Adult music learners may expect to be more independent and therefore more inclined to engage in self-directed learning than younger learners; however, adults may not feel encouraged or supported to self-direct. In this qualitative study, the relationships between six adult instrumentalists and their teachers were examined using Grow's Staged Self-Directed Learning (SSDL) Model to determine if there was congruence or a mismatch between individual student learning needs and their teachers' strategies. Teachers reported a willingness to accommodate the self-direction needs of their students. Even in cases of teacher-student mismatch, more direction from the teacher was welcomed when they encountered technical difficulty or an unfamiliar style. Students who reported that they had little experience playing were more inclined to have low to moderate levels of self-direction, whereas more advanced players reported intermediate to high levels of self-direction. Cultural expectations were found to play an important role in determining if students desire to be self-directed learners. The quality of the teacher-student relationship and communication were both found to be an important determinant of successful collaboration. These findings suggest that the theoretical application of the SSDL model could provide teachers a means to assess and discern their adult students' learning needs.
