Question: Which genre did the only true successor to Chopin (according to J. Barrie Jones) compose?

full_context: Document 1: Mohamed Nagui: Over the course of his life, Nagui's artistic style varied, going from writing poems to writing novels. Yet, his works share the common theme of being about the human experience and connecting with nature. His works sometimes took on a political undertone - one of his most well-known works, the 2008 novel "El-Effendi" (also transliterated as "al-Affandi", or just ""Effendi"" in English), for example, was a "criticism of [a] middle class obsessed with chasing monetary and personal gain at the expense of the nation and society." Yet, even with this story, Nagui resisted the temptation to produce purely political works, with one critic noting how: "On the surface, Mohamed Nagui's The Effendi looks like another one of those anger-laden books about the corruption eating contemporary Egypt from the inside out...[But] Nagui uses the by now cliched template of the Egyptian young man who snakes his way up using unethical short-cuts and sleight-of-hand, and turns it over its head by writing something closer to a modern fairytale." In his works, Nagui shows a special affinity for the city of Alexandria, with one author noting how he and other "Proto-Modernists" like Mahmoud Said used Alexandria, "that most promiscuous of cities", as a model for what constitutes "Egyptianness". To date, Nagui remains widely regarded as one of the most influential writers to have ever come from the pan-Arab region.
Document 2: Translation: When a historic document survives only in translation, the original having been lost, researchers sometimes undertake back-translation in an effort to reconstruct the original text. An example involves the novel The Saragossa Manuscript by the Polish aristocrat Jan Potocki (1761–1815), who wrote the novel in French and anonymously published fragments in 1804 and 1813–14. Portions of the original French-language manuscript were subsequently lost; however, the missing fragments survived in a Polish translation that was made by Edmund Chojecki in 1847 from a complete French copy, now lost. French-language versions of the complete Saragossa Manuscript have since been produced, based on extant French-language fragments and on French-language versions that have been back-translated from Chojecki’s Polish version.
Document 3: Frédéric Chopin: All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some songs to Polish lyrics. His keyboard style is highly individual and often technically demanding; his own performances were noted for their nuance and sensitivity. Chopin invented the concept of instrumental ballade. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, études, impromptus, scherzos, preludes and sonatas, some published only after his death. Influences on his compositional style include Polish folk music, the classical tradition of J. S. Bach, Mozart and Schubert, the music of all of whom he admired, as well as the Paris salons where he was a frequent guest. His innovations in style, musical form, and harmony, and his association of music with nationalism, were influential throughout and after the late Romantic period.
Document 4: Frédéric Chopin: Frédéric François Chopin (/ˈʃoʊpæn/; French pronunciation: ​[fʁe.de.ʁik fʁɑ̃.swa ʃɔ.pɛ̃]; 22 February or 1 March 1810 – 17 October 1849), born Fryderyk Franciszek Chopin,[n 1] was a Polish and French (by citizenship and birth of father) composer and a virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.
Document 5: Frédéric Chopin: Polish composers of the following generation included virtuosi such as Moritz Moszkowski, but, in the opinion of J. Barrie Jones, his "one worthy successor" among his compatriots was Karol Szymanowski (1882–1937). Edvard Grieg, Antonín Dvořák, Isaac Albéniz, Pyotr Ilyich Tchaikovsky and Sergei Rachmaninoff, among others, are regarded by critics as having been influenced by Chopin's use of national modes and idioms. Alexander Scriabin was devoted to the music of Chopin, and his early published works include nineteen mazurkas, as well as numerous études and preludes; his teacher Nikolai Zverev drilled him in Chopin's works to improve his virtuosity as a performer. In the 20th century, composers who paid homage to (or in some cases parodied) the music of Chopin included George Crumb, Bohuslav Martinů, Darius Milhaud, Igor Stravinsky and Heitor Villa-Lobos.
Document 6: Frédéric Chopin: Two of Chopin's long-standing pupils, Karol Mikuli (1821–1897) and Georges Mathias, were themselves piano teachers and passed on details of his playing to their own students, some of whom (such as Raoul Koczalski) were to make recordings of his music. Other pianists and composers influenced by Chopin's style include Louis Moreau Gottschalk, Édouard Wolff (1816–1880) and Pierre Zimmermann. Debussy dedicated his own 1915 piano Études to the memory of Chopin; he frequently played Chopin's music during his studies at the Paris Conservatoire, and undertook the editing of Chopin's piano music for the publisher Jacques Durand.
Document 7: King Roger: The "Sicilian drama", as he called it, originated from Szymanowski's enthusiasm for Mediterranean culture as a melting pot of different peoples and religions. He spent much time travelling in that area in 1911 and in 1914, and shared his love of the region with Iwaszkiewicz. In the summer of 1918 at Odessa, Ukraine, Szymanowski and Iwaszkiewicz conceived the project, and composed the opera over the period of 1918 to 1924. Szymanowski's lost novel "Efebos" dealt with mystical themes similar to those that inspired this work; Szymanowski labelled it a "Misterium".
