Which countries are participating?
Choirs from 9 EBU Member countries (Austria, Belgium, Denmark, Estonia, Hungary Latvia, Germany, Slovenia and Wales) will compete for the title of Eurovision Choir of the Year, with prizes including a recording deal for the winning choir.
Each choir will perform a six minute unaccompanied set in any genre and will be judged by a high-profile jury including British composer John Rutter and Latvian mezzo-soprano Elīna Garanča.
"Singing in choirs is a healthy, social and artistic activity that anyone, young or old, musically experienced or not, can take part in - and one which is growing in popularity across the world," said EBU Head of Live Events Jon Ola Sand. "Eurovision Choir of the Year will showcase the vast possibilities of the human voice and aims to inspire new singers to get involved," he added.
