Mu Phi Epsilon is an International Professional Music Fraternity whose purposes are the recognition of scholarship and musicianship and the promotion of friendship. Its aims are the advancement of music throughout the world, the promotion of musicianship and scholarship, loyalty to the Alma Mater, and the development of a true bond of friendship. 
Mu Phi Epsilon was founded at the Metropolitan College of Music in Cincinnati, Ohio, on November 13, 1903, by Professor Winthrop S. Sterling, Dean of the college, and Elizabeth Mathias a member of the faculty. Professor Sterling had in mind an organization for women comparable in aim to Phi Mu Alpha Sinfonia Music Fraternity for men. First he considered associate membership in Phi Mu Alpha, but decided to establish an organization for women only, to advance the cause of music in America and at the same time develop fine young women bound together in friendship through their common interest in the art of music.
