Usually the experience given from the groups are conversion and salvation. Jubilee quartets are a-cappella ensemble. The first to discover “jubilee” were the Fisk Jubilee Singers. To help avert the school from closing,  the white Northern missionary music director, dedicated to music and proving African-Americans were intellectual equals of whites, went on a tour to earn money for the university. The group traveled to over 10 states. From then on, students at other HBCU’s like, Hampton, Tuskegee, and Wilberforce, followed. The quartets were of close harmonies, formal arrangements, and a style of musical expression and technique discovered from Western musical traditions. Examples of Jubilee quartets are Golden Gate Quartet, Dixie Hummingbirds, Original Five Blind Boys of Alabama, and more. In time, the form of quartets spread from universities to black churches. The Golden Gate Quartet performed spirituals with rhythmic beat of blues, jazz, and gospel standards.  This new style evolved jubilee singing by the 1950s. [embedyt] https://www.youtube.com/watch?v=2vTdZpeAWR8[/embedyt]
