The CYO is the top-ranked orchestra of the Christchurch School of Music, comprising our best musicians between the ages of 16 and 25. It is mentored by Brian Buggy.

The standard of the CYO has been reflected over the years in dozens of favourable press reviews and many alumni having gone on to pursue international careers in music. CYO members past or present can be found in the Christchurch Symphony Orchestra, the New Zealand Symphony Orchestra and other elite groups.

The CYO maintains a high profile in the Christchurch concert music scene, performing concerts in such iconic venues as the Christchurch Cathedral and acting as host for visiting ensembles from overseas. It also goes on tour most years, with recent destinations as being as diverse as Sydney and Stewart Island.

Thanks to a grant from the Farina Thompson Trust, there is a discount of $100 to all Univeristy of Canterbury students who play in CYO.
