23 years after the Spirit of Sinfonia has made a presence in Radford University as Phi Mu Alpha Sinfonia's Xi Theta chapter, the brotherhood of Sinfonia is just as strong as it was on October 6, 1898 under the direction of Ossian Everett Mills.

The Xi Theta Chapter continues to achieve our mission by advancing music in America. When one walks around Radford University's beautiful campus, there is a good likelihood that they might here music being played or sung by one of our brothers. We frequently hold Mills Music Missions to local hospitals as well as many other musical opportunities such as singing the national anthem at a Radford University Basketball game.
