People from the school community and the wider community can become involved with the performing arts at Tatachilla. To perform the musicals people are invited from the community to perform and to become part of the chorus. From the musical that was performed in 2005 by Tatachilla, The Sound of Music, the ladies who were the chorus of Nuns' have formed a choir which meets and performs regularly. Following on from this Choir, a men's barbershop group was formed, which also meets and performs regularly. The college also hosts the McLaren Vale Community Christmas Carols each year, with the choirs from the college and other schools, a guest artist and invites musicians from adjoining areas to form an orchestra for the event.
