Teacher Nanonte Dailey teaches students at IS 364 in Brooklyn how to sign “Lift Every Voice and Sing.” The students are seated in chairs on either side of each other, forming an aisle. They are dressed in simple school uniforms--black shirts and dark blue or black pants. Dailey stands in the middle, at the top of the aisle. They sing and sign an up-tempo version of the song by a female vocalist. They sing and sign only the first verse.
