The four interactive outdoor instruments of Harmony Park along Naperville’s Riverwalk reflect the four-way test of the Rotary that questions if something tells the truth, is fair to all, benefits everyone, and builds goodwill. Past President of the Rotary Club of Naperville, John Norman, said, “This is a gift to the city to create harmony right in our own backyard. Music is a universal language and bridges the age gap, physicality and creates a sense of community and belonging.”
