As a musician, I find this statement,
"How many here can argue the complexities of “jazz.” Frankly, unless you’re a musician educated in jazz, who can truly play, it’s beyond your comprehension. So in essence, there’s no argument to be had."
funny.
You don't have to be "educated" in jazz to discuss its complexity or lack thereof. You only need to have some musical education and appreciation. Even assigning a complexity to music is probably a fools game. What makes a music complex? There is no official definition. If you just look at total variety of harmony, rhythm, melody, and dynamic structure, classical is always going to win. It is any wonder. We are talking about pieces of music crafted over months or years, for a large number of instruments.
So what makes Jazz complex and is it all jazz, or just jazz that does not follow typical musical structures in which case is it complex, or just different? Some would consider this music very complex: https://www.youtube.com/watch?v=_LxXw2OiL6Q . Interestingly it bears similarity to some jazz music. Which came first?
All music is beautiful to those that enjoy that particular music. Jazz, old country, new country, classical, pop, rock, rap, hip-hop.
