Capriccio in C major for Piano, K. 395 (K. 300g)
볼프강 아마데우스 모차르트 작
Mozart’s Capriccio in C major (K. 395; also catalogued as K. 300g and closely linked with K. 284a) belongs to his Munich period of 1777–78 and preserves, in written form, the sort of brilliant keyboard improvisation for which contemporaries admired him.[1][2] Though compact and less famous than the later fantasies, it offers an illuminating glimpse of Mozart at 21–22: experimenting with prelude-like textures, quick changes of figuration, and a performer’s instinct for rhetorical surprise.[1]
Background and Context
Mozart’s Munich stay in the autumn of 1777 falls in the restless interval between his Salzburg employment and the decisive break that would lead him to Vienna. In these years he was eager to be heard as a keyboard virtuoso, and his letters and contemporary reports repeatedly point to his gift for improvisation—especially in preludes, transitions, and varied re-statements of material. The Capriccio in C major, K. 395 is best understood in that light: it is not a “caprice” in the later Romantic sense, but a written trace of an improviser’s craft—brilliant passagework, sudden textural shifts, and a freedom that sits somewhere between prelude and variation practice.[1]

The work also matters historically because its identity was clarified only relatively late in modern scholarship. In the New Mozart Edition it appears as the Prelude in C, K. 284a, “known as Capriccio K. 395/300g,” reflecting the fact that materials once circulating under different titles and catalogue numbers are now treated as one and the same composition.[1] This dual naming explains why older recordings and editions may list it as Capriccio (K. 395) while newer catalogues and releases often prefer Four Preludes (K. 284a).
Composition
Most modern reference and editorial materials place the piece in Munich around October 1777, i.e., when Mozart was 21; Köchel’s ninth edition (K6/K9 traditions reflected in many catalogues) also keeps it in the Munich orbit of 1777–78, with cross-references to the older number K. 300g.[1][2][3] Because Mozart’s early keyboard miniatures were not always dated as precisely as his later Vienna works (which he catalogued systematically from 1784), some sources still give “1778” in summary listings; the safest formulation is that K. 395 belongs to the Munich period of late 1777 to early 1778.[3][4]
The editorial report for the New Mozart Edition further notes that part of the autograph transmission involves a page held by the Pierpont Morgan Library (New York), a small but telling reminder that even modest-seeming keyboard pieces can have complex source histories.[1]
Form and Musical Character
Despite the traditional title Capriccio, the music behaves like an organised chain of prelude- or variation-like spans: short, clearly articulated ideas that return in altered guise, moving rapidly between chordal rhetoric and filigree. What makes the piece distinctive within Mozart’s keyboard output of the late 1770s is its emphasis on process—how a figuration is spun out, intensified, redirected—rather than on a long, cantabile melody as the central “theme.”
Listeners will notice several “public” virtuoso fingerprints:
- Bright C-major fanfare energy at the opening, anchoring the ear before Mozart begins to decorate.
- Quick alternations of chordal writing (a performer’s proclamation) and running figuration (a performer’s display).
- A prelude-like sense of harmonic roaming, in which the delight comes from the journey through textures and keys as much as from arrival points.
In other words, K. 395 deserves attention not because it is a hidden “masterpiece” on the scale of the later Fantasia in C minor, K. 475, but because it shows Mozart formalising improvisational practice in a way that helps explain his later freedom with large-scale forms: the instinct to juxtapose, transform, and re-colour ideas quickly—yet always with classical clarity of cadence and proportion.[1]
Reception and Legacy
K. 395 has long lived a double life in print and performance. Older catalogues and some editions present it straightforwardly as a Capriccio (K. 395 / K. 300g), while modern editorial practice often folds it under K. 284a as the Prelude(s) in C—a shift that subtly changes how performers frame it (as “character piece” versus “prelude set”).[1][2]
Today the work is a rewarding choice for pianists and listeners interested in Mozart beyond the greatest hits: it is short, brilliant, and surprisingly revealing about his keyboard rhetoric in the years just before his mature Vienna style. In recital it can function as an opener—something like a poised, Classical curtain-raiser—while in study it invites a deeper question: how much of Mozart’s art is “composed,” and how much is the disciplined preservation of an improviser’s imagination?
