Violin Sonata No. 11 in E♭ major (K. 26)
ヴォルフガング・アマデウス・モーツァルト作
Mozart’s Violin Sonata No. 11 in E♭ major (K. 26) dates from 1766, when the ten-year-old composer was in The Hague during the family’s European Grand Tour. Though essentially a keyboard sonata with an optional violin part, it offers a vivid snapshot of Mozart’s early assimilation of fashionable galant style—and of how quickly he could turn travel, patronage, and performance into publishable music.
Mozart’s Life at the Time
In 1766 Wolfgang Amadeus Mozart (1756–1791) was ten years old and nearing the end of the long European “Grand Tour” undertaken with his family (1763–1766). The Hague, where K. 26 was composed, was one of the tour’s most significant Dutch stops; the city offered both courtly visibility and a market for printed music, and the Mozarts’ itinerary in the Low Countries coincided with a push to consolidate the child prodigy’s reputation through compositions suitable for domestic music-making.1

K. 26 belongs to a The Hague group of six “sonatas for keyboard with violin accompaniment” (K. 26–31). In other words, the balance of roles is historically the reverse of what modern concert culture sometimes assumes: these pieces were conceived primarily as keyboard works—brilliant, singable, and immediately legible—into which a violin could be added for color, reinforcement, and dialogue.12
Composition and Manuscript
The Sonata in E♭ major, K. 26 was written in The Hague in early 1766, and it stands at the head of the K. 26–31 set.1 Modern scholarly editions treat these works under the rubric “Sonatas and Variations for Keyboard & Violin,” reflecting their eighteenth-century identity as keyboard music that can accommodate a violin partner rather than requiring one.3 The score is widely accessible today through major critical and practical editions, and it appears in the Neue Mozart-Ausgabe (New Mozart Edition) volume devoted to these early keyboard-and-violin sonatas.4
If K. 26 is not “famous,” that is partly because it is not trying to be a late-classical chamber monument; it is juvenilia designed for the salons and music rooms that the Mozarts encountered on tour. Heard on its own terms, however, it is a valuable document of how Mozart learned to write for real players, real rooms, and real patrons—quickly, clearly, and with charm.
Musical Character
K. 26 is cast in three concise movements (a layout typical of many mid-century keyboard sonatas), with the keyboard carrying the principal thematic and harmonic argument and the violin generally functioning as accompaniment or light partner rather than a fully independent protagonist.12
What makes the sonata worth attention is precisely this early craft: Mozart’s instinct for balanced phrases, his feel for conversational cadences, and his ability to generate contrast without heavy contrapuntal machinery. E♭ major—often associated in his later music with warmth and a kind of ceremonial ease—already proves a congenial “public” key for him here, supporting extrovert opening gestures and graceful lyricism in the slower span. For performers and listeners, K. 26 also clarifies a broader historical point: in the 1760s, “violin sonata” could still mean a keyboard sonata first, with violin added—a genre convention Mozart would later outgrow as he moved toward genuinely two-part chamber dialogue in his mature violin-and-piano sonatas.2
