Last night's performance by pupils from throughout the region was the 39th and featured a combined choir of 180 and orchestra of 180, with some pupils taking part in both.
Co-ordinator Sara Brown said school music departments were very passionate about the event.
Some of the teachers involved had taken part as pupils.
For some of the smaller, rural school pupils it was a rare opportunity to perform in such a big venue and with so many others, she said.
For others it was a chance to show off the skills they had developed through hours of music practice.
"There is an amazing feel to this, as pupils get to play or sing with others.
"There is just a big buzz," she said.
The event showed the diversity of music available for Otago's young people, with performances by the region's chamber music winners, Trio Boulanger, and Smokefree Rockquest winners T.F.F.
