Grace

I recall a festival at Harper's Ferry.

An elderly man played a hand made hammered dulcimer. His hands blurred when he moved from string to string.

Ten African-American women from the coast of Georgia sang spirituals. And the ring of listeners began to clap to the rhythm of their music. 

Amazing Grace sung a cappella. With the last notes still ascending ,amens were heard as we raised our hands in prayer and awe.
