Belgium, Spain, and Italy. By 1856 the French Garde Republicaine band included eight saxophones, making it the largest ensemble to prominently feature the instrument. The saxophone was used experimentally in orchestral scores, but never came into widespread use as an orchestral instrument. In 1853-54 the orchestra of Louis Antoine Jullien featured a soprano saxophone on a concert tour of the United States. After an early period of interest and support from classical music communities in Europe, their interest in the instrument waned in the late nineteenth century. Saxophone teaching at the Paris Conservatory was suspended from 1870 to 1900 and classical saxophone repertoire stagnated during that period. But it was during this same period that the saxophone began to be promoted in the United States, largely through the efforts of Patrick Gilmore, leader of the 22nd Regiment band, and Edward A. Lefebre, a Dutch emigre and saxophonist with family business associations with Sax. Lefebre settled in New York in early 1872 after he arrived as a clarinetist with a British opera company. Gilmore organized the World Peace Jubilee and International Music Festival taking place in Boston that summer. The Garde Republicaine band performed and Lefebre was a clarinetist with the Great Festival Orchestra for that event. In the fall of 1873 Gilmore was reorganizing the 22nd Regiment band under the influence of the Garde Republicaine band and recruited Lefebre, who had established a reputation in New York as a saxophonist over the previous year. Gilmore's band soon featured a soprano-alto-tenor-baritone saxophone section, which also performed as a quartet. The Gilmore-Lefebre association lasted until Gilmore's death in 1892, during which time Lefebre also performed in smaller ensembles of various sizes and instrumentation, and worked with composers to increase light classical and popular repertoire for saxophone. Lefebre's later promotional efforts were extremely significant in broadening adoption of the saxophone. Starting towards the end of the 1880s he consulted with the brass instrument manufacturer C.G. Conn to develop and start production of improved saxophones to replace the costly, scantly available, and mechanically unreliable European instruments in the American market. The early 1890s saw regular production of saxophones commence at Conn and its offshoot Buescher Manufacturing Company, which dramatically increased availability of saxophones in the US. Lefebre worked with the music publisher Carl Fischer to distribute his transcriptions, arrangements, and original works for saxophone, and worked with the Conn Conservatory to further saxophone pedagogy
