We investigated whether people monitor the outcomes of their own and their partners %26apos;individual actions as well as the outcome of their combined actions when performing joint actions together. Pairs of pianists memorized both parts of a piano duet. Each pianist then performed one part while their partner performed the other; EEG was recorded from both. Auditory outcomes (pitches) associated with keystrokes produced by the pianists were occasionally altered in a way that either did or did not affect the joint auditory outcome (i.e., the harmony of a chord produced by the two pianists %26apos;combined pitches). Altered auditory outcomes elicited a feedback-related negativity whether they occurred in the pianist%26apos;s own part or the partner%26apos;s part, and whether they affected individual or joint action outcomes. Altered auditory outcomes also elicited a P300 whose amplitude was larger when the alteration affected the joint outcome compared with individual outcomes and when the alteration affected the pianist%26apos;s own part compared with the partner%26apos;s part. Thus, musicians engaged in joint actions monitor their own and their partner%26apos;s actions as well as their combined action outcomes, while at the same time maintaining a distinction between their own and others%26apos; actions and between individual and joint outcomes.
