THe Alpha Mu chapter of Tau Beta Sigma was established at Wichita State University on May 4, 1952. Since then the sisters of Alpha Mu have devoted their time and efforts to serving the Wichita State University Bands, Wichita community, and promoting the advancement of women in music.
In 2002, the Alpha Mu chapter marked its 50th anniversary. The celebration included the commissioning of a piece composed by Dr. Katherine Murdock, an esteemed member of the WSU music faculty. The WSU Symphonic Wind Ensemble performed the piece at their concert in May of that year.
