Choral Director – Dr. Kathleen Orr

Chorus class fulfills the current course requirement for fine arts.  It is meant to be a continuous course of study culminating in Honors Chorus at the senior level.  Students in chorus class learn basic skills in proper singing technique, note reading, and sound production.  Students also perform a variety of music, with an emphasis on multi-cultural and world music.  All chorus classes are performance based, requiring participation in all school, county and state choral activities as determined by the director.  After school rehearsals are required in preparation for these adjudicated events.  Additionally, chorus class performs in both the winter and spring choral concerts.
