A Negro spiritual, also known as a spiritual or a folk hymn, is a type of religious song that emerged from the African American community in the United States during the era of slavery. These songs were often sung by enslaved African Americans as they worked in the fields, and they served as a way to express their faith and provide hope in the face of oppression and hardship. Negro spirituals typically have a call-and-response structure, in which a leader sings a line and the congregation responds with a repeated refrain or chorus. The lyrics often draw on biblical themes and imagery, and may incorporate elements of African music and culture. The melodies are usually simple and repetitive, with a strong emphasis on rhythm and harmony. Some of the most well-known Negro spirituals include "Swing Low, Sweet Chariot," "Go Down Moses," and "Wade in the Water." These songs have been passed down through generations and have become an important part of African American musical heritage. They continue to be performed and celebrated today as a testament to the strength, resilience, and faith of the African American community.
