"Global Voices in Song" is a CD-ROM series that provides singers or listeners in classrooms and choirs with the materials needed for effective oral transmission of choral music from sources outside the European art music tradition. It was developed by Dr. Mary Goetze, Professor of Music at Indiana University (IU) and Dr. Jay Fern from IU Academic and Faculty Services. To date, over 20 songs have been collected, representing such diverse cultures as Swazi, Hungarian, Maori, Japanese, and Sotho songs. While prototypes exist for all of these cultures, volumes for the Swazi and Hungarian have been published. For each culture represented, two kinds of materials are included in the CD-ROM: (1) The music, which includes a model performance, the pronounced text, the written text and the translation, along with close up models for learning the movement, dance or game; and (2) The culture, which includes information about the context of the music, such as the history of the music, the location of the collection and the performers' lives. This article describes the development and evaluation of this instructional CD-ROM. (Contains 4 figures and 3 resources.)
