Blues music

Blues is a music genre and musical form which originated in the Deep South of the United States around the 1860s. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads from the African-American culture. The blues form is ubiquitous in jazz, rhythm and blues, and rock and roll, and is characterized by the call-and-response pattern (the blues scale and specific chord progressions) of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds, fifths or sevenths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove.

Blues as a genre is also characterized by its lyrics, bass lines, and instrumentation. Early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the AAB pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars. Early blues frequently took the form of a loose narrative, often relating the racial discrimination and other challenges experienced by African-Americans.

Many elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa. The origins of the blues are also closely related to the religious music of the Afro-American community, the spirituals. The first appearance of the blues is often dated to after the ending of slavery and, later, the development of juke joints. It is associated with the newly acquired freedom of the former slaves. Chroniclers began to report about blues music at the dawn of the 20th century. The first publication of blues sheet music was in 1908. Blues has since evolved from unaccompanied vocal music and oral traditions of slaves into a wide variety of styles and subgenres. Blues subgenres include country blues, such as Delta blues and Piedmont blues, as well as urban blues styles such as Chicago blues and West Coast blues. World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience, especially white listeners. In the 1960s and 1970s, a hybrid form called blues rock developed, which blended blues styles with rock music.

Etymology

The term ''Blues'' may have come from "blue devils", meaning melancholy and sadness; an early use of the term in this sense is in George Colman's one-act farce ''Blue Devils'' (1798). The phrase ''blue devils'' may also have been derived from a British usage of the 1600s referring to the "intense visual hallucinations that can accompany severe alcohol withdrawal".Devi, Debra (2013). "Why Is the Blues Called the 'Blues'?" ''Huffington Post'', 4 January 2013
Retrieved November 15, 2015. As time went on, the phrase lost the reference to devils, and it came to mean a state of agitation or depression. By the 1800s in the United States, the term ''blues'' was associated with drinking alcohol, a meaning which survives in the phrase '' blue law'', which prohibits the sale of alcohol on Sunday. Though the use of the phrase in African-American music may be older, it has been attested to in print since 1912, when Hart Wand's " Dallas Blues" became the first copyrighted blues composition.

In lyrics the phrase is often used to describe a depressed mood.

In 1827, it was in the sense of a sad state of mind that John James Audubon wrote to his wife that he "had the blues".

The phrase "the blues" was written by Charlotte Forten, then aged 25, in her diary on December 14, 1862. She was a free-born black woman from Pennsylvania who was working as a schoolteacher in South Carolina, instructing both slaves and freedmen, and wrote that she "came home with the blues" because she felt lonesome and pitied herself. She overcame her depression and later noted a number of songs, such as "Poor Rosy", that were popular among the slaves. Although she admitted being unable to describe the manner of singing she heard, Forten wrote that the songs "can't be sung without a full heart and a troubled spirit", conditions that have inspired countless blues songs.

Lyrics

The lyrics of early traditional blues verses often consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the so-called "AAB" pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars. Two of the first published blues songs, " Dallas Blues" (1912) and " Saint Louis Blues" (1914), were 12-bar blues with the AAB lyric structure. W.C. Handy wrote that he adopted this convention to avoid the monotony of lines repeated three times. The lines are often sung following a pattern closer to rhythmic talk than to a melody.

Early blues frequently took the form of a loose narrative. African-American singers voiced their "personal woes in a world of harsh reality: a lost love, the cruelty of police officers, oppression at the hands of white folk, ndhard times". This melancholy has led to the suggestion of an Igbo origin for blues because of the reputation the Igbo had throughout plantations in the Americas for their melancholic music and outlook on life when they were enslaved.

The lyrics often relate troubles experienced within African American society. For instance Blind Lemon Jefferson's "Rising High Water Blues" (1927) tells of the Great Mississippi Flood of 1927:

Although the blues gained an association with misery and oppression, the lyrics could also be humorous and raunchy:

Hokum blues celebrated both comedic lyrical content and a boisterous, farcical performance style. Tampa Red and Georgia Tom's "It's Tight Like That" (1928) is a sly wordplay with the double meaning of being " tight" with someone, coupled with a more salacious physical familiarity. Blues songs with sexually explicit lyrics were known as dirty blues. The lyrical content became slightly simpler in postwar blues, which tended to focus on relationship woes or sexual worries. Lyrical themes that frequently appeared in prewar blues, such as economic depression, farming, devils, gambling, magic, floods and drought, were less common in postwar blues.

