Blues musical styles, forms (12-bar blues), melodies, and the blues scale have influenced many other genres of music, such as rock and roll, jazz, and popular music.[117] Prominent jazz, folk or rock performers, such as Louis Armstrong, Duke Ellington, Miles Davis, and Bob Dylan have performed significant blues recordings. The blues scale is often used in popular songs like Harold Arlen's "Blues in the Night", blues ballads like "Since I Fell for You" and "Please Send Me Someone to Love", and even in orchestral works such as George Gershwin's "Rhapsody in Blue" and "Concerto in F".
