Music ensembles involve complex social interactions between players in which coordination of actions and monitoring of outcomes are crucial in achieving joint goals. Previous event-related potential (ERP) studies of joint-action tasks have shown that the feedback-related negativity (FRN) is elicited when the outcome of one’s own actions, as well as another’s actions (oFRN), is different from what is expected. The present study aims to examine if the FRN and oFRN differ depending on the strength of the joint goal in a piano duet task. In particular, we hypothesize that even if the duet players do not produce sound simultaneously, alternating playing would still promote forming a joint goal, thus resulting in feedback processing of the outcomes from both player's parts. Ten pianists were paired to form five pairs and played short musical pieces during dual-EEG recording face-to-face. No notes were played together, and a note in either player's part was occasionally altered in pitch. Additionally, each pianist played the materials with a computer partner. The FRN was consistently larger than the oFRN, in line with prior studies. The oFRN was also larger when playing with a real human rather than a computer partner. We suggest that FRN/oFRN reflects online monitoring of action outcomes in a musical turn-taking task, which creates a dynamic social context in realtime.
