Straight from our website:
"In early spring of 1903, Mrs. Fredreka Howland, wife of William Howland, head of the Vocal Department of the University School of Music, Ann Arbor, Michigan, suggested that a musical sorority be organized which would aim for high standards of musicianship and for promotion of the highest type of music. She felt there was a need for such an organization. A meeting was held in Mr. Howland's studio to discuss this idea. There was some talk of a musical club but finally a Sorority was decided upon as better fitting plans for close bonds of friendship. It was decided that only students of fine character and special musical talent combined with excellent scholarship would be eligible for membership. On June 12, 1903, Sigma Alpha Iota Musical Sorority was founded. Following are the names of the founders, who were graduate students and faculty members: Elizabeth A. Campbell, Frances Caspari, Minnie M. Davis (Sherrill), Leila H. Farlin (Laughlin), Nora Crane Hunt, Georgina Potts and Mary Storrs (Andersen).
So, in short, what makes us different than other groups is that we're all bonded by one common love: music.
