Annamarie Harris, publicity officer for the Rotorua branch, said the performers included the winners and place-getters in LearnMusicNZ's Senior, Intermediate and Junior Scholarships for 2018.
"All of these students have earned the right to perform in the concert because of successes in competitions and examinations."
She said it was wonderful to have so many performers.
"This is an annual event and we seem to be growing in numbers every year."
John Paul College's Veronica Chen, 14, played the violin and piano.
She has played the violin for two years and the piano for six.
"I'm looking forward to listening to other people play and seeing all the talent that's in town."
She said what she liked about playing the violin and piano was expressing her feelings and enjoying the music.
She was looking forward to showing what she could do in the showcase.
Taupō's Teresa Painuthara, 12, and Marionne Montesa, 12, both played the piano and said they were looking forward to listening to the other performers.
Teresa said she enjoyed seeing how much she had progressed over the year and how she had achieved her goals.
Taupō pianist and violist Matt Montesa, 8, and pianist Stanley Su, 7, said they both enjoyed making people happy when they listened to their music.
Two guest artists also performed - pianist Shamus Baker performed Revolutionary Etude by Chopin and vocalist Maddy Thompson who sung O del mio dolce ardor by Gluck.
