"To the artists"—these were the words Niccolò Paganini attached to his 24 Caprices (a set of études for solo violin), the only work he published for solo violin in his lifetime. Whether or not Paganini intended it as such, the dedication reads almost like a gauntlet thrown down before the composers and performers of his time. There is no record that he ever played these pieces before an audience, yet the shock his playing delivered to his contemporaries was immense. Schumann abandoned the path of a jurist to choose a life in music; Liszt withdrew from public view for a time, immersing himself in the study of Paganini's playing, its application to the piano, and the improvement of his own technique. From Schumann, Liszt, and Brahms down to Rachmaninoff a century later, the answers to the challenge Paganini posed run like a thread through the whole history of classical music. This essay traces how that challenge was received and answered, focusing on the Paganini theme taken up by so many later composers—the most famous of the 24 Caprices, the twenty-fourth. --- ## Caprice No. 24 in A minor Niccolò Paganini's Caprice No. 24 in A minor crowns the *24 Caprices for Solo Violin*, Op. 1. Op. 1 is the only collection of his own solo-violin music that Paganini brought before the public, and its composition preceded its publication. Unlike the other twenty-three, the final caprice is itself cast in variation form: a concise, unforgettable theme in A minor followed by eleven variations and a closing passage. The theme is built upon an extremely simple harmonic frame—an almost skeletal progression that returns firmly to the tonic. Yet it is precisely this plainness that made the theme inexhaustible as material for variation. Striking enough to remain recognizable under any disguise, yet harmonically so open as to admit almost any treatment, it is an ideal subject for variation. It took many years for these twenty-four pieces to be gathered into a single volume. Because no reliable chronology of autograph manuscripts survives, the dating of their composition remains a matter of debate, but they are generally thought to have been written across the period from roughly 1802 to 1817—in particular during Paganini's years at the court of Lucca (1805–1809), where he served Elisa Baciocchi, Napoleon's sister. There was a precedent: Pietro Locatelli's *L'arte del violino*, published in 1733, likewise contained twenty-four caprices. But Paganini went beyond the bounds of such pedagogical pieces, crystallizing a wide range of techniques—double stops, leaps of an octave and a tenth, artificial harmonics, ricochet and spiccato bowing—each into a self-contained piece of music. In bringing the collection before the world in 1820, Paganini dedicated it not to a wealthy aristocrat but "to the artists" (*agli artisti*). It was a gesture that refused the convention of dedication in expectation of reward, and at the same time a gauntlet thrown down before the performers of his day. The reach of these caprices, however, owes as much to the myth surrounding their author as to the notes themselves. The caprices had been in print since 1820, but what turned Paganini into a continental phenomenon was a single sequence of events: the European tour of 1828 to 1834. Beginning in Vienna and moving through Germany, Poland, Paris, and England, the tour left stunned young musicians in its wake. Audiences half believed the rumor that this violinist had sold his soul to the devil. This "demonic" image was no single superstition but was formed from several interrelated yet distinct cultural frameworks layered upon one another—a pact with the devil, demonic possession, and Gothic moral corruption (Kawabata 2007). The diabolical reputation eventually drew in a further slander of miserliness that dogged him even after his death, though there is also scholarship arguing that the truth was rather the opposite—as shown by his free charity concerts for cholera victims and orphans, and by the words carved on his tomb in Parma, "a heart of boundless generosity" (Výborný 1961). --- ## Robert Schumann — *Studies after Paganini's Caprices* Of the composers traced here, Schumann's encounter came earliest, and it changed the very course of his life before he ever touched this particular theme. Having heard Paganini in Frankfurt on Easter Sunday of 1830, the law student Schumann wrote in his diary that in Paganini's hands "the driest study blazes up like a Pythian oracle." Soon after, he told his mother of his resolve to abandon law for music. His mother was at first skeptical of this decision and, to gauge her son's prospects, sought the opinion of the Leipzig teacher Friedrich Wieck. When Wieck assured her that within three years Robert could become a first-rank virtuoso, she reluctantly relented. Ironically, however, Schumann himself never walked the path of the virtuoso. A punishing practice regimen aimed at matching Paganini's velocity took its toll, and around 1832 he injured his right hand—the middle finger in particular—cutting off his future as a pianist (the cause remains unsettled, with explanations ranging from the use of a finger-strengthening device to focal dystonia). For Schumann, barred from playing himself, the project of transcribing the caprices for piano became a way of sublimating his