This research explored the impact of informal learning (IL) in primary music initial teacher training. A small group of undergraduate student teachers had an opportunity to learn about and facilitate an IL approach. Data were collected from interviews, participant reflective logs and researcher reflections. The findings show that perceived benefits included freedom for serendipity, pupil autonomy and aural learning; perceived tensions included student teacher anxiety and a lack of teacher control. The researchers propose two aspects for consideration: first, that language associated with IL has social meaning that must be updated; second, that while direct instruction remains at the heart of primary teacher education, IL can continue to be justified despite the current emphasis on direct explicit teaching.
