In 1843, Italian composer G. Donizetti introduced Sax's bass clarinet in his opera "Don Sebastian," provoking opposition from the musicians of the Paris Opera, led by M. Carafa and the orchestra's principal clarinetist. This controversy reflected personal interests and the threat posed by Sax's innovations to the musicians of the time, as well as to traditional instrument manufacturers. The bass clarinet was ultimately removed from the score due to the strong opposition of the orchestra musicians.
