Homemade Jamz Blues Band

Blues is the name given to both a musical form and a music genre created within the African-American communities in 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 which is ubiquitous in jazz, rhythm and blues and rock and roll is characterized by the use of specific chord progressions ? the twelve-bar blues chord progressions being the most frequently encountered ? and the blue notes sung or played for expressive purposes at a slightly lower pitch than that 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 in 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, blues evolved into a hybrid form called blues rock. In the 1990s, punk blues appeared as an outgrowth of punk rock claiming a direct Delta blues influence.

The term "the blues" refers to the "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).The "Trésor de la Langue Française informatisé" provides this etymology to the word blues and George Colman's farce as the first appearance of this term in the English language, see http://atilf.atilf.fr/dendien/scripts/fast.exe?mot=blues 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.Davis, Francis.
