William Lovelock (13 August 189926 June 1986) was an English classical composer and pedagogue.
Lovelock was born in London and educated at Emanuel School and at Trinity College of Music, where he studied with C. W. Pearce and Henry Geehl. After service as an artilleryman in World War I, he returned to Trinity College, as a teacher and examiner. He was also private organist to Viscountess Cowdray from 1923 to 1926. In 1926, he married Winifred Irene Littlejohn. He obtained a doctorate in composition from the University of London in 1932. Between 1939 and 1946 he lived in India, eventually joining the Indian Army and reaching the rank of major in 1942. Returning to London in 1946, he rejoined the faculty at Trinity College before becoming Dean of the Faculty of Music at the University of London in 1954.
Two years later, Lovelock was appointed as the first Director of the Queensland Conservatorium of Music in Brisbane, Australia. In 1959 he left that position to become a free-lance teacher, composer, adjudicator, and the chief music critic for The Courier-Mail newspaper. He wrote numerous textbooks on music harmony and theory. He also wrote "Snowy River, Roll", a song requested by Sir William Hudson of the Snowy Mountains Scheme to promote unity in the Scheme's work camps.
Lovelock's music compositions included several teaching pieces for children, and fourteen concertos. He wrote more than twenty music theory textbooks, including the undated First Year Harmony, Second Year Harmony, Third Year Harmony, A Concise History of Music (London, 1953), and Rudiments of Music (London, 1957)
