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

Faith was born and raised in Toronto, Ontario, Canada. He played violin and piano as a child, and played in theatres and at Massey Hall. After his hands were badly burned in a fire, he turned to conducting, and his live orchestras utilized the new medium of radio broadcasting. Beginning with defunct stations CKNC and CKCL, Faith was a staple of the Canadian Broadcasting Corporation's live-music broadcasting from 1933 to 1940, when he resettled in Chicago. In 1945, he became a naturalized citizen of the United States. He made many recordings for Voice of America. After working briefly for Decca Records, he worked for Mitch Miller at Columbia Records, where he turned out dozens of albums and provided arrangements for many of the pop singers of the 1950s, including Tony Bennett, Doris Day and Guy Mitchell (for whom Faith wrote Mitchell's number one single, "My Heart Cries for You").

His most famous and remembered recordings are "Delicado" (1952), "Song from the Moulin Rouge" (1953) and "Theme from A Summer Place" (1960), which won the Grammy Award for Record of the Year in 1961. Faith remains the only artist to have the best selling single of the year during both the pop singer era ("Song from Moulin Rouge") and the rock era ("Theme from a Summer Place"). The flip side of "Song from the Moulin Rouge" was the also popular and lovely "Swedish Rhapsody" by composer Hugo Alfvén.
