Jerry Hey was born in 1950 in Dixon, Illinois, to a family of musicians. His mother was a pianist and his father was a trombonist; two older brothers played trombone and tuba. After completing high school, Hey attended the National Music Camp for two summers. While in college, Hey studied under Bill Adam at Indiana University.

Hey then relocated to Hawaii to become a member of the band Seawind.

In 1976, Hey moved to Los Angeles with Seawind, which then recorded two albums for CTI Records under the direction of Harvey Mason.

Gary Grant, who had already been in the city for a year when Hey arrived and was a well-known session player, invited Hey to join him on recording sessions, which helped to launch his career as a studio musician.

Soon after arriving in LA, Quincy Jones got in touch with Hey to ask him to play and arrange for Jones's album I Heard That!!. Following that session, Hey and his associates were invited to perform on every one of Quincy's recordings. Hey later worked as a musician and arranger with David Foster.

Hey is the uncle of American keyboardist, songwriter, producer, arranger and musical director Henry Hey.
