The problem lies in the complex nature of the organization itself. Sinfonia means many different things to many different people, with none of the definitions more important than any other. To understand truly the complex character of Sinfonia, one must first understand each of its component properties.
Music is the common bond that forms the basis of our fraternity.
Phi Mu Alpha offers each man an opportunity for fellowship, performance, self-expression, growth, and increased aesthetic awareness in music and provides a creative atmosphere in which each brother can further develop his talents and perfect his craft. Sinfonia builds a framework for future professional bonds of musicianship. Sinfonia creates an atmosphere in which musicians grow and learn from one another the essential elements of their craft, and provides a basis of mutual support in music. Sinfonia offers the opportunity for each member to participate in alternate styles and modes of performance through music outside the classroom, and provides a means through which university and college students can bring music to the community. Music is Sinfonia's reason for existence and serves as the common ground, which relates all its members nationwide.
