Each year, the Harmony Primary School Senior Choir participates in the WA Government Schools' Make Music Festival, held at Burswood Theatre.  The festival consists of a series of concerts exhibiting choir and ensemble performances given by both Primary and High School public schools from across Western Australia. Since 2008, Harmony Primary has proudly hosted one of the concerts in the series. This event is an opportunity for Harmony Primary School students to demonstrate excellence in musical performance, and provides enriching experiences in choral singing, solo performance and public speaking.
