In To Kill a Mockingbird what is lining who does it and why is it done?

Linin' is where one person sings and the whole congregation repeats what was said. In the novel, when Scout and Jem go to church with Calpurnia, Zeebo is singing and all the members repeat what he says. This is often done because many of the members are illiterate or because they don't have enough money to buy hymn books.

Scout discovers linin' is when one person sings a line of the hymn and the rest of the congregation repeats it. They do this because most of them can't read even if they could afford hymn books.

In To Kill a Mockingbird, when Calpurnia takes Jem and Scout with her to church at First Purchase, Scout discovers that linin' is when someone sings a line of a hymn and the congregation repeats it. This is used because almost all of the church members could not read.
