<P> Lavish festivals featuring African - based dances to drums were organized on Sundays at Place Congo, or Congo Square, in New Orleans until 1843 . There are historical accounts of other music and dance gatherings elsewhere in the southern United States . Robert Palmer said of percussive slave music: </P> <P> Usually such music was associated with annual festivals, when the year's crop was harvested and several days were set aside for celebration . As late as 1861, a traveler in North Carolina saw dancers dressed in costumes that included horned headdresses and cow tails and heard music provided by a sheepskin - covered "gumbo box", apparently a frame drum; triangles and jawbones furnished the auxiliary percussion . There are quite a few (accounts) from the southeastern states and Louisiana dating from the period 1820--1850 . Some of the earliest (Mississippi) Delta settlers came from the vicinity of New Orleans, where drumming was never actively discouraged for very long and homemade drums were used to accompany public dancing until the outbreak of the Civil War . </P> <P> Another influence came from the harmonic style of hymns of the church, which black slaves had learned and incorporated into their own music as spirituals . The origins of the blues are undocumented, though they can be seen as the secular counterpart of the spirituals . However, as Gerhard Kubik points out, whereas the spirituals are homophonic, rural blues and early jazz "was largely based on concepts of heterophony ." </P> <P> During the early 19th century an increasing number of black musicians learned to play European instruments, particularly the violin, which they used to parody European dance music in their own cakewalk dances . In turn, European - American minstrel show performers in blackface popularized the music internationally, combining syncopation with European harmonic accompaniment . In the mid-1800s the white New Orleans composer Louis Moreau Gottschalk adapted slave rhythms and melodies from Cuba and other Caribbean islands into piano salon music . New Orleans was the main nexus between the Afro - Caribbean and African - American cultures . </P>
