Hello Cello is the educative program of the Cello Biënnale. Hello Cello promotes classical music and the cello at elementary schools, among other places. The project De Bestorming is an important part of that. Right before the festival, elementary schools in Amsterdam are “stormed” by the eight cellists from Cello8ctet Amsterdam. For the whole school, the entire day revolves around the cello, and the children then attend a concert in the Muziekgebouw by the Cello8ctet, during the Biënnale. In 2016, among others, elementary school De Regenboog was stormed, which turns out to have had a huge effect.
