We report a simultaneous dual fMRI study, using sparse temporal sampling, of pairs of musicians singing complex and simple folksongs. Each pair of duetters performed under three conditions: solo singing, singing in unison with a partner, and singing in unison with a computerized piano performance. Each pair of duetters performed all conditions twice, once in the 1.5 scanner and once in the 3T scanner. The results implicate a distributed set of brain areas involved in the online coordination of interactive entrainment of human duetters, and provide the basis for a wider use of simultaneous dual-scanning paradigms.
