Emotional competence is the capacity to handle emotional situations effectively. A teacher's emotional competence influences the choices they make both pedagogically and during student interaction. This qualitative multiple case study examines the lived experiences of four elementary general music teachers for the purposes of exploring emotional competence as related to perceptions and practices in the classroom. Research questions included: Is it possible to observe a music teacher's emotional competence in action? If it can be observed, what is the relationship between emotional competence and teaching practices, including a teacher's decisions about music, interactions with children, and his or her own emotional self-management? What is the relationship between a music teacher's self-perceived emotional competence and observed emotional competence in teaching practices? Four elementary general music teachers were observed four times within typical music teaching situations at their respective schools, and three interviews were conducted with each teacher. Teachers completed three self-report inventories drawn from the literature and revised by the researcher. An administrator and three students for each teacher were interviewed as secondary participants. Data were coded for emotional intelligence branches as outlined by Perry (2004), emotional competence skills as outlined by Saarni (1999), and "adaptive coping styles" described by Gottman (1997), and presented as individual cases. A cross-case analysis was conducted. Findings suggest that elementary general music classrooms are emotional places. Music provides students with unique emotional experiences. Effective teaching within this context has an emotional ebb and flow in which music plays a vital role. Interactions between teacher and students may result in a feedback loop in which exchanges of emotional reactions occur and where teachers may be called upon to manage their own emotional responses. When adverse situations arise, a music teacher may choose an adaptive coping style suitable for the circumstance. These choices are influenced by their knowledge, skills, and emotional competencies. Teachers' perceptions of their emotional teaching practices are not always congruent with their observed emotional teaching practices. When the knowledge and emotional abilities of music teachers are used effectively, they can have a positive influence on the emotional climate of the classroom, which may, in turn, impact learning.
