The rising sound of vibrating clarinets, booming tubas, high-pitched flutes and echoing cymbals can be heard through the halls of East Hall High School. The more than 60 students who comprise the school’s wind symphony are practicing this week and next for two prestigious upcoming performances. The symphony will perform Jan. 30 at the Georgia Music Educators Association’s annual conference in Savannah and Feb. 7 at the Alabama Band Symposium at the University of Alabama in Tuscaloosa.
