THE next Jimmy Barnes or Kylie Minogue is sitting in a classroom, in a school somewhere in the country, maybe in the Tweed.

Without programs like Music: Count Us In, those talents may never be found, they may not even pick up an instrument or sing a note without those programs.

Tweed Public School year 3 student Rory Sillar is one potential future star, but you won't see him on The Voice or Australian Idol, as Heavy Metal is his preferred genre, more specifically shredding guitar riffs.

"My dad played in a metal band, so yeah my favorite music is heavy metal for sure, I have been playing about a year and really love it," Rory said.

This year on October 31, over half a million Australian students will sing the same song at the same time to put an exclamation mark on the importance of music in kids' lives.

Rory's teacher Fiona Simpson has got her students practicing hard for this year's event.

"They have one music lesson a week for one hour, and by the time the day arrives, they will have the song perfected," Mrs Simpson said.

Front women of band George and solo artist Katie Noonan, has been mentoring four talented students in writing this year's song titled Keep On.

"I am a big believer in music in education, it was such an important part of my life while I was growing up so I am really excited to be involved in mentoring students as part of music," Miss Noonan said.

The program also helps teachers' professional development, giving them confidence to deliver music to their students.
