The focus in this study is the relationships between one tertiary music academy and four amateur orchestras. In this study the kinds of cooperation that exist, how students benefit from participating in amateur orchestras, and how cooperation can be further developed is identified. Four administrators from the academy and four conductors were interviewed. The study shows that the bases for cooperation are informal arrangements and personal contacts between individuals. What the interviewees considered as the main benefit for students was that participating in amateur orchestras provided opportunities for orchestral playing that were lacking within their formal education. Policy decisions were based on the interviewees ideas about students’ benefits, which could be social, musical and professional. The interviewees also respected the students’, and teachers’, autonomy in choosing their own musical and professional paths. Both the academy administrators and the amateur orchestra conductors value the cooperative relationships between academy and amateur orchestras.
