The children attended the workshop ‘‘Pulling out all the stops'' on Saturday, as part of the Australia and New Zealand College of Organists Academy, which was held in Dunedin.
Academy director and St Paul's Cathedral organist George Chittenden said the workshop was about encouraging children to be interested in organ music.
Norma was one of the biggest organs in the country and as a town hall organ had ‘‘interesting and exciting effects'' that would not be found on a church organ.
‘‘It's a really impressive instrument and they wouldn't normally have a chance to play it.''
Kayla Smith, who goes to Fairfield school, said she was a ‘‘bit nervous'' when she tried playing the organ, but she enjoyed how loud it got.‘‘We play on a keyboard at home, so it's not that loud,'' she said.
She definitely wanted to play an organ again.
