SingFest is a choral event aimed at youth and community/chamber choirs, i.e. late teens/non-school youth choirs, through to the older age ranges. A well-known conductor is invited to be the commentator (providing written critique for choirs) at the festival. Each choir performs a programme lasting up to 15 minutes and then joins in for a massed item, usually also conducted by the commentator. In addition, one of the top choirs from The Big Sing may be invited to be a guest choir. However, regions are given flexibility to use different formats to suit their particular needs.
