Teaching traditional music by ear and conducting ensembles became Jonas’ second nature after attending a lot of international Ethno music camps, and being trained at Ethnofonik and Ethnofonik All Stars. After taking masterclasses of Ritmo con Señas, and becoming a certified Soundpainter, he uses these sign languages to conduct ensembles and to make arrangements.

Jonas currently leads two ensembles at Muziekpublique in Brussels, the East-West ensemble and the Balfolk ensemble. He was artistic leader on Ethno Denmark, Ethno Flanders and will be leader on Ruuhnu ViiulilaagerEthno Estonia 2019 and the Stage voor Traditionele Volksmuziek.

Moreover, Jonas has a lot of experience of working with children, leading for several years a children’s choir in Brussels and giving Soundpainting workshops.