The writer Ed Morales 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".Morales, p. 277. However, the Christian influence was far more obvious. The repertoires of many seminal blues artists, such as Charley Patton and Skip James, included religious songs or spirituals. Reverend Gary Davis and Blind Willie Johnson are examples of artists often categorized as blues musicians for their music, although their lyrics clearly belong to spirituals.

Form

The blues form is a cyclic musical form in which a repeating progression of chords mirrors the call and response scheme commonly found in African and African-American music. During the first decades of the 20th century blues music was not clearly defined in terms of a particular chord progression. With the popularity of early performers, such as Bessie Smith, use of the twelve-bar blues spread across the music industry during the 1920s and 30s. Other chord progressions, such as 8-bar forms, are still considered blues; examples include " How Long Blues", " Trouble in Mind", and Big Bill Broonzy's " Key to the Highway". There are also 16-bar blues, such as Ray Charles's instrumental "Sweet 16 Bars" and Herbie Hancock's " Watermelon Man". Idiosyncratic numbers of bars are occasionally used, such as the 9-bar progression in " Sitting on Top of the World", by Walter Vinson.

The basic 12-bar lyric framework of a blues composition is reflected by a standard harmonic progression of 12 bars in a 4/4 time signature. The blues chords associated to a twelve-bar blues are typically a set of three different chords played over a 12-bar scheme. They are labeled by Roman numbers referring to the degrees of the progression. For instance, for a blues in the key of C, C is the tonic chord (I) and F is the subdominant (IV).

The last chord is the dominant (V) turnaround, marking the transition to the beginning of the next progression. The lyrics generally end on the last beat of the tenth bar or the first beat of the 11th bar, and the final two bars are given to the instrumentalist as a break; the harmony of this two-bar break, the turnaround, can be extremely complex, sometimes consisting of single notes that defy analysis in terms of chords.

Much of the time, some or all of these chords are played in the harmonic seventh (7th) form. The use of the harmonic seventh interval is characteristic of blues and is popularly called the "blues seven". Blues seven chords add to the harmonic chord a note with a frequency in a 7:4 ratio to the fundamental note. At a 7:4 ratio, it is not close to any interval on the conventional Western diatonic scale. For convenience or by necessity it is often approximated by a minor seventh interval or a dominant seventh chord.

In melody, blues is distinguished by the use of the flattened third, fifth and seventh of the associated major scale.

Blues shuffles or walking bass reinforce the trance-like rhythm and call-and-response, and they form a repetitive effect called a groove. Characteristic of the blues since its Afro-American origins, the shuffles played a central role in swing music. The simplest shuffles, which were the clearest signature of the R&B wave that started in the mid-1940s, were a three-note riff on the bass strings of the guitar. When this riff was played over the bass and the drums, the groove "feel" was created. Shuffle rhythm is often vocalized as "''dow'', da ''dow'', da ''dow'', da" or "''dump'', da ''dump'', da ''dump'', da": it consists of uneven, or "swung", eighth notes. On a guitar this may be played as a simple steady bass or it may add to that stepwise quarter note motion from the fifth to the sixth of the chord and back.

History

Origins

The first publication of blues sheet music may have been "I Got the Blues", published by New Orleans musician Antonio Maggio in 1908 and described as "the earliest published composition known to link the condition of having the blues to the musical form that would become popularly known as 'the blues.'" Hart Wand's " Dallas Blues" was published in 1912; W.C. Handy's " The Memphis Blues" followed in the same year. The first recording by an African American singer was Mamie Smith's 1920 rendition of Perry Bradford's "Crazy Blues". But the origins of the blues were some decades earlier, probably around 1890. This music is poorly documented, partly because of racial discrimination in U.S. society, including academic circles,Kunzler, p. 130. and partly because of the low rate of literacy among rural African Americans at the time.

Reports of blues music in southern Texas and the Deep South were written at the dawn of the 20th century. Charles Peabody mentioned the appearance of blues music at Clarksdale, Mississippi, and Gate Thomas reported similar songs in southern Texas around 1901–1902. These observations coincide more or less with the recollections of Jelly Roll Morton, who said he first heard blues music in New Orleans
