Musical composition is widely considered to be a fundamental component of good musicianship. Recent state and national standards make it clear that preservice music teachers will be expected to include the teaching of musical composition in their curricula when they enter the field. The purpose of this study was to investigate the integration of musical composition into secondary instrument techniques courses. Twelve (N = 12) music education majors in two secondary brass techniques courses composed music for beginning brass ensemble, using an assignment designed by music education faculty in collaboration with a music composition faculty member. This study supports five suggestions for practice in secondary instrumental techniques classes, namely that musical composition: (a) can be a valuable component of a secondary instrument techniques courses, (b) served as an effective final assessment, (c) provided insight into beginning instrumentalists' perspectives and practicalities, (d) developed pedagogical knowledge, and (e) was a meaningful creative project. The students suggested that more specific parameters were needed, that composing multiple duos and trios might be more effective than composing one large piece, and that it was important for the compositions to be performed, although endurance could be an issue.
