There is no point to it. It is play in musical form. One has to be quite skilled as a musician to play jazz. There is a lot of creativity, spontaneity and trying new things.
There is no point other than the fact that some people find the collection of pitches that the genre produces is pleasing to a large number of people. The same as with any other music.
if you don't get it, no point trying to explain it
to do an arm full of hash and to make some cool music man.
To perform great music for people to enjoy! Dance to! And listen to in a high class club that you should bring a date to!
I think maybe when you see the men in white jackets coming you may do better by making a run for it... They're comng to take you away!
I never could figure it out for sure... and I'm a musician. Near as I can figure, it useful in helping white people feel very cosmopolitan. ;}
It's music, enjoyed by millions
