This is an orchestra masde up of primary school students - under twelve years old. The music was recorded in an open air concert beside an extremely busy main street. See the flyover in the background. Hardly optimum conditions but gives an idea what even very young musicians can do when they're motivated. The secret I think, is that music is just embedded into the kids' activities, as fun. The second clip shows an even younger orchestra. Some of the kids barely reach over their marimbas but they are having a good time expressing themselves.
