Sunday, Dec. 21: Filling December nights with music and song is a tradition that New York composer Phil Kline updated 22 years ago with his boombox parade, Unsilent Night, which is now a worldwide event. The NYC edition already came and went, but you can still take part in an orchestrated performance this Sunday. Taking a cue from Kline, Make Music New York has turned the winter solstice into a day dedicated to musical parades throughout the city, like Flat Foot Flatbush, where bluegrass musicians and flat foot dancers will tap from the Brooklyn Public Library to Barclays starting at 2:30pm. (If you want to join in, but haven’t flat footed before, there’s a lesson at 1). A thumb piano promenade, the Kalimbascope, starts at 5:30pm in McCarren Park (bells and chimes are welcome, too), and there are many more sonic events around the city, like a soundwalk on the High Line.
