blues

Blues is the name given to both a musical form and a music genre that originated in African-American communities of primarily the Deep South of the United States at the end of the 19th century from spirituals, work songs, field hollers, shouts and chants, and rhymed simple narrative ballads. The blues form ubiquitous in jazz, rhythm and blues, and rock and roll is characterized by specific chord progressions—the twelve-bar blues chord progressions being the most common—and the blue notes, notes that for expressive purposes are sung or played flattened or gradually bent (minor 3rd to major 3rd) in relation to the pitch of the major scale.

The blues genre is based on the blues form but possesses other characteristics such as specific lyrics, bass lines and instruments. Blues can be subdivided into several subgenres ranging from country to urban blues that were more or less popular during different periods of the 20th century. Best known are the Delta, Piedmont, Jump and Chicago blues styles. World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience. In the 1960s and 1970s, a hybrid form called blues rock evolved.

The term "the blues" refers to the "blue devils", meaning melancholy and sadness; an early use of the term in this sense is found in George Colman's one-act farce Blue Devils (1798). 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.In lyrics the phrase is often used to describe a depressed mood.Most blues fans are very familiar with the work of blues guitar legend Jimmy Dawkins. Not everyone is aware of his work as a record producer with his own label, Leric Records. In the 1980s, the label released 45s by Tail Dragger, Queen Sylvia Embry, Little Johnny Christian and Nora Jean Wallace, to name a few.

Since the 1980s, there has been a resurgence of interest in the blues among a certain part of the African-American population, particularly around Jackson, Mississippi and other deep South regions. Often termed "soul blues" or "Southern soul", the music at the heart of this movement was given new life by the unexpected success of two particular recordings on the Jackson-based Malaco label: Z. Z. Hill's Down Home Blues (1982) and Little Milton's The Blues is Alright (1984). Contemporary African-American performers who work this vein of the blues include Bobby Rush, Denise LaSalle, Sir Charles Jones, Bettye LaVette, Marvin Sease and Peggy Scott-Adams.

During the 1980s, blues also continued in both traditional and new forms. In 1986, the album Strong Persuader revealed Robert Cray as a major blues artist. The first Stevie Ray Vaughan recording, Texas Flood, was released in 1983, and the Texas-based guitarist exploded onto the international stage. 1989 saw a revival of John Lee Hooker's popularity with the album The Healer. Eric Clapton, known for his performances with the Blues Breakers and Cream, made a comeback in the 1990s with his album Unplugged, in which he played some standard blues numbers on acoustic guitar. However, beginning in the 1990s, digital multitrack recording and other technological advances and new marketing strategies that include video clip production have increased costs, and challenge the spontaneity and improvisation that are an important component of blues music.

In the 1980s and 1990s, blues publications such as Living Blues and Blues Revue began to be distributed, major cities began forming blues societies, outdoor blues festivals became more common, and more nightclubs and venues for blues emerged.

In the 1990s, blues performers explored a range of musical genres, as can be seen, for example, from the broad array of nominees of the yearly Blues Music Awards, previously named W. C. Handy Awards or of the Grammy Awards for Best Contemporary and Traditional Blues Album. Contemporary blues music is nurtured by several blues labels such as: Alligator Records, Ruf Records, Chess Records (MCA), Delmark Records, Northern Blues Music, and Vanguard Records (Artemis Records). Some labels are famous for their rediscovering and remastering of blues rarities such as Arhoolie Records, Smithsonian Folkways Recordings (heir of Folkways Records) and Yazoo Records (Shanachie Records).
