Blues is a vocal and instrumental form of music based on the use of the blue notes. It emerged in African-American communities of the United States from spirituals, work songs, field hollers, shouts and chants, and rhymed simple narrative ballads. The use of blue notes and the prominence of call-and-response patterns in the music and lyrics are indicative of African influence. The blues influenced later American and Western popular music, as it became the roots of jazz, bluegrass, rhythm and blues, rock and roll, heavy metal, hip-hop, and other popular music forms.
The phrase "the blues" is a reference to the the blue devils, meaning 'down' spirits, depression and sadness. An early reference to "the blues" can be found in George Colman's farce Blue devils, a farce in one act (1798).[1] Later during the 19th century, the phrase was used as a euphemism for delirium tremens and the police, and was not uncommon in letters from homesick Civil War soldiers.
Though the use of the phrase in African American music may be older, it has been attested to since 1912, when Hart Wand's "Dallas Blues" became the first copyrighted Blues composition.[2][3] In lyrics the phrase is often used to describe a depressed mood.[4]
There are few characteristics common to all blues, because the genre takes its shape from the idiosyncrasies of individual performances.[5] However, there are some characteristics that were present long before the creation of the modern blues.
An early form of blues-like music was a call-and-response shouts, which were a "functional expression... style without accompaniment or harmony and unbounded by the formality of any particular musical structure."[6] A form of this pre-blues was heard in slave field shouts and hollers, expanded into "simple solo songs laden with emotional content".[7] The blues, as it is now known, can be seen as a musical style based on both European harmonic structure and the African call-and-response tradition, transformed into an interplay of voice and guitar.[8]
Many blues elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa. The Diddley bow, a homemade one-stringed instrument found in parts of the American South in the early twentieth century, and the banjo, are African-derived instruments that may have helped in the transferral of African performance techniques into the early blues instrumental vocabulary.
Blues music later adopted elements from the "Ethiopian airs", minstrel shows and Negro spirituals, including instrumental and harmonic accompaniment.[9] The style also was closely related to ragtime, which developed at about the same time, though the blues better preserved "the original melodic patterns of African music".[10]
Blues songs from this period, such as Lead Belly's or Henry Thomas's recordings, show many different structures. The twelve-, eight-, or sixteen-bar structure based on tonic (I), subdominant (IV) and dominant chords (V) became the most common forms.[11] What is now recognizable as the standard 12-bar blues form is documented from oral history and sheet music appearing in African American communities throughout the region along the lower Mississippi River, in Memphis, Tennessee's Beale Street, and by white bands in New Orleans.
The original lyrical form of the blues was probably a single line, repeated four times. It was only later that the current, most common structure of a line, repeated once and then followed by a single line conclusion, became standard.[12] These lines were often sung following a pattern closer to a rhythmic talk than to a melody.
Early blues frequently took the form of a loose narrative. The singer voiced often his or her "personal woes in a world of harsh reality: a lost love, the cruelty of police officers, oppression at the hands of white folk, [and] hard times".[13] Many of the oldest blues records contain gritty, realistic lyrics, in contrast to much of the popular music being recorded at the time. For example, "Down in the Alley" by Memphis Minnie, is about a prostitute having sex with men in an alley.
Music such as this was called "gut-bucket" blues, a term which refers to a type of homemade bass instrument made from a metal bucket used to clean pig intestines for chitterlings (a soul food dish associated with slavery). "Gut-bucket" blues songs are typically "low-down" and earthy, about rocky or steamy man-woman relationships, hard luck and hard times. Gut-bucket blues and the rowdy juke-joint venues where it was played, earned blues music an unsavory reputation; church-goers shunned it and some preachers railed against it.
Author Ed Morales has claimed that Yoruba mythology played a part in early blues, citing Robert Johnson's "Cross Road Blues" as a "thinly veiled reference to Eleggua, the orisha in charge of the crossroads".[14] However, many seminal blues artists such as Son House, or Skip James had in their repertoire several religious songs or spirituals. Reverend Gary Davis and Blind Willie Johnson are examples of artists often categorized as blues musicians for their music but whose lyrics clearly belong to the spirituals.
Although the blues gained an association with misery and oppression, the blues could also be humorous and raunchy as well:
"Rebecca, Rebecca, get your big legs off of me,
Rebecca, Rebecca, get your big legs off of me,
It may be sending you baby, but it's worrying the hell out of me."[citation needed]
In particular, Hokum blues celebrated both comedic lyrical content and a boisterous, farcical performance style. Tampa Red's classic "Tight Like That" is a sly wordplay with the double meaning of being "tight" with someone coupled with a more salacious physical familiarity.
Lyrical content of music became slightly simpler in post war blues in which focus was often almost exclusively on singer's sexual worries. Many lyrical themes that frequently appeared in pre war blues such as economic depression, transportation, technology, horses, cows, devils, gambling, magic, floods and dry periods were mostly left out in post war blues.
