The purpose of this study was to investigate the effects of projected film visuals on singers' expressivity in choral performance. The study was divided into three phases. In Phase One, university choir singers (N = 21) viewed eight audiovisual pairings (two film excerpts and four choral etudes) and rated these pairings according to perceived music to film congruency. Based on these ratings, two choral etudes were identified that elicited the broadest congruency contrasts when paired with the film segments.In Phase Two, a different group of university choir singers (N = 116) rehearsed and prepared both of the selected choral etudes referred to as "Doh" and "Noo." Subsequently, these singers were organized into smaller chamber ensembles (n = 11), and performed each choral etude three times under the following conditions: (1) while viewing congruent film, (2) while viewing incongruent film, and (3) with no film projected. After each performance, singers reported their level of self-expression. At the completion of all three performances, singers reported their preferred performance condition. Finally, participants listened to their audio-recorded performances and rated these for performance expressivity and personal preference. During Phase Three, choral experts (N = 8) rated performance expressivity and reported personal preference for each audio-recorded performance. iv A two-way ANOVA with repeated measures found significant main effects of both etude and film visual performance condition on participants' expressivity ratings (p < .001).
