A style of community dance popular in New England since Colonial times, contras start out as two lines of partners facing each other and then the next couple on each side. There’s a live band and callers, and we walk through the sequence of steps before the music begins. The whole point is to have fun, and you wind up dancing with everyone in the line before the piece is finished. This example is from theĀ Lamprey River Band’s dance series in Dover’s city hall before the monthly event moved to a Unitarian-Universalist church in neighboring Durham. This particular dance is named Petronella.
