black gospel choir arrangement

black gospel choir arrangement

I have a 3.5 minute black gospel 'call-and-response tune that I did on Logic pro. I want to upgrade it with a bigger more realistic choir.
It's in 4 part but 3 part seems more in fashion.

Do you do just your own voice on autotune or do you use more singers? If you do an arrangement can you provide the sheet music for the unique sections (not the repeated)?
