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, as well as aspects of European harmony, American popular music, the brass band tradition, and African musical elements such as blue notes and African-American styles such as ragtime.
Although the foundation of jazz is deeply rooted within the black experience of the United States, different cultures have contributed their own experience and styles to the art form as well.
Intellectuals around the world have hailed jazz as "one of America's original art forms".
BEBOP or bop is a style of jazz developed in the early to mid-1940s in the United States, which features songs characterized by a fast tempo, complex chord progressions with rapid chord changes and numerous changes of key, instrumental virtuosity, and improvisation based on a combination of harmonic structure, the use of scales and occasional references to the melody.
JAZZ standards are musical compositions which are an important part of the musical repertoire of jazz musicians, in that they are widely known, performed, and recorded by jazz musicians, and widely known by listeners. There is no definitive list of jazz standards, and the list of songs deemed to be standards changes over time. Songs included in major fake book publications (sheet music collections of popular tunes) and jazz reference works offer a rough guide to which songs are considered standards.
Here is a song called "Blue Bossa".
