MARIE GRASS AMENTA On Treating Singers With Respect. “Many amateurs singers feel in order to ‘do the music justice’ you need to be treated poorly to be able to achieve true perfection. And when we allow directors to get away with behaving badly, they feel they CAN get away with it. A conductor has the power to attract singers or repel them.” It is important to remember that our behavior during rehearsal is not just about the music or the sound, but about people. How we correct is as important as what we correct.
