The purpose of the study was to provide insight into the musical responsiveness of different groups ofparticipants. A listening activity was developed to measure likeability of preselected excerpts in different performance media. One-hundred-and-sixty-three subjects, students from Grades 2, 5, 8, 11/12, and trainable mentally handicapped (TMH) students, participated in the study. Students listened to excerpts from Puccini's La Boheme, Haydn's Symphony No. 104, Mozart's Vesperae Solennes, and Hoist's First Suite in E-flat, while simultaneously manipulating a Continuous Response Digital Interface (CRDI) dial. Overlays used with the CRDI dial were developed specifically for the populations tested and included a pictographic scale continuum. Results indicated that (a) second-grade participants rated all excerpts higher than did the other groups, and (b) instrumental music examples were rated higher than vocal music examples. Results concur with findings reported in music preference research literature.Few will dispute the claim that it is the responsibility of music educators to broaden their students' musical taste to include music of a wide variety of forms and styles. Hargreaves (1982) stated that educators often fail to take into account the fact that attitudes can be influenced and that experience with art music can help students develop a more positive attitude toward it.Empirically based investigations measuring perceived aesthetic response to music stimuli are growing in popularity. In a study on perceived aesthetic experience (Madsen, Brittin, & Capperella-Sheldon, 1993), 30 faculty members and advanced graduate students listened to a 20-minute excerpt from Act I of Puccini's La Boheme and simultaneously manipulated the dial of a Continuous Response Digital Interface
