mozart’s pianistic development.
