Mozart’s Fugue in D for Piano (K. Anh.H 13,01) is a short, cautiously attributed keyboard fugue associated with Bologna in 1770, when the composer was 14. Surviving references point to it as a contrapuntal study—an echo of the rigorous training Mozart pursued in the orbit of Padre Giovanni Battista Martini during his Italian journeys.[1][2]

Background and Context

In 1770, the 14-year-old Wolfgang Amadeus Mozart (1756–1791) spent significant time in Bologna during his first Italian tour, absorbing the city’s learned musical culture and seeking recognition among its leading musicians.[3] The piece is linked in reference sources to this Bologna milieu and is plausibly connected with Mozart’s contrapuntal work in and around Padre Giovanni Battista Martini (1706–1784), the renowned theorist with whom Mozart studied during the Italian sojourn.[3][4]

Musical Character

Notated as a fugue in D major for solo keyboard, the work is best understood as a compact exercise in learned style: a single subject stated plainly and then answered in imitation, with the texture tightening into a more continuous web of entries rather than aiming at virtuoso display.[2] Its focus is on clean voice-leading and functional harmonic motion (the kind of “on-the-page” discipline demanded by strict counterpoint), offering a glimpse of the teenage Mozart practicing procedures that would later resurface, far transformed, in his mature contrapuntal finales and church music.[3]
