Body's earliest works, such as choral pieces "Ave Maria Gratia Plena" (1965), "People Look East" (1965), and "Carol to St. Stephen" (1975) reflect Body's early training as a church musician. His travel to South-East Asia in the early 1970s, where he encountered local musical traditions, significantly re-formed his compositional language. Many of Body's works are scored for both Western and non-Western instruments such as gamelan, sheng, and gangsa. "Resonance Music" (1974), for electric guitar and 6 percussionists, features gamelan; its premiere by the New Zealand Broadcasting Corporation Symphony Orchestra made first use of the set of gamelan gifted to the orchestra in May 1974 by the Indonesian ambassador to New Zealand.
