TRT World's John Brain reports.
The funeral will start with music from the Aretha Franklin Orchestra, but also includes performances by Faith Hill, Ariana Grande, the Clark Sisters, Chaka Khan, Ron Isley, Fantasia, Jennifer Hudson, and Stevie Wonder.
The service is for family and friends only, meaning that members of the public will have to watch online or on a giant screen reportedly being erected near the church.
The service is scheduled to begin at 10am local time, 3pm BST.
Hudson's performance is highly anticipated - producer Harvey Mason Jr. told the gossip site that Franklin was excited about the biopic a week before she died on August 16. "I think it's going to be a very jubilant experience".
Aretha Franklin is dressed in a sparkling full-length gold dress with sequined heels for her final outfit.
She was awarded America's highest civilian honour by George W Bush in 2005.
Instead, the couple have sent a letter which will be read out during the service. Thursday night, a concert in her honor was held in downtown Detroit.
'This is a real life that has been lived, that a person regardless of how famous she became no matter how many people she touched around the world'. "Death is a part of life".
How did Aretha Franklin die?
'I do not plan anything (with) someone I love like that, ' Robinson, a Motown great who grew up with Franklin, said.
Earlier in the week, mourners paid their respects during her public viewing at the Charles H. Wright Museum of African American History.
