Symphony No. 31 in D major, “Paris” (K. 297/300a)
볼프강 아마데우스 모차르트 작
Mozart’s Symphony No. 31 in D major (K. 297, often cited as K. 297/300a), composed in Paris in 1778 when he was 22, is his most deliberate encounter with the city’s public orchestral culture. Written for the Concert Spirituel and its taste for brilliance, massed forces, and theatrical surprise, the “Paris” Symphony turns cosmopolitan showmanship into unusually concentrated symphonic argument.
Background and Context
When Wolfgang Amadeus Mozart (1756–1791) arrived in Paris in March 1778, he did so as a freelance virtuoso-composer in search of a stable post—and in one of Europe’s most competitive musical capitals. Paris offered visibility (and money) through a public concert economy rather than court appointment, with institutions such as the Concert Spirituel providing a stage for new symphonies, concertos, and sacred works. The “Paris” Symphony emerged from this world: it is not merely a Salzburg symphony exported to France, but a work shaped by what Mozart heard, what he was paid for, and what he learned (sometimes painfully) in rehearsal.

Mozart’s Paris months were also personally volatile. The city brought new contacts (including patrons and publishers), but also professional frustrations, and—most devastatingly—the death of his mother, Anna Maria Mozart, in Paris on 3 July 1778. In the same letter with which he broke the news to Leopold Mozart, Mozart also tried to keep his father’s spirits from collapsing entirely by reporting, in unusually concrete detail, on the reception of his new symphony—an extraordinary juxtaposition that reminds us how tightly livelihood and artistry were bound for him in 1778 [4].
Two Parisian expectations, in particular, leave fingerprints on K. 297. First, sheer sound: Paris orchestras were praised (and sometimes feared) for their heft—more players, stronger winds, and an audience that treated orchestral writing as spectacle. Second, the audience’s appetite for instantly legible effects: big unisons, emphatic cadences, and surprises that could trigger applause even during a movement. Mozart did not sneer at this. He studied it and wrote toward it.
Composition and Premiere
The symphony was composed in Paris in 1778 for Joseph Legros (often spelled Le Gros), the director of the Concert Spirituel, who had commissioned Mozart and could supply the kind of orchestra Salzburg rarely did [1]. The usual headline date is the public performance at the Concert Spirituel on 18 June 1778, but sources also point to an earlier private hearing on 12 June 1778 at the home of Count Karl Heinrich Joseph von Sickingen (the Palatine ambassador), suggesting Mozart had at least two crucial “first tests”: one elite and controlled, one public and unpredictable [1].
Mozart’s own reporting makes the premiere season feel unusually vivid. In a long letter to Leopold dated 3 July 1778, he describes how Parisian allegros tended to begin with everyone playing together; he therefore began his finale differently—softly, with only the two violin parts for the opening bars—before unleashing a full-force entrance designed, as he openly admits, to make an effect [5]. That detail is more than an anecdote: it tells us Mozart was composing with the social acoustics of Paris in mind (habits of listening, habits of applauding, and the “grammar” of what counted as an event).
The slow movement became an interpretive battleground almost immediately. Mozart originally wrote an Andantino (in 6/8), but after feedback—often linked to Legros’s complaint that the movement was too long—he composed a replacement Andante (in 3/4), shorter and (on first hearing) more straightforward [2]. Mozart, however, pushes back against the criticism in his subsequent correspondence, insisting the movement was “very short” despite what Legros said—an unusually sharp glimpse of artistic pride under commercial pressure [6]. The result is that K. 297 is not a single frozen text but a symphony with an early performance history embedded in its very materials: one city, one season, two slow movements, and the practical question of what would satisfy a paying public.
Instrumentation
K. 297 is often described (accurately) as a “big orchestra” symphony for its time—yet its scoring is also strategic. Mozart writes brilliance into the outer movements while thinning the middle movement’s palette for contrast.

