Harping about music's benefits

In some of Paraguay's impoverished communities which lack electricity, drinking water and cellular phones, music has come to supply a vital energy.

And the harp, an instrument of particular cultural significance in this South American country, has become a life-giving channel.

Some 600 girls and boys between the ages of nine and 18 in different communities were included in an ambitious project to study the harp called "Sounds of the Earth", directed by musicians Luis Szaran and Cesar Cataldo.
