Jazz music is a very popular form of music, this form of music has been a popular genre since the early 20th century, mostly present and evident in African American neighborhoods and then spread across America and Europe. Jazz has always influenced popular, more mainstream music, over the years it has gone through many evolutions, producing many different sub genres as time has gone on. Jazz is also influenced by the different cultures and regions it is brought into, with each culture adding its' own distinct twist on the genre. This has created many distinctive and different styles in jazz culture.
Early jazz movements also had a kind of call-and-response pattern, in which some players would play a note, only to have other people playing different instruments play the same thing, and so on it would go, making the genre a little bit competitive during live performances. Many early jazz musicians did not even know how to play music. However, this is certainly not to say that jazz players are not talented - they certainly are very talented, often more than classical performers.