thwarted ambitions as a performer into another form. That project bore fruit in the six *Studies after Paganini's Caprices*, Op. 3 (1832), and the six *Concert Studies*, Op. 10, that followed. Whereas Liszt would later recreate the caprices as brilliant spectacle, Schumann's aim was more inward and different in kind: not to maximize the display of technique but to draw out their poetry, often paring down the violin original and filling it instead with intimate feeling. His Op. 3 and Op. 10 are based on various caprices (not chiefly No. 24) and belong, alongside *Papillons* and *Carnaval*, to his earliest published works. Paganini held him for the rest of his life: in his final years, Schumann worked on adding piano accompaniments to the *24 Caprices*. The 1830s, when Schumann turned to these transcriptions, were also a time when young composers vied to become a "Paganini of the piano," competing over how to carry the violin's transcendent virtuosity onto the keyboard (Kregor 2013). --- ## Franz Liszt — *Grandes études de Paganini*, S.141 If Schumann drew the caprices inward, Liszt—struck by the same tour a year later—pushed them outward, toward a public, transcendent virtuosity that could fill a concert hall. Yet to dismiss this as a mere descent into spectacle would be too one-sided. His 1832 encounter with Paganini in Paris was, by Liszt's own account, a turning point. He resolved to achieve on the piano a technical revolution to match what Paganini had accomplished on the violin. In a famous letter from this period he records practicing thirds, sixths, octaves, tremolos, and repeated notes for hours every day, vowing that "unless I go mad, you will find an artist in me." This self-imposed seclusion flowed directly into his Paganini project. Its first fruit was not an étude but the *Grande fantaisie de bravoure sur La Clochette* (S.420), written in 1832 on the "little bell" rondo from Paganini's Violin Concerto No. 2—the seed of what would become "La Campanella." The first complete set of six followed in 1838 (*Études d'exécution transcendante d'après Paganini*, S.140), which he revised in 1851, during his Weimar years, into the definitive *Grandes études de Paganini* (S.141). Five of the six are based on the caprices; the famous No. 3, "La Campanella," is the exception, deriving from the finale of the same concerto just mentioned. No. 6 (in A minor)—marked *Quasi presto a capriccio*—takes up Caprice No. 24 directly, preserving Paganini's theme, eleven variations, and coda while translating the violin's idiom into cascading octaves, rapid scales and arpeggios, and delicate ornamentation in the high register. The 1851 revision streamlined the near-unplayable texture of the first version, removing every stretch greater than a tenth and producing music idiomatic to the piano while keeping Paganini's design. Liszt dedicated the collection to Clara Schumann. Liszt's engagement with the collection did not end at No. 24. He returned again and again to Caprice No. 1 (in E major) in particular, transcribing it for piano several times (Perry 2004). What he drew from Paganini was not merely a vocabulary of cascading virtuosity. The musicologist Jeffrey Perry points out that the harmonic motion found in this First Caprice—wandering searchingly from the tonic to remote keys and erasing every trace of the structural dominant—prefigured the cyclical formal schemes used later in the century by Liszt himself and by Wolf (Perry 2004). What Liszt found in these caprices was not only feats of finger dexterity but a harmonic thinking that overstepped the bounds of tonality. Indeed, for Liszt the imitation of the violin was no mere stunt: virtuosity was always a means of expression, never an end in itself (Kregor 2013). --- ## Johannes Brahms — *Variations on a Theme of Paganini*, Op. 35 A generation after Liszt, this brilliant idiom found an unexpected new bearer. Brahms returned to the Caprice No. 24 in particular, and to the principle of variation that Paganini had embedded within it. Composed in Vienna in 1862–63 and published in two books, each containing fourteen variations, the work bore the title "Studies for Pianoforte." This shows that, like Liszt, Brahms too treated the theme as a vessel for exploring the very limits of piano technique. He dedicated it to Carl Tausig, one of Liszt's finest pupils and a master pianist, writing with Tausig's transcendent ability in mind. Its difficulty became notorious. Clara Schumann, ordinarily a staunch champion of Brahms's music, called it the "Witch's Variations" (*Hexenvariationen*), and Tausig himself wrote to Brahms that he had "had a terrible time" with the piece and that everyone considered it unplayable. Even Eduard Hanslick, a critic of Brahms's own camp, described it as "studies for the hands that could drive the player out of his mind." There is a quiet irony in the dedication. Brahms was an emblematic figure of the conservative "absolute music" camp in the aesthetic "War of the Romantics" of the age. This dispute lay between those who, like Hanslick, held that instrumental music generates meaning through its form alone, and the progressive "New German School" of Liszt and Wagner, who bound music to poetry, narrative, and program. That Brahms, using a theme Liszt too had taken up, should so masterfully