Step-by-step explanation:
The music of the blacks in New Orleans reflected a mixture of African and European musical styles. Unlike the Creoles of Color, who were influenced more by European musical styles, the music of the blacks incorporated elements of African rhythms, syncopation, and improvisation, combined with European harmonic structures. This unique blend of musical traditions created a distinctive sound that became known as jazz, which reflected a high level of technical fluency.
