ALTERNATIVE CAROLING

If you’ve ever wanted to participate in a mass musical mobile, here’s your chance. A glorious and chilly ritual since 1992, with only the technology changing over the ensuing years, Unsilent Night is composer Phil Kline’s annual electronic tribute to the joy of caroling. Tote your boombox to the Washington Square Park arch, where you will be issued a cassette or CD (apps also available) containing one of the minimalist work’s four interlocking parts. Hit your start button on cue (warning: miss it and risk being chastised mid-parade by the composer himself) and proceed eastward en masse. A single musical movement in literal movement, Unsilent Night is a spectacle of tintinnabulation to delight participants and bystanders alike. It all ends with a few magically meditative minutes in Tompkins Square Park.
