what two instruments only did the white people use in their church services?

In many historical contexts, particularly in the 19th and early 20th centuries, white congregations in certain Christian denominations primarily used the organ and the piano as the two main instruments in their church services. The organ was often favored for its rich sound and ability to accompany hymns, while the piano provided versatility and a more intimate setting for worship. These instruments played a significant role in shaping the musical tradition of white church services during that time.