Document 8: Frédéric Chopin: With his mazurkas and polonaises, Chopin has been credited with introducing to music a new sense of nationalism. Schumann, in his 1836 review of the piano concertos, highlighted the composer's strong feelings for his native Poland, writing that "Now that the Poles are in deep mourning [after the failure of the November 1830 rising], their appeal to us artists is even stronger ... If the mighty autocrat in the north [i.e. Nicholas I of Russia] could know that in Chopin's works, in the simple strains of his mazurkas, there lurks a dangerous enemy, he would place a ban on his music. Chopin's works are cannon buried in flowers!" The biography of Chopin published in 1863 under the name of Franz Liszt (but probably written by Carolyne zu Sayn-Wittgenstein) claims that Chopin "must be ranked first among the first musicians ... individualizing in themselves the poetic sense of an entire nation."
Document 9: Frédéric Chopin: Some modern commentators have argued against exaggerating Chopin's primacy as a "nationalist" or "patriotic" composer. George Golos refers to earlier "nationalist" composers in Central Europe, including Poland's Michał Kleofas Ogiński and Franciszek Lessel, who utilised polonaise and mazurka forms. Barbara Milewski suggests that Chopin's experience of Polish music came more from "urbanised" Warsaw versions than from folk music, and that attempts (by Jachimecki and others) to demonstrate genuine folk music in his works are without basis. Richard Taruskin impugns Schumann's attitude toward Chopin's works as patronizing and comments that Chopin "felt his Polish patriotism deeply and sincerely" but consciously modelled his works on the tradition of Bach, Beethoven, Schubert and Field.
Document 10: The Poem of Ecstasy: Alexander Scriabin's The Poem of Ecstasy ("Le Poème de l'extase"), Op. 54, is a symphonic poem written between 1905 and 1908, when Scriabin was actively involved with the Theosophical Society. It lasts about 20 minutes.
Document 11: Mitridate, re di Ponto: Mozart wrote "Mitridate" while touring Italy in 1770. The musicologist Daniel E. Freeman has recently demonstrated that it was composed with close reference to the opera "La Nitteti" by Josef Mysliveček. The latter was the opera being prepared for production in Bologna when Mozart met Mysliveček for the first time with his father in March 1770. Mysliveček visited the Mozarts frequently in Bologna during the summer of 1770 while Wolfgang was working on "Mitridate". Mozart gained expertise in composition from his older friend and also incorporated some of his musical motives into his own operatic setting. The opera was first performed at the Teatro Regio Ducal, Milan, on 26 December 1770 (at the Milan Carnival). It was a success, having been performed twenty-one times despite doubts because of Mozart's extreme youth – he was 14 at the time. No revival took place until the 20th century. This opera features virtuoso arias for the principal roles, but only two ensemble numbers: the act 2 ending duet between Aspasia and Sifare ("Se viver non degg’io"), and the brief quintet that ends the opera, very characteristic of standard baroque opera seria where the opera ends with a short "coro" or "tutti" number.
Document 12: Osip Senkovsky: Senkovsky was born into an old family of Polish szlachta. During his study in the University of Vilno he became fascinated with all things oriental. Having mastered the Arabic, Persian, Turkish, and Hebrew languages, he was assigned to the Russian mission in Constantinople, which occupation gave him ample opportunities to travel in Syria, Nubia, and Egypt. In 1821 he returned to the Russian capital, where he got the chair in oriental languages at the University of St Petersburg.
Document 13: Frédéric Chopin: Possibly the first venture into fictional treatments of Chopin's life was a fanciful operatic version of some of its events. Chopin was written by Giacomo Orefice and produced in Milan in 1901. All the music is derived from that of Chopin.
Document 14: Jerzy Żuławski: In a twenty-year writing career, from his first book of poems in 1895, at the age of 21, to his final World War I dispatches in 1915, Jerzy Żuławski created an impressive body of work—seven volumes of poetry, three collections of literary criticism, numerous cultural and philosophical essays, ten plays and five novels. He was considered an important and influential intellectual figure in the early years of the 20th century, but a century later, the only creation which has remained in print and assured him literary immortality is "The Lunar Trilogy". Stanisław Lem (1921–2006), renowned as the "most widely read science-fiction writer in the world", contributed an introduction to the 1956 and 1975 editions of the "Trilogy"'s initial volume, "Na Srebrnym Globie" ("On the Silver Globe"), crediting Żuławski's words with inspiring him to become "a writer of the fantastic" and describing the time he spent reading "The Lunar Trilogy" as "one of the most fascinating and life-changing experiences" of his youth.
Document 15: Frédéric Chopin: Four boarders at his parents' apartments became Chopin's intimates: Tytus Woyciechowski, Jan Nepomucen Białobłocki, Jan Matuszyński and Julian Fontana; the latter two would become part of his Paris milieu. He was friendly with members of Warsaw's young artistic and intellectual world, including Fontana, Józef Bohdan Zaleski and Stefan Witwicki. He was also attracted to the singing student Konstancja Gładkowska. In letters to Woyciechowski, he indicated which of his works, and even which of their passages, were influenced by his fascination with her; his letter of 15 May 1830 revealed that the slow movement (Larghetto) of his Piano Concerto No. 1 (in E minor) was secretly dedicated to her – "It should be like dreaming in beautiful springtime – by moonlight." His final Conservatory report (July 1829) read: "Chopin F., third-year student, exceptional talent, musical genius."
