With the perspective that “we are witnessing a dynamic shift in [cultural] participation, both in amount and in form,” this series of case studies was prepared by the Wallace Foundation to help arts organizations attract and engage new audiences, in order to help secure their artistic and financial sustainability. The case studies examine efforts to increase participation in four American arts organizations, including a choir, a theatre company, an opera company and a museum. The reports delve into turning single-ticket purchasers into repeat attendees, generating interest and participation among young adults, creating opportunities for families to attend the opera, and countering stereotypes concerning classical music audiences.
