SummaryDuet singing is a form of social interaction between two individuals which requires the precise interindividual coordination of vocal emissions. How the brain controls this cooperative behavior was so far unknown. Here, the individual vocalizations and the underlying brain activity in free-living pairs of duetting songbirds has been recorded in parallel with novel miniature transmitters. The data revealed that preprogrammed temporal duet patterns in each songbird’s brain were altered by the partner’s vocalizations to enable optimal interindividual coordination during joint singing.
