There are many parallels between the music and worship of the African American Pentecostalism of the author’s upbringing and that of Afro-Caribbean religious groups, including Trinidadian Spiritual Baptists, the Haitian Heavenly Army, and Jamaican Revival Zionists. This can partly be attributed to their shared West African roots. Many features of West African worship have survived among these two geographically separate groups, including a heavy use of rhythm and percussion instruments, a call and response vocal form, and a climax of spirit possession, when congregants reach a state of rhythmically induced ecstasy in which they feel fully possessed by the divine. Both groups have also independently adopted white Christian hymnody, in which they stay true to the text but often change the music in an improvisatory style.
