From the religious revival movements among white and black Americans during the 19th century, poured several songwriters and musicians who molded the traditional gospel sound.
By the beginning of the 20th century, new music in the American canon expanded, with the likes of blues, folk/country, jazz and ragtime, providing new harmonies and rhythms that gospel music incorporated.
Gospel became less serious and more upbeat and lively. Singers were voracious and melismatic (vocal runs). Instrumental and vocal accompaniment was ushered in, which drew bigger audiences.
Choirs were introduced to support the call-and-response tradition during sermons. Gospel quartets drew from spirituals, using four-part harmonies while keeping bright melodies.
Some of the influencers of traditional gospel were: The Carter Family, Thomas A. Dorsey, Reverend C.A. Tindley, and John Willard Peterson, The Soul Stirrers.
