Held annually, this competition brings together several hundred musicians and singers in rounds across Brittany, culminating in a final in Pontivy. The competition features several categories. The Questembert competition, from 2:00 PM to 6:30 PM, is organized by the Andon association: a meeting place for people from the Upper Vannes region, the Gallo-speaking Vannes area, the Pays d'A-bas, Redon, and the Porhoët region. Andon also hosts a Fest-deiz (daytime Breton dance event) at 2:30 PM, running concurrently with the Kan ar Bobl 2026 competition. This year, the groups An Amaturien, Ayoul tad&mab, Grain de Celte, and the Andon singing workshop will provide entertainment at the Fest-deiz. A Breton singing workshop will also be held the day before with Elodie Jaffré and Maude Madec. Registration is by email.
