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.

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, Ethno Estonia 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.
