Phi Mu Alpha Sinfonia is a national men's music fraternity which, since its founding in 1898, has grown to be the largest music fraternity in the world. Members of Phi Mu Alpha, known as "Sinfonians," share a love of music that unites them as brothers with a common interest. The Fraternity teaches men to develop themselves and their art, not for the sake of art itself, but as a means of enriching the lives of others.
Phi MU Alpha Sinfonia’s collegiate chapters participate in a broad range of activities emphasizing brotherhood, service, and performance in music.
