The Music Department at Killingly High School offers courses in the performing arts as well as in music theory and composition. Through participation in these courses, students learn how to read music more accurately and express themselves more effectively. Students learn how to offer insightful critiques of their own compositions and performances through an analysis of the elements of music. Most courses are open to talented and motivated students in grades nine through twelve. There are no specific course prerequisites for band or chorus, however, students enrolled in band should be competent on a band instrument, and for students enrolling in chorus, and previous experience is helpful. For students new to the district, an interview with the director for placement in the performing groups is suggested as part of the course registration process. In both performing groups, the primary goal is training the student to be a more sensitive and accomplished musician.
