Music producers are responsible for the overall production of commercially recorded music. They work closely with recording artists and audio recording engineers to ensure everything runs smoothly and according to plan during a recording session. They monitor and control the technical aspects of a session, such as microphone placement, tracks used, sound and effects, musician needs, and anything else that influences the quality of the recorded music, as well as see to other needs of the musicians and recording engineers. They review prospective new artists, maintain ties with contracted artists, and may negotiate contract and recording arrangements. They also work on the final mixing and editing of the recording.
