Glenn Miller and His Orchestra was an American swing dance band formed by Glenn Miller in 1938. Arranged around a clarinet and tenor saxophone playing melody, and three other saxophones playing harmony, the band became the most popular and commercially successful dance orchestra of the swing era and one of the greatest singles charting acts of the 20th century. Miller's short-term chart successes have seldom been duplicated and his group's unprecedented dominance of early Your Hit Parade and Billboard singles charts, including 16 number-one singles and 69 Top Ten hits.
