Sonc Festival is an international chamber music festival in Slovenia, founded in 2016 by violinist Tanja Sonc.

“I founded the festival with a great desire to create chamber music at a high level in my home environment.”

“I want to show the beauty of Slovenia to musicians from abroad, to present our culture and cuisine, and to introduce classical music to the local audience. I have learned a lot during my studies at home and abroad, so I want to share this knowledge and bring something valuable back to my society. I believe that I can bring a lot of positive energy, motivation for young people and enliven summer evenings with the Sonc Festival concerts. Music connects people and we need it more than ever nowadays, because it is a universal language all over the world, understood by everyone.”
