From September to November parents and grandparents helped 40 middle-class kindergarten children and 30 large group children made musical instruments from recyclable materials and material from nature: drums in metal or cartoons, balloons and yarns of elastic, trumpets from cartoon tubes, plastic glasses, coloured wire and buttons, shoe box guitars, elastic yarns and coloured paper, plastic boxes filled with rice, clipped between two plastic spoons.

Blessed and proud of what they did, they went out into the yard of the kindergarten and held a real concert to complete the musical collection.
