Jazz and jizz
Jazz is a music genre that originated from African American communities of New Orleans in the United States during the late 19th and early 20th centuries. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American andEuropean American musical parentage with a performance orientation.[1] Jazz spans a period of over a hundred years, encompassing a very wide range of music, making it difficult to define. Jazz makes heavy use of improvisation, polyrhythms, syncopation and the swing note,[2] as well as aspects of European harmony, American popular music,[3] the brass band tradition, and African musical elements such as blue notes and African-American styles such as ragtime.[1] Although the foundation of jazz is deeply rooted within the black experience of the United States, different cultures have contributed their own experience to the music as well. Intellectuals around the world have hailed jazz as "one of America's original art forms".[4]
As jazz spread around the world, it drew on different national, regional, and local musical cultures, which gave rise to many distinctive styles. New Orleans jazz began in the early 1910s, combining earlier brass-band marches, French quadrilles, biguine, ragtime and blues with collectivepolyphonic improvisation. In the 1930s, heavily arranged dance-oriented swing big bands, Kansas City jazz, a hard-swinging, bluesy, improvisational style and Gypsy jazz (a style that emphasized musette waltzes) were the prominent styles. Bebop emerged in the 1940s, shifting jazz from danceable popular music towards a more challenging "musician's music" which was played at faster tempos and used more chord-based improvisation. Cool jazz developed in the end of the 1940s, introducing calmer, smoother sounds and long, linear melodic lines.
