Music Story

American blues singer Ma Rainey (1886-1939), the "Mother of the Blues" 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 T...

Blues is a music genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs, spirituals, and European folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads.

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...

Bluegrass music is a form of American roots music, and a related genre of country music. Influenced by the music of Appalachia, bluegrass has mixed roots in Irish, Scottish and English traditional music, and was also later influenced by the music of African-Americans through incorporation of jazz elements. Settlers from Britain and Ireland arrived in Appalachia during the 18th century, and brought with them the musical traditions of their homelands. These traditions consisted primarily of English and Scottish ballads—which were essentially unaccompanied narrative—and dance music, such as Irish reels, which were accompanied by a fiddle. Many older bluegrass songs come directly from the British Isles. Several Appalachian bluegrass ballads, such as "Pretty Saro", "Cuckoo Bird" and "House Carpenter", come from England and preserve the English ballad tradition both melodically and lyrically.  Others, such as The Two Sisters, also come from England; howe...
