Although relatively few studies exist, a review of the research reveals some common characteristics of an effective music teacher. Effective music teachers tend to be extroverted, enthusiastic, and care sincerely for their students. Such teachers are competent in musicianship (particularly in diagnosing and correcting musical errors and in using voice in demonstrating performance technique), in classroom and rehearsal management, and in the ability to relate lesson objectives to student interests and needs. Frequent eye contact, use of physical gestures, and variation of facial expressions and speaking voice are characteristics of many effective directors. (IS)
