The purpose of this study was to investigate the effect of using tape-recorded aural models for home practice on selected sight-reading and performance skills of sixth-grade clarinet students. The experimental design was a pretest-posttest control-group design with an additional posttest measure. It was predicted that students in the experimental group would do significantly better than students in the control group with regard to pitch reading, rhythm reading, tempo accuracy, and intonation accuracy as measured by the sight-reading and performance tests. It was also projected that students in the experimental group would complete more music exercises during the study than students in the control group. The statistical analysis indicated no significant difference between the experimental and control groups with regard to either the skills measured or the number of music exercises completed during the study. These results appear to indicate that tape-recorded aural models used in this study had no observed effect on the selected music skills.
