The winners of this year's Côr Cymru - Choir of Wales - competition will be offered the opportunity to represent Wales at the Eurovision Choir of the Year 2017 competition.
S4C has secured broadcasting rights for the brand new competition, to be broadcast live on the channel on 22 July.
It's the first time that a choral Eurovision competition has ever been held and it will take place in Latvia this year.
The evening will be hosted by the highly-respected composer and conductor Eric Whitacre and the adjudicators will include world-famous choral composer and critic John Rutter and the highly esteemed soprano Elina Garanca.
The Welsh choir will be among some of Europe's most brilliant singing groups, with the best choirs from Austria, Belgium, Denmark, Estonia, Germany, Hungary, Slovenia and home country Latvia set to compete.
