Professional musicians would often buy matched sets of clarinets that were made in different keys. This allowed the musician to choose the correct instrument for the music being performed while maintaining the same sound quality between the instruments.Since the early part of the nineteenth century, Munich had been a leading centre for the production of woodwind instruments. These high quality instruments were made by the firm of Osterreid & Gerlach, which was connected by family and training with the influential maker Ottensteiner. Ottensteiner, together with the clarinet virtuoso Carl Baermann, developed the system of clarinet represented here – the Ottensteiner-Baermann system.
Osterreid and Gerlach were established as a partnership between Anton Osterreid (1829-1912) and Gerlach in 1895. Osterreid trained in Paris and in 1852 migrated with his sister to America, but returned in 1860. He worked as a foreman for various firms before retiring in 1909, three years before his death.
