Smithsonian magazine announced today that Saturday, September 21, 2019 has been designated the 15th annual Museum Day during which participating museums across the United States open their doors for free to those who download a branded ticket. The annual event allows museums, zoos and cultural centers from all 50 states to emulate the spirit of the Smithsonian Institution’s Washington, D.C.-based facilities, which offer free admission every day.

This year, Museum Day will celebrate the Smithsonian Year of Music, an institution-wide initiative celebrating the Smithsonian’s vast musical collections and resources through 365 days of music-related programming. Music is not only a reflection of human creativity and innovation, but also a key method of communication and cross-cultural exchange and understanding. The Smithsonian Year of Music crosses disciplines, bringing together music-related resources in art, history, culture, science and education.
