Despite historic and ongoing support for the inclusion of improvisation in the elementary general music curriculum, music educators consistently report challenges with implementation of improvisational activities in their classes. This study was designed to examine (a) the extent to which improvisational activities were occurring in the participants' elementary general music classrooms, (b) the nature of these improvisational activities, and (c) participants' perceptions of the quality of their students' improvisations. The most common improvisational activities reported by these teachers were question-and-answer singing, improvising on unpitched and pitched percussion instruments, and improvising rhythmic patterns using instruments. Analysis of their reflections on these activities revealed three broad themes: (a) process, practice, and experience, (b) sequencing, scaffolding, and modeling in instruction; and (c) collaboration, reflection, and creation. These teachers stated they were most interested in the quality of the improvisational process rather than with the product and indicated that sequencing was crucial in the instruction of improvisation. While some put less importance and priority on improvisation, the majority perceived it as necessary to the development of students' musical skills, as an important way for students to show musical understanding, and as an empowering creative process that produces independent thinkers and musicians.
