Percy Faith (April 7, 1908 – February 9, 1976) was a Canadian–American bandleader, orchestrator, composer and conductor, known for his lush arrangements of instrumental ballads and Christmas standards. He is often credited with popularizing the"easy listening" or"mood music" format. He became a staple of American popular music in the 1950s and continued well into the 1960s. Although his professional orchestra-leading career began at the height of the swing era, he refined and rethought orchestration techniques, including use of large string sections, to soften and fill out the brass-dominated popular music of the 1940s.
