Symphonic Metamorphosis of Themes by Carl Maria von Weber is an orchestral work written by German composer Paul Hindemith in America in 1943. History The idea of composing a work based on Carl Maria von Weber's music was first put to Hindemith in 1940 by the choreographer and dancer Léonide Massine, who suggested that he should arrange music by Weber for a ballet. When Hindemith made a piano arrangement in March 1940 of the two pieces that would become movements 1 and 3 of the Metamorphosis (which in a letter of April 12, 1940 he described as "lightly coloured and made a bit sharper"), Massine expressed a preference for more strict arrangements of Weber. This was one reason the project fell through. After studying Weber's music, Hindemith watched one of Massine's ballets and disliked it, and so wrote the Symphonic Metamorphosis instead. The Andantino and Marsch were completed on June 8 and June 13, 1943, respectively, and the manuscript of the complete orchestral score is dated August 29, 1943. Although by its thematic material it belongs squarely in the European tradition, it was composed with the virtuosity of American symphony orchestras in mind, and was titled originally in English. Other hands later translated it variously into German as Symphonische Metamorphose von [über/nach/zu] Themen Carl Maria von Webers; two German editions mistakenly give the title in the plural, Sinfonische Metamorphosen nach Themen von Carl Maria von Weber, and Sinfonische Metamorphosen Carl Maria von Weber’scher Themen, though none of these German titles were sanctioned by Hindemith. They nevertheless have sometimes been back-translated into English as Metamorphoses on Themes by .... The work is also sometimes known in English as Symphonic Variations on (or of) Themes by Carl Maria von Weber but, despite the title's reference to "themes", the work incorporates material more broadly from whole works by Weber. The Symphonic Metamorphosis is in four movements: Allegro Scherzo (Turandot): Moderato – Lively Andantino Marsch The Weber themes are taken from incidental music which Weber wrote for a play by Carlo Gozzi, based on the same Turandot legend that later inspired Giacomo Puccini and others. Hindemith and his wife would play Weber's music for piano four-hands, and Hindemith used some of these little-known pieces—Op. 60/4 (no. 253 in the Jähns catalog of Weber's works) (first movement), Op. 37 (J. 75) (second movement), Op. 10/2 (J. 82) (third movement), and Op. 60/7 (J. 265) (fourth
