All 350 pupils at Windmill Primary School will be performing in this afternoon's concert at Leeds Town Hall. They're being taught how to play their instruments by professional musicians from Opera North.
Tim Crooks from Opera North has been teaching the children at Windmill Primary School how to play stringed instruments. He says he hopes the project will give them a lifelong love of music, as well as teaching them many useful social skills.
Primary school pupils are tuning up for their debut, alongside some of the best musicians in the country.
All 350 children at Windmill School in Leeds are taking part in the concert tomorrow at the city's Town Hall - and it's only 4 months since they started to learn how to play their instruments as Emily Kerr reports.
