The old adage, doing the same thing over wanting different results. Cliche. I like jazz music. On a good day, I love jazz music. But unlimited form changes based on piano, bass and drums with melody lines based on nineties rhythm and blues, or smooth jazz revisited for the twenty first century is beyond redundant. But with our Gemini personalities, we still tune in, listen to and sometimes even buy jazz. 

The short of it, jazz music has not changed. Original themes, whether lyrics or melody lines, predate 1945, just like literature. The last person to actually hear original jazz music was Dizzy Gillespie; he's been gone.

The Hammond was created in 1934, because pipe organs were not readily available, much less portable. Instruments other than four string bass need to hit bass registers, much less percussion, for there to be jazz. Also required, some kind of keys or bones. Pianos have bass notes, but they are not easily maintained. 808 kicks didn't exist before 1980, Miami and therefore hip hop. 

Bass is a part of jazz, required for jazz, but not jazz all by itself. Bass music is its own genre. So what is jazz? Too broad of a question, all by itself. Jazz is an amalgamation of sound (soul to soul, copyright) 

Jazz does not require audible words, so much as muffled sounds. Jazz is flexible, but it is still crazy. Deconstruct it, and you wind up tearing established instruments apart. Take the inside of a piano out; put your hand underneath the hood of a piano to muffle the sound more than your foot with pedals. Add extra, metallic implements to an existing drum set in order to create new, danceable quasi electronic dance music sound played acoustically. 

This is how complicated jazz music is. Do the three musicians exist who can accomplish all this sound as a trio? I don't know. Glasper, Hodge, Chris Daddy Dave get pretty close. But even they play remakes and covers. Shot outs to Jason Moran and African Bambata; timeless. But even he and Cory Henry lack the personalities to pull it off all by themselves. Honorable mention to Questlove and Black Thought from the Roots, for trying in 1994.
