Hal Mooney, born Harold Mooney, (February 4, 1911 - March 23, 1995) was an American composer and arranger. 　　Hal Mooney was born in Brooklyn, New York. As a young man, Mooney was a professional pianist. He attended Brooklyn and St. John's Law Schools. After studying music under New York University professor Orville Mayhood and then under the influential Joseph Schillinger, he was invited to join the arrangers' roster for the popular Hal Kemp Orchestra, alongside John Scott Trotter (who was about to leave the band) and Lou Busch. 　　Mooney then moved to the Jimmy Dorsey Orchestra, but World War II was breaking out and soon he was called up by the United States Army. 　　In 1956, Mooney finally swapped freelancing for an exclusive contract, becoming in-house arranger and A&R Director at Mercury Records, where he would remain until the late 1960s. There, he provided arrangements for another raft of top singers, including Sarah Vaughan, Dinah Washington, Helen Merrill, Ernestine Anderson and, on Mercury's parent label, Philips Records, Nina Simone. 　　Mooney was described as a "nuts and bolts arranger" by fellow chart writer Billy May. It was meant as a compliment, and Mooney's versatility can be characterised by some of the more notable arrangements he wrote at the Mercury stable. 　　For Vaughan, he provided lush, string settings (along with more brassy, upbeat numbers) on albums such as Great Songs From Hit Shows (1956) and Sarah Vaughan Sings George Gershwin (1957). Though those arrangements grated with some jazz purists, their dramatic qualities inspired the acclaimed singer to some of her finest work, for example Hit Shows' "It Never Entered My Mind" and the Gershwin album's Isn't It a Pity?. Apart from such highbrow projects, Mooney also arranged some of Vaughan's forays into R&B-inspired 50s pop, for example the Clyde Otis-penned "Sweet Affection" (1957). 　　Mooney's numerous arrangements for Dinah Washington, meanwhile, ranged from straight big band swing, through Latin mambo to rhythm and blues, but the seven albums on which he worked with Simone, between 1964 and 1967, display the greatest versatility. Though they contain the occasional string-backed track not unlike Mooney's classic work with Vaughan, they took him a world away from it at other times. For example, Simone's final Philips album, High Priestess of Soul (1967), is a diverse combination of pop, jazz and gospel. Mooney's two best-known arrangements for Simone, "I Put A Spell On You" and "Feelin' Good", might be quite different in some ways to his earlier work with Vaughan, but the same sense of drama is evident. 　　In his A&R capacity, Mooney helped to woo Xavier Cugat to Mercury, and he also produced several albums, including Dizzy Gillespie's Jambo Caribe (1964) and Vaughan's penultimate work for Mercury It's a Man's World (1967), for which Mooney also arranged some of the songs.
