The Pearwood Pipers, the recorder ensemble and madrigal group I used to sing with, let me guard their pavilion while they played a gig.
One of the props that they have is a large wooden chess set. I set that up in front of me. Then I pulled out a hidden bottle of soda, poured it into a ceramic goblet, and sipped it while I strummed my harp. Under the pavilion's shade, I felt like an errant squire in an Arthurian adventure.
I was surprised at how many folks came up to learn chess or about the harp. I played a game of Queen and Pawns with a five-year-old, and I taught a twenty-something the other pieces. What felt like a home-school family came up and spoke with me about the harp and its tuning.
Then the Pearwoods came back with some other musician friends and began a jam session.