- Winds: 2 flutes, 2 oboes, 2 clarinets, 2 bassoons
- Brass: 4 horns, 2 trumpets
- Percussion: timpani
- Strings: violins I & II, viola, cello, double bass
This is the instrumentation reflected in modern critical-performance materials and study editions, which often describe the wind set in “Paris” terms as unusually expansive—especially the presence of clarinets and four horns, which enlarge the harmonic “halo” around tuttis and help explain the symphony’s distinctive gleam in D major [7].
Yet Mozart also withholds. The slow movement’s scoring, in many performances and discussions, is treated as a deliberate “deglamorization”: clarinets, trumpets, and timpani drop out, creating a chamber-like interior after the public brilliance of the opening [8]. This is not merely a concession to taste; it is a structural principle. The symphony’s emotional profile depends on the listener feeling the distance between Parisian spectacle and Mozartian song.
Form and Musical Character
I. Allegro assai (D major)
The first movement’s opening is a lesson in how Mozart could make “public” rhetoric serve symphonic logic. The slow introduction that would become typical in later Paris symphonism is absent; instead Mozart begins with immediate ceremonial confidence and then proceeds by sharply profiled blocks: bright tutti proclamations, quick transitions, and wind writing that is not just color but a participant in the argumentative flow.
What can sound, on a superficial first listen, like pure brightness is in fact tightly managed contrast. The clarinets and horns thicken the mid-register and allow Mozart to articulate harmonic turns with a new kind of weight; the trumpets and timpani underline cadences with a festive authority that is as theatrical as it is architectural. One may hear, behind the surface, Mozart’s practical goal: the movement must “read” in a large hall with a mixed audience. But one may also hear Mozart’s deeper goal: to turn that readability into a form that feels inevitable.
II. Andante (G major, 3/4) — alternative to the earlier Andantino (6/8)
The slow movement is where the “Paris” Symphony most clearly reveals its negotiation with circumstance. The existence of two versions is not a mere curiosity; it changes how one understands Mozart’s Paris aesthetic. The earlier Andantino (6/8) is often described as more ambitious—longer-breathed, more mobile harmonically—while the replacement Andante (3/4) compresses the material and reduces the sense of wandering.
Mozart’s letters suggest a composer both accommodating and resistant: accommodating enough to rewrite, resistant enough to contest the premise that the movement was “too long” [6]. Modern discussions sometimes frame this as a conflict between “serious” symphonic thinking and a supposedly superficial Parisian public. The truth is subtler. Paris did not reject complexity as such; it demanded that complexity be staged as an immediately graspable event. The replacement Andante may therefore be heard not as capitulation but as Mozart’s experiment in clarity: fewer “detours,” a more direct cantabile line, and a transparency that makes the central movement function as an oasis between two extrovert panels [8].
III. Allegro (D major)
The finale is Mozart’s most overt piece of audience psychology in the symphony. In his own account, he deliberately avoided the local habit of beginning an allegro with the full orchestra in unison; instead, he starts softly with the violins alone and then triggers a sudden forte entrance—an effect he knew could provoke immediate excitement [5].

This “surprise” is not gimmickry, because Mozart integrates it into the movement’s long-range energy. The quick alternations of texture—string-driven passages, then full orchestral assertions—create a sense of momentum that is both physical (one feels the orchestra “arrive”) and formal (one feels the music tightening toward closure). The movement’s wit also lies in how it controls repetition: figures return, but often with redistributed orchestration, as if Mozart were continually adjusting the spotlight across the ensemble.
Reception and Legacy
By Mozart’s own testimony, the symphony succeeded. He reports strong approval and describes the kind of audible public response—applause at striking moments—that confirms the work met Paris on its own terms [5]. It also entered a wider European circulation quickly: the work was published in Paris by Jean-Georges Sieber and then resurfaced in later performance contexts beyond France, including Vienna in the early 1780s [1].
In the longer view, the “Paris” Symphony’s importance is twofold. First, it marks a decisive step in Mozart’s orchestral imagination: not just more instruments, but a more public-facing handling of form—music that can dazzle without losing structural poise. Second, it preserves, almost like a documentary trace, Mozart’s lived experience of a modern concert marketplace: a director’s request, rehearsal anxieties, audience reactions, and even the revision of an entire slow movement. Few Mozart symphonies allow us to watch the work being shaped so directly by a specific city’s taste—and to see Mozart, at 22, learning how to turn taste into art without surrendering his own standards.
