Blues music, one of the most influential genres in modern music, has its origins in the African American communities of the southern United States during the late 19th century. Rooted in spirituals, work songs, and field hollers, the blues expressed the hardships, hopes, and emotions of people who had faced centuries of slavery and discrimination. The music often featured a twelve-bar structure, repetitive lyrics, and expressive melodies that reflected deep personal feelings. Early blues musicians, such as W.C. Handy and Bessie Smith, played a pivotal role in popularizing the genre. Over time, the blues evolved and influenced many other musical styles, including jazz, rock, and rhythm and blues. Its emotional depth and historical significance make it a cornerstone of American cultural history.
