Research has shown that an audience can make a great difference to a musical performance but limited research has explored this with primary school-aged children. Using an action research study, participants from a primary school choir, students in fifth and sixth class formed into a choir through a compulsory singing programme, were surveyed to discover their experiences of performing for an audience. The study was completed during a busy period in the school calendar when participants competed in an eisteddfod and performed at the annual school Open Day concert. The events occurred three days apart and featured a performance of two pieces by the choir, the same repertoire being performed for both audiences. The eisteddfod audience included an adjudicator, eight competing choirs and their conductors, with family and friends from each choir also in attendance. The audience for the second performance, Open Day, was made up mostly of family, friends and other school students. This audience could be considered a known audience. Given the two different audiences, the opportunity to discover how the children felt was discovered through a survey prior to and after the events. Surprisingly, participants were more concerned about performing for a known audience, with 25% acknowledging this as difficult with only 9% indicating Music Performance Anxiety (MPA) about performing for an unknown audience. Further exploration suggested the audience expectations of repertoire and performance technique further influenced the choristers experience of MPA. Following this experience, data was collected prior to the annual Speech Night presentation, again for a known audience with repertoire expectations. Implications for conductors include understanding the sign and symptoms of MPA in students in their care, repertoire selection, preparing students for performances and assisting young singers to present to an audience rather than worry about the expectations of the audience.
