Donna Summer -- Music City Memorial

Donna Summer's family has scheduled a memorial for the Disco Queen -- and TMZ has learned, it will take place next Wednesday in Nashville.

It is not a public memorial. The memorial will only be attended by close friends and family.

Donna and her family moved to Nashville in 1994 -- and sources tell TMZ, Donna's family chose the city specifically because it was her home and was always extremely close to her heart. Nashville's also a cultural epicenter in the music world, so it just makes sense.

TMZ broke the story ... Donna passed away today in Florida due to complications from lung cancer.

She was 63.
