When Cal takes the children to the "black church," one of the differences that the children notice is that there are no song books. Scout asks how do people sing if they don't know the words. Cal tells her to just wait and see. Zeebo leads the people in song by "lining" which is a method where the song leader says the line first and then the people sing it after him. The children also notice that the church service is longer than at the white church. The black church members don't really welcome Scout and Jem and tell Cal to let them go to the "white church". Also the people at the black church are much poorer than the white members they are familiar with. The spirit of the church is also different and the way the black people worship is more intense.
