After years of spontaneous musical merriment on June 21, the spirit of Make Music Day has come to visit on December 21, the winter solstice. For Make Music Winter, music can pop up anywhere. Rounding the corner, you may see a herd of electric guitarists, a choir of medieval singers, or a percussive Puerto Rican parranda coming down the street. Ingenious musical parades for iPhones, hand bells, bicycles, trombones, and boomboxes have delighted audiences since New York City began celebrating Make Music Winter in 2011. Last year, 37 cities joined the party. The seventh nationwide Make Music Winter celebration will take place on December 21, 2025: all free, joyful, and profoundly participatory.
