Orff Schulwerk is defined by its practitioners as an approach to teaching music to children through the Orff media: speech, singing, movement, and playing instruments. The approach is often best known for use of the "Orff instruments," and some music educators criticize Orff-based instruction, claiming that singing is overlooked or deemphasized in the Schulwerk. The American Orff-Schulwerk Association (AOSA) approves teacher education courses in Orff Schulwerk, which are offered through universities, school districts, or local chapters of AOSA. In order to become certified in Orff Schulwerk, teachers must complete "levels" of these courses. One of the main criteria for approval by AOSA is that the instructors for the course have met certain standards, thereby being qualified for inclusion in the list of AOSA-approved teacher educators. The purpose of this study was to examine Orff Schulwerk teacher educators' beliefs about of singing. The research questions addressed (1) pedagogical and curricular priority beliefs; (2) self-concept beliefs; (3) efficacy beliefs, and (4) larger belief systems (Pajares, 1992). The study used qualitative inquiry in the form of open-ended interviews conducted with eight AOSA-approved Orff Schulwerk teacher educators from the United States. Line-by-line coding of the transcripts was employed to discern important words and phrases used in the interviews. The coded words were categorized to address the research questions. Quotes from the interviews were cited as evidentiary warrants to support the claims. The findings of the study indicate that singing, as one of the Orff Schulwerk media, is important to the approach; however, the ways in which singing is incorporated and prioritized in Orff Schulwerk varies according to the ability level of the students. Although several of the participants believed that they do not have good singing voices, they were able to overcome those feelings of inadequacy to arrive at a philosophical belief that everyone should participate in the act of singing. The participants' beliefs were greatly influenced by early experiences with family singing and by collegiate experiences with the Orff Schulwerk approach. Recommendations for Orff Schulwerk teacher education are proposed, along with suggestions for further study.
