The talent of the Black folk preacher can be evaluated according to how he renders the metrical lines while still delivering the message. Although Rev. Jemison preaches in the traditional chanted sermon style, he seldom gets emotional feedback from his congregation. Music is of great importance throughout Black-American religion. At Mount Zion, however, it tends to be very rigid. The choir sings anthems, hymns, and arranged or concertized versions of the spirituals, interspersed with an occasional gospel song.
Musical accompaniment is by organ and piano only.
Occasionally, the minister decides, usually at the spur of the moment, that he will begin or end his sermon by lining out a song. Lining out is when the minister says one line of a song at a time for the congregation to repeat. The members of King David moved into a towering new structure in 1976. Although they now have a larger membership, with more professional congregants, the folk aspects of their church services remain strongly evident. Rev. Isaac Warner preaches his sermons in the traditional chanted style described previously.
