Rise and sit down in unison with the others.
Do not look all over the place, but keep your eyes on the conductor.
Do not cover your face with your music.
Remember it is the conductor's duty to beat time. Keep head, arms and feet still.
Do not try to sing louder than the others. You will not be heard any better and will strain your voice.
Remember to hold the long note for its full count.
Time and rhythm are the two great factors in chorus singing.
Remember that "rests" are of as great importance as "notes" in music.
Do not start before or hang on after the others have ceased to sing.
Do not fail to slightly accentuate the first beat of each measure except where accents are especially marked on other beats.
