Gospel music is a genre that emerged in the early 20th century among African-American communities in the southern United States. It is deeply rooted in the rich traditions of the African-American church and is characterized by its dominant vocals, often featuring complex harmonies. This genre has had a profound influence on many forms of popular music, from soul to rock-n-roll, and has produced iconic figures like Mahalia Jackson and the Staple Singers. Notable works within the genre include "Take My Hand, Precious Lord" and "Oh Happy Day".