command the brilliant idiom that was the dedicatee's home ground shows how partisan strife played out upon a shared inheritance. Liszt knew the result and praised it. He is said to have remarked that Brahms's variations were better than his own, adding that his had come first—an anecdote that circulates, though without firm documentation. --- ## Sergei Rachmaninoff — *Rhapsody on a Theme of Paganini*, Op. 43 The composers up to this point all wrote for solo piano. The theme's most famous afterlife arrived a century after Paganini's death—and carried the melody out of the soloist's hands and into the orchestra. In 1934, at his villa "Senar" near Lucerne in Switzerland, Rachmaninoff completed the work between 3 July and 18 August. At the end of the manuscript he wrote "God bless." Titles such as *Symphonic Variations* and *Fantasia* were considered at first, but he settled finally on the French *Rhapsodie*—the last time he would use a French title. The premiere took place that same year, on 7 November, in Baltimore, Maryland, with Rachmaninoff himself as piano soloist and Leopold Stokowski conducting the Philadelphia Orchestra. Where his predecessors had written for solo piano, Rachmaninoff wrote his twenty-four variations for piano and orchestra. Formally a single movement, the work divides by key into four groups and, as a whole, follows the fast–slow–fast tempo scheme of a concerto. One of its defining strokes is a structural wit: like Beethoven at the opening of the finale of the *Eroica* Symphony, Rachmaninoff places the first variation before the statement of the theme, presenting at first only its harmonic skeleton. The theme, therefore, shows its bare face only after the variations have begun. The other, and best known, stroke is the eighteenth variation. Appearing in D-flat major in a complete reversal of the dark character that precedes it, this variation inverts Paganini's melody (turning its ascending line into a descending one), shifts it to the major, and slows it to an *Andante cantabile*. Though its material derives entirely from the caprice's theme, it sounds like an utterly new melody. Rachmaninoff himself is said to have remarked of this variation, "This one is for my agent"—he had seen that it would intoxicate audiences. Rachmaninoff also fused Paganini's melody with the *Dies irae*—the medieval Gregorian chant from the Mass for the Dead that sings of the Last Judgment. Ever since Berlioz used it in the *Symphonie fantastique*, this melody had become, in nineteenth-century music, a symbol of death and demonic power, and Rachmaninoff returned to it throughout his life in works such as *The Isle of the Dead*, *The Bells*, and the *Symphonic Dances*. In the Rhapsody it first appears in the seventh variation; in the tenth, the solo piano hammers it out in march-like fashion to form the climax of the first group; and at the close, in the twenty-fourth variation, it returns blazing in the brass. Some years after composing the work, when the choreographer Mikhail Fokine wished to make a ballet, Rachmaninoff proposed this Rhapsody and sent him, by letter, an outline of a scenario. It was based on the legend that Paganini sold his soul to an evil spirit for perfection in his art and for the love of a woman. All the variations containing the *Dies irae* represent the evil spirit, while the central section from the eleventh through the eighteenth variation represents the love episodes. Paganini himself first appears in the "Theme," is defeated, makes his last appearance in the twenty-third variation, and from there to the end belongs to the triumph of those who have vanquished him (Harrison 2005). Fokine's ballet *Paganini* was premiered in 1939 at Covent Garden in London. The premiere was received with enthusiasm, and within a year of its appearance the work had established itself in the standard repertoire. So immediate was its success that Rachmaninoff himself confessed his unease, remarking that to be liked by everyone at once was somehow suspicious. What binds these works together is neither school nor style, but a single melody and the one figure who stands behind it. The Caprice No. 24 has drawn an unbroken lineage of composers—at its longest reach, Liszt, Schumann, Brahms, Rachmaninoff, and beyond them Boris Blacher, Witold Lutosławski, Andrew Lloyd Webber, and dozens more—precisely because its plain, recognizable contour survives any transformation. For a century, this theme has been a vessel for Lisztian spectacle, for Schumannesque poetry, for Brahmsian rigor, and for Rachmaninoff's late-Romantic lyricism. The Caprice No. 24 lives on because it is at once a completed destination and a material that continues to invite rewriting. --- ## Sources - Maiko Kawabata, "Virtuosity, the Violin, the Devil… What Really Made Paganini 'Demonic'?," *Current Musicology*, No. 83 (2007), pp. 85–108 - Jonathan Kregor, "Forging 'Paganinis of the Piano' in the 1830s," *Studia Musicologica*, Vol. 54, No. 2 (2013), pp. 115–133 - Jeffrey Perry, "Paganini's Quest: The Twenty-four Capricci per violino solo, Op. 1," *19th-Century Music*, Vol. 27, No. 3 (Spring 2004), pp. 208–229 - Zdeněk Výborný, "The Real Paganini," *Music & Letters*, Vol. 42, No. 4 (Oct. 1961), pp. 348–363 - Max Harrison, *Rachmaninoff: Life, Works, Recordings* (London: Continuum, 2005)
