“Love’s Theme” is an instrumental piece recorded by Barry White’s Love Unlimited Orchestra and released in 1973 as an A-Side single. It is one of the few instrumental and purely orchestral singles to reach number one on the Billboard Hot 100 chart in the United States, which it did in early 1974.
Billboard ranked it as the No. 3 song for 1974. The piece was included on two albums: 1973’s Under the Influence of… Love Unlimited (by the vocal group Love Unlimited) and 1974’s Rhapsody in White by Love Unlimited Orchestra.
The recording, with a large string orchestra, wah-wah guitar, and big rhythm, is considered by author Peter Shapiro to be an influence to the disco sound, which would explode in popularity the following year. The song was also popular on the Adult Contemporary chart in the U.S., where the song spent two weeks at #1. It was also used by ABC Sports for many years as the opening theme music for its golf coverage.
New York television station WPIX used it as the closing music for its then-Action News franchise during the mid-1970s. In Canada, the single saw similar success, reaching #1 on the RPM 100 National Singles Chart on March 2, 1974. Wiki
