How are audiences affected by live choral music concerts? What can we conclude about the experiences they have? How do their experiences differ? Can we identify drivers of impact? In 2013, Chorus America initiated discussions with WolfBrown to design a study to answer these questions and build a foundational understanding of the impact of attendance at choral concerts. A total of 23 choruses across North America participated in the study, including a cross section of youth and adult ensembles. Over the 2014-15 and 2015-16 seasons, 14,236 audience members at 136 different concert programs completed surveys about their experience. The study, published on June 2016, builds on a substantial body of past research conducted by WolfBrown and other researchers investigating the intrinsic impact of live arts programs.
