While blues lyrics often deal with personal adversity, the music itself goes far beyond self-pity. The blues is also about overcoming hard luck, saying what you feel, ridding yourself of frustration, letting your hair down, and simply having fun. The best blues is visceral, cathartic, and starkly emotional. From unbridled joy to deep sadness, no form of music communicates more genuine emotion.
The blues has deep roots in American history, particularly African-American history. The blues originated on Southern plantations in the 19th Century. Its inventors were slaves, ex-slaves and the descendants of slaves - African-American sharecroppers who sang as they toiled in the cotton and vegetable fields. It's generally accepted that the music evolved from African spirituals, African chants, work songs, field hollers, rural fife and drum music, revivalist hymns, and country dance music.
The blues grew up in the Mississippi Delta just upriver from New Orleans, the birthplace of jazz. Blues and jazz have always influenced each other, and they still interact in countless ways today.
Unlike jazz, the blues didn't spread out significantly from the South to the Midwest until the 1930s and '40s. Once the Delta blues made their way up the Mississippi to urban areas, the music evolved into electrified Chicago blues, other regional blues styles, and various jazz-blues hybrids. A decade or so later the blues gave birth to rhythm 'n blues and rock 'n roll.
No single person invented the blues, but many people claimed to have discovered the genre. For instance, minstrel show bandleader W.C. Handy insisted that the blues were revealed to him in 1903 by an itinerant street guitarist at a train station in Tutwiler, Mississippi.
During the middle to late 1800s, the Deep South was home to hundreds of seminal bluesmen who helped to shape the music. Unfortunately, much of this original music followed these sharecroppers to their graves.
