ABSTRACT The Orpheus Male Chorus of Phoenix occupies and maintains an historical place in the musical and civic history of the City of Phoenix and the State of Arizona. Organized in November, 1929, the Orpheus Male Chorus of Phoenix (OMC) is the only performing arts organization in Phoenix that can claim eighty-one years of continuous performance. The chorus gained popularity locally, nationally, and internationally in its first five decades. The breadth of the chorus's recognition began to decline in the latter part of the 20th century, but the chorus still retains a loyal following of audience members. This study focuses on the first fifty years of the OMC, especially the period from 1946 to 1979, the years the chorus was under the direction of Ralph Hess. Through his leadership the group's popularity and recognition reached a peak, thanks largely to his emphasis on civic responsibility, ties to service organizations, and musical ability and showmanship. No scholarly publications exist regarding this organization. Several boxes of memorabilia housed in the Arizona Historical Society Museum in Tempe, Arizona, serve as the primary source of material for this study. Concert programs supply information about concert repertoire, advertising, and chorus history. Newspaper articles from local and international press offer reviews, announcements, and media perceptions of the chorus. Information illustrating the abundant civic engagement of the OMC appears in proclamations and awards from local, state, national, and international personalities. This objective information helps propel the story forward, as do the personal letters and stories contained within the collection. Because many documents from the latter part of the 1970s are missing, the primary source information becomes more anecdotal and subjective. This study illustrates some of the ways in which the OMC went beyond mere survival to occupy a significant place in the musical life of Phoenix. Engagement in civic and social functions and support for non-profit organizations established the chorus as more than just a musical ensemble. Their pursuit under Hess of "Cultural Citizenship" earned them international recognition as civic leaders and ambassadors of goodwill.
