A now standard component of orchestral and wind band repertoire, Symphonic Metamorphosis of Themes by Carl Maria von Weber was originally intended to be ballet music. This study examines the history and background surrounding Paul Hindemith's orchestral piece and demonstrates how Hindemith crafted each movement based off Weber's original piano duets and incidental orchestral music. The study was undertaken as limited information exists about the piece in its entirety, and much of what has been written primarily concerns itself with grammatical and contextual aspects of Hindemith's title. Existing analyses either only focus on a singular movement, or are limited; presumably, due to a prevailing notion that Hindemith simply orchestrated the piano pieces. Potentially exacerbating the issue may be the fact that it was not known for nearly twenty years after Symphonic Metamorphosis was premiered which Weber duets Hindemith reworked. This analysis, coupled with the background information provided, shows that Hindemith's settings transcend mere orchestrations and, in some cases, exhibit qualities of original composition. The analysis thoroughly delineates Weber's Turandot overture and three piano duets, part by part and hand by hand, to show exactly where and how Hindemith altered the original writings. The differences in overall form, measure numbers, tempi, meter, and harmony are listed. In addition, it is revealed which thematic additions, alterations, and omissions Hindemith includes.
