A woman and a toddler on May 21, or Soman, one of the 24 traditional solar terms based on the lunar calendar that signals the start of summer, watch a display at the World Music Fountain held at the Seoul Arts Center in the capital's Seocho-gu District. The hourlong display, which features the changing of colors and shapes to music from around the world, runs through Oct. 31: twice each weekday excluding Monday and five times daily on weekends.
