solving can be accomplished through musical performances and projects like composing (Elliott, 1995, p. 72). Elliott suggests that performance of a musical work is especially valuable in assessing musical achievement because it provides authentic and tangible evidence of a person's moment-to-moment musical understanding (Elliott, 1995, p. 76). Theoretical Rationale Guiding students through a structured composition activity with clear limitations may help insure success in the composition process. Brophy (1996, p. 17) concludes that "guided composition is an excellent technique for building confidence in students' creative and notational skills". Guided composition involves the instructor controlling as many parameters of the composition as necessary for the developmental level of the student composers. Brophy (1996, p. 15) states that "a beginning composer who is not yet familiar with music notation needs to become personally involved in writing music within a context that is creative, comfortable, and developmentally appropriate in order to build his or her understanding of musical signs and symbols." The guided composition process is systematic. First, the educator sets the necessary parameters for successful composing and notation by the students. Depending on the developmental level of the students, these parameters may include rhythm, length, scale, clef, and ending pitches. Next, the students learn the prescribed aspects of the composition, and practice notating these elements individually. After gaining an understanding of these elements, students improvise a melody on an instrument set up with the pitches determined by the educator. When students have developed a melody they prefer, they notate that melody in a first draft. Once students have finalized the composition, they are asked to create a final copy using the
