The purpose of this study was to identify the characteristics of common elementary music class activities that elicit situational interest, the short-term interest that emerges spontaneously in learners when faced with environmental factors in an educational experience. An instrumental case study approach was employed, with 24 fourth-grade children serving as participants, at a school in which the researcher was the music teacher. Over a 4-month period of engagement, data were gathered through small-group interviews, writing experiences, one-item surveys, videotaped observations of class periods, and examination of material culture. Analysis based on open and focused coding processes revealed that lessons containing elements of novelty, kinesthetic activity, self-efficacy, challenge, and creativity led to increased situational interest. Incorporating these themes into music classroom activities may be a way to enhance children's interest in the experiences, leading to more increased engagement and improved performance outcomes.
