Often we hear that music with young children should be fun. And of course fun is important but fun is not enough. Fun is not educational (Dewey). Moreover, what is fun? In order to provide fun it is important to know what fun is in early childhood music education. Recently there was a mother who wondered out loud. We had a small discussion and one outcome was that the furthering of active participation – and confirmation of participation, responding to the children’s musical actions – is important. From this follows that the conditions should be created for active participation. Musical activities tailored to the possibilities of the children should be offered. When they can participate in something they understand: than there is a good chance they will have fun!
