MERRIWA Primary School students will add their voices to a chorus of 4000 children as part of One Big Voice tomorrow.
The 50 students from Years 3 to 6 will help pack Perth Arena on Friday night to sing in harmony.
Music teacher Rose Longmuir said they had been practising their parts to 11 songs since term one and were “loving it”.
“It’s non-competitive and the kids work together with a whole network of students from all different schools, from all over Perth, all working together as one,” she said.
“They also get to perform in a non-threatening setting.
“They’ve got that environment to shine.”
The school has been involved since the event was established as Westcoast Songfest in 2001 and has grown from six to 80 participating schools.
