ranging from childlike simplicity, embellished Eastern pentatonicism, medieval Western modality, fragments of plainchant, occasional outbursts of expressionistic angst, complex textures which include the development of motives and Western counterpoint, Eastern heterophony, and a deep spiritual dimension with both Eastern and Western overtones. There are allusions to indigenous music but not direct quotations: where the didjeridu occurs its function has always been discussed between composer and performer. To these he has often added theatre and ritual, costume, lighting and dance, most manifest in such orchestral works as Bird Spirit Dreaming (2002), Full Moon Dances (2012) and Frog and Star Cycle (2015). Cultural symbols such as the Virgin Mary and her Eastern equivalent, Guanyin, goddess of compassion, make frequent appearance in the guise of the Earth Mother, protector and nurturer of the environment – Edwards' work has always had a strongly ecological focus. Behind the vivid surface activity however, the mysterious Australian bush is always present as a constant backdrop, providing unity and coherence. In the 1970s, Edwards' attunement to the sounds of nature in a mindful, meditative way had a powerful effect on his music. He came to regard the sacred pieces as sonic contemplation objects similar to the honkyoku repertoire of the Japanese shakuhachi. Years later he re-established contact with Dr Graham Williams, a friend from student days, who had given up his career as a pianist to train as a meditation teacher in the Burmese and Tibetan traditions. Williams who, as director of the Lifeflow Meditation Centre in Adelaide and was developing a uniquely Australian form of meditation, perceived that all of Edwards' music possessed a quality that naturally induced a meditative state.
