Jazz - a form of musical art that arose in the late XIX - early XX centuries in the United States as a result of the synthesis of African and European cultures and subsequently received widespread distribution. The characteristic features of the musical language of jazz were initially improvisation, polyrhythmia based on syncopated rhythms, and a unique set of techniques for performing rhythmic texture - swing. Further development of jazz occurred due to the development of new rhythmic and harmonic models by jazz musicians and composers.
Jazz originated as a combination of several musical cultures and national traditions. He originally came from African lands. Any African music is characterized by a very complex rhythm, the music is always accompanied by dances, which are fast tapping and swatting. On this basis, at the end of the 19th century, there was another musical genre, ragtime. Subsequently, the rhythms of ragtime in combination with blues elements gave rise to a new musical direction - jazz.
The origins of jazz are related to the blues. It arose at the end of the 19th century as a fusion of African rhythms and European harmony, but its origins should be sought from the moment slaves were imported from Africa to the New World. The slaves brought were not from the same clan and usually did not even understand each other. The need for consolidation led to the unification of many cultures and, as a result, to the creation of a single culture (including music) for African Americans. The processes of mixing African musical culture and European (which also underwent major changes in the New World) have been going on since the 18th century and in the 19th century led to the emergence of "proto-jazz" and then jazz in the conventional sense.
