Its status once again changed in 1962 to that of an international music sorority, following the installation of the Alpha Tau chapter at the Philippine Women's University in Manila.

In its own words, the fraternity aims for the advancement of music throughout the world and promotes scholarship, musicianship, and friendship, along with encouraging each member's loyalty to their Alma Mater.

To celebrate the 75th Anniversary of Mu Phi Epsilon, the Fraternity and the Foundation cooperated in building and endowing a cottage/studio for a composer-in-residence at the Brevard Music Center in North Carolina.

She accepted but later found it necessary to decline the appointment, so Elie Siegmeister was named as the composer to occupy the Chair of Composition at Brevard Music Center.

Notable composers to follow include W. Francis McBeth, Elliot DelBorgo, Walter Hartley, Fisher Tull, Don Freund, and New York others.

Once through this process, candidates gain full membership in Mu Phi Epsilon as long as they remain in good standing academically and professionally.

The administration of Mu Phi Epsilon is made up of three main bodies: The executive board, the Foundation, and the district directors.

The Mu Phi Epsilon Foundation was established for the benefit of philanthropic projects suitable to commemorate the aims and purposes of the Fraternity.
