The purpose of this study was to investigate the attitudes, preferences, and practices of Arizona high school choral directors towards sight-singing skills, and student success in group sight-singing evaluations, the teaching of sight singing including preference for a specific sight-singing system, and the instructional practices employed in daily rehearsals. High school choral directors from the state of Arizona (N = 86) completed an online researcher-designed questionnaire that gathered demographic information as well as information regarding directors' attitudes towards sight-singing instruction, which exercises are used for sight-singing instruction, and directors' self-perceived ability not only to sight sing but also to teach sight singing. Independent variables such as teaching experience, level of education, the system they were trained to use as a student, the system they currently use in the classroom, their self-perceived ability to sight sing, their self-perceived ability to teach sight singing, their choir's sight-singing rating at festival, and their daily instructional practices (as measured by minutes per week of sight-singing instruction) were used to investigate potential differences in attitudinal responses. Multivariate analyses of variance were conducted to investigate potential differences in responses according to various independent variables. Significant differences were found in responses to statements of the importance of sight-singing instruction according to level of teaching experience and time spent on sight-singing instruction in the classroom. No significant differences were found for statements of directors' attitudes toward sight-singing instruction according to level of education or prior training. Results indicate that Arizona high school directors are a seasoned and highly education group of professionals who understand and believe strongly that sight-singing instruction should be a part of their choral music rehearsals. These directors use a variety of systems and resources to teach sight-singing and all dedicate time to sight-singing each week in their rehearsals. Despite the overwhelming support for teaching sight-singing in daily choral rehearsals, there is a lack of participation in choral adjudication festivals where group sight singing is assessed. Further research is suggested to investigate the lack of participation of Arizona high school choral teachers in the group sight-singing component of the state choral adjudication festivals.
