Symphony No. 26 in E♭ major, K. 184 (1773)
par Wolfgang Amadeus Mozart
Mozart’s Symphony No. 26 in E♭ major, K. 184 was completed in Salzburg on 30 March 1773, when the composer was 17. Compact, brilliant, and theatrically alert, it shows Mozart refining the three-movement “overture” symphony into something more searching—especially in its unexpectedly dark slow movement.
Background and Context
In 1773, Wolfgang Amadeus Mozart (1756–1791) was back in Salzburg after his third Italian journey, once again embedded in the court musical life of Archbishop Hieronymus Colloredo. The symphonies of this period often served practical needs—concert use at court, festive occasions, or as adaptable opening pieces—and Mozart’s Salzburg works frequently move with the directness and flair of an operatic curtain-raiser. Symphony No. 26 in E♭ major, K. 184 belongs to that world: it is concise, high-contrast, and engineered to make an immediate impact.[3]

Yet K. 184 also hints at Mozart’s next step. Compared with many earlier Salzburg symphonies (often content with genial surface brilliance), this one repeatedly tightens the musical argument—sharp gestures in the outer movements, and a slow movement whose tonal choice (C minor) adds a streak of seriousness not “required” by its social function. In miniature, it previews Mozart’s growing ability to fold drama and lyric introspection into the symphonic frame.
Composition and Premiere
The autograph sources preserve unusually concrete evidence for dating. A full-score manuscript at The Morgan Library & Museum is titled as Symphony no. 26 in E♭ major, K. 184 (161a) and dated 30 March 1773, with an Italian inscription naming “Cavaliere Amadeo Mozart.”[1] That same record notes a fascinating patchwork of hands: the opening pages of the first movement are in Leopold Mozart’s hand, while the latter portion of that movement is by a copyist, and the second and third movements are in Wolfgang’s own hand.[1] Whatever the exact copying circumstances, the documentation anchors the work firmly in Salzburg in spring 1773.
Like many Salzburg symphonies, K. 184 has no securely documented first performance. Its three-movement plan and brisk profile, however, made it adaptable—one reason such works could circulate in multiple contexts, from court concerts to theatrical use. Modern scholarship has also discussed whether some 1773 symphonies have more complicated dating than the traditional March attributions, so the “30 March 1773” date is best understood as a strong source-based reference point rather than an immovable historical certainty.[1][4]
Instrumentation
Although K. 184 is often characterized as an E♭-major symphony “for oboes, horns, and strings,” its surviving sources and modern editions reflect a broader Salzburg palette. The work is scored for:[3]
- Woodwinds: 2 flutes, 2 oboes, 2 bassoons
- Brass: 2 horns, 2 trumpets
- Strings: violins I & II, viola, cello, double bass
This is, on paper, a festive E♭-major orchestra—trumpets and the bright edge of winds suggesting ceremonial brilliance. In practice, performances may reflect period flexibility (doubling, availability of players, and local custom), but the listed scoring underlines Mozart’s intention to think in clearly colored orchestral layers rather than in strings alone.[3][2]
Form and Musical Character
K. 184 follows the familiar fast–slow–fast plan, a “three-movement symphony” closely related to the Italian sinfonia and to operatic overture practice. But Mozart’s handling of contrast—especially tonal and affective contrast—gives the work more personality than its modest scale might suggest.[3]
I. Molto presto (E♭ major)
The opening is all forward motion: a clipped, bright attack that feels designed to seize attention immediately. The movement’s energy is not simply “fast”; it is urgent, with quick changes of texture—full orchestral assertions giving way to leaner string writing and back again. One can hear Mozart balancing two imperatives: the overture-like need for instant impact, and the symphonic need for coherent argument. Even within a compact span, he sharpens motifs so they can be thrown into different lights (tutti versus lighter scoring), keeping the musical surface lively without losing structural focus.

II. Andante (C minor)
The slow movement’s key is the first real signal that this symphony deserves closer listening. C minor (the relative minor of E♭ major) brings a shaded, inward tone, and Mozart treats it with a seriousness that cuts against any assumption that K. 184 is merely “functional.” The movement’s restrained pace invites expressive detail—sighing figures, tense harmonies, and a sense of gravitas that seems to glance ahead to Mozart’s later minor-key eloquence. In the context of a three-movement Salzburg symphony, it is precisely this turn toward the darker and more intimate that lingers in the memory.
III. Allegro (E♭ major)
The finale restores brightness, but it is not simple cheerfulness; rather, it is theatrical release. Its quick meter and bustling rhythms evoke stage-business and crowd movement, with phrases that snap into place and propel the music forward. The effect is of Mozart “closing the curtain” briskly: the symphony ends with confident motion rather than with weighty summation. That sense of an ending designed to clear the air—after the minor-key Andante—is part of the work’s charm and structural logic.
Reception and Legacy
K. 184 is not among the handful of Mozart symphonies that dominate concert life, partly because it inhabits an in-between category: too mature to be treated as a mere juvenile curiosity, yet far smaller in scale than the great late triptych of 1788. Still, it has remained accessible to performers and audiences because it communicates quickly and rewards stylistic finesse—ideal for programs exploring Mozart’s Salzburg years or the Italianate symphonic tradition.
Its legacy, in other words, is less about fame than about perspective. Heard alongside the more overtly dramatic Symphony No. 25 in G minor, K. 183 (also 1773) or the later breakthrough of Symphony No. 29 in A major, K. 201 (1774), K. 184 clarifies a crucial point: Mozart’s symphonic evolution was not a sudden leap from “early” to “late,” but a steady sharpening of expressive contrast and orchestral thinking in works that could still function as elegant public openers.[1][3] For listeners, it offers a concentrated portrait of the 17-year-old Mozart as a professional court musician—already able to turn a practical genre into a compact drama.
