This study investigates and documents tenor/bass trombone solo performances at the Gewandhaus, Leipzig, East Germany, between 1821 and 1876. Included is the discussion of a newly discovered composition, the Concertino fur Bassposaune und Orchester, by Carl Heinrlch Meyer, which is the earliest concerto for the tenor/bass trombone. Its performance at the Gewandhaus in 1821 marked the beginning of the solo tradition for the tenor/bass trombone, and the Leipzig Gewandhaus became one of the leading centers of solo trombone performance for the next fifty years. The study includes background information on the rise of the virtuoso soloist in nineteenth-century Germany. It specifically focuses on Friedrlch August Belcke and Carl Traugott Queisser and their performances at the Gewandhaus. All solo trombone performances at the Gewandhaus in the nineteenth century have been documented, and specific information has been provided regarding the soloists, dates of performances and repertoire performed on the concerts. The paper includes a discussion of performance reviews from the Allgemeine Musfkalische Zeitung. The conclusion discusses the importance of solo trombone performance at the Gewandhaus, and the reason for its sudden decline after 1876.
