Carl Gottlieb Reissiger was a successful German composer, conductor, and teacher in the first half of the nineteenth century. At the height of his career, he was Hofkapellmeister of theater and opera in Dresden, a position he held until his death. He was a composer of more than 200 works in a multitude of different genres. Today he is mainly known as a composer of opera, a small portion of his total output as a composer. He wrote approximately eighty piano solos, eighty collections of songs or duets, nine masses, and many smaller sacred choral works, as well as 27 piano trios, seven piano quartets, and three piano quintets. In addition to these many works, he wrote five works for the clarinet: Concertino, op. 63, Duo Brillant for clarinet and piano, op. 130, Fantasie, op. 146, Second Fantasie, op. 180, and Adagio und Rondo alla polacca, op. 214. This document provides a biographical sketch of Reissiger, including his personal life, his life as a conductor, and his life as a composer. It also provides a look at the artistic life of his day: his fellow composers and the music they were writing for clarinet, outstanding clarinetists and the different instruments they were playing. The aim of this study is to provide a stylistic analysis of Reissiger's five works for clarinet, including a discussion of form, melody, harmony, and rhythm. This document puts forth the proposal that these works are worth resurrecting and that Reissiger, as a composer of clarinet music, is more than just a secondary composer.
