There is more than two decades of research about the neurobiological underpinnings of human singing behavior. Singing engages both the vocal motor and sensory networks in highly complex and precise ways. The process of vocalization, beginning with the vocal tract and ending up with discussion about the brain network involved in singing and integration with sensory feedback. Vocal motor control in humans is both hierarchical and parallel based on observations of preserved and impaired skills in persons with brain damage. Music training modifies the basic brain networks used for vocalization.
