Jazz grew out of the music of African slaves and free black people in the U.S., and from secular work songs and "field hollers." The style now known as jazz, a largely instrumental idiom at first, evolved in the city of New Orleans in the late 19th century and early 20th century. The genre most often uses a basic 2/4 or 4/4 time signature, but other time signatures have become common.
Be-bop was first developed in the 1940s by such musicians as Dizzy Gillespie, Charlie Parker and Thelonious Monk. Be-bop or re-bop was commonly used in scat singing to accompany the distinctive two-note rhythm. The melody of the tune is complemented or reinforced by on and off beat punctuations.
Boogie-woogie is a percussive style of piano blues favored for its volume and momentum.
Fusion emerged in the mid 1970s. It's jazz that has been blended with such musical styles as rock, soul music, pop, funk and folk music.
Straight ahead is a term describing a conventional, simple or straightforward approach to playing in the bop style and its derivatives.
Some of the artists who defined the art of jazz are: Bessie Smith, Jelly Roll Morton, Louis Armstrong, Fletcher Henderson, Duke Ellington, Count Basie, Billie Holiday, Art Tatum, Charlie Parker, Thelonious Monk, Modern Jazz Quartet and Miles Davis.
The Tampa Bay area lost one of its major jazz outlets when the "WAVE" changed format last year, but radio stations WMNF and WUSF have picked up the slack. WMNF FM-88.5 broadcasts jazz weekdays from 11 to 2 p.m. and Sunday from 7 to 10 p.m. WUSF FM-89.7 plays jazz Sunday at midnight, Monday through Friday from 11 p.m. to 6 a.m. and Saturdays from 8 p.m. to Sunday at 6:30 a.m.
