Three Rivers Voices is a one-day regional choral event bringing together school-aged singers from Macquarie Conservatorium, Mitchell Conservatorium, Orange Regional Conservatorium and Young Regional Conservatorium for a massed choral experience led by specialist conductors, accompanists, and supporting staff.

The project aims to strengthen regional choral pathways, foster collaboration between conservatoriums and schools, provide high-quality ensemble experiences for young singers, and celebrate collective music-making in a regional context. Two choirs will be open to all participants of that age group in a massed choir setting, and one choir will be smaller and auditioned for more advanced participants.
