[1] Although an honorary fraternity, Mu Beta Psi views itself as primarily a music service group.

The national fraternity and several chapters run scholarship programs[2][3] and pride themselves on providing service to their music departments.

At the 1961 National Convention, Mu Beta Psi amended its constitution to allow membership to women.

The Mu Beta Psi Alumni Association was formally established in early 1970, providing college graduates with a chapter to continue participating in the fraternity's activities.

Theta chapter was established at Saint Augustine's College in 1973 and remained active for thirteen years.

In the mid-1980s, the fraternity created its Permanent Board of Trustees to ensure the organization's stability.

The first members of the Permanent Board included Wallace DesChamps, Charlie Emki, David Wilson, and Bryan Reamer.

Mu chapter was established in 1993 at the University of North Carolina at Chapel Hill and would remain active for nineteen years.

A year later, Mu Beta Psi crossed the Mississippi River for the first time with the establishment of Sigma chapter at Saint Louis University in 2009; although, it would quickly go inactive.

During the 2010s, Mu Beta Psi officially established a national scholarship that is open to college students at the locations where it maintains active chapters.
