La Nouvelle Harmonie Bruxelloise d'Accordéons regularly organizes workshops, as a co-production with Muziekpublique. One Monday per month, you can learn to play in an ensemble with a varied repertoire, under the leadership of Piet Maris. Now and then there is a new piece on the shelve, but the repertoire of past sessions gets continuously refreshed as well. Anyone who has a basic knowledge of chromatic accordion is welcome. Info and registering via Muziekpublique.
