First of all, what is this "jazz" of which I speak?
Well, I might best be able to answer that question by telling you what it isn't.
Jazz is not what they are playing on WNUA in Chicago. They used to call it New Age music (hence the call letters); now they call it "smooth jazz." Nuh-uh. It's fusion, or what started out as "jazz fusion" in the late 60's/early 70's. It was jazz harmony and jazz improvisation over a rock beat - a fusion of jazz and rock.
Jazz is its own language, with its own harmonies and its own beat. It was born into the world in the early part of the last century, itself a fusion of marches, ragtime, African rhythms, and the vocalizing of slaves. Like it or not, it was born with a swing beat, and the people of the time heard it and they labeled it: they called it jazz. Take away the swing beat, or the tight, colorful harmonies, or the extensive use of improvisation, and it becomes something else. Then it is up to us to figure out what to call it. Just stop calling it jazz. Call it New Age, call it fusion, call it world music - just don't call it jazz.
Music is a language. They call it a universal language, and it is in the sense that it is everywhere. But there are different "tongues" within the broader language called Music. Every country on earth has its own music which is unique to that country. And within a country's music are (or can be) different genres of music. Again, like it or not, different genres of music have been given labels. Here in America, we can hear a piece of music and recognize it as being classical music, rock, jazz, hip-hop, folk, country, bluegrass, or even "smooth jazz." Music, like any true language, is labeled or categorized according to how it sounds. [Note: If someone out there comes up with a new musical style, please don't call it "jazz." It's already been taken.]
Ever notice how music stores are organized? Would you expect to find Kenny G in the same section that you would find Boston? Or in the same section that you would find Eminem, or Beethoven? No. Why? Because he is not speaking their language. Beethoven shares a section in the music store with Mozart, Bizet, and Rachmaninoff. Eminem and Boston share their sections with artists who use the same musical language they are using.
So, someone explain to me why Kenny G shares a section in the music store with Count Basie, Louis Armstrong, and Benny Goodman. Are they really playing the same kind of music? Basie, Armstrong, and Goodman are playing jazz. Kenny isn't.
Categorizing music is like categorizing any language: its purpose is to avoid confusion. There are artists who make a big deal out of not being categorized. This is usually done out of pride, as their music is usually rooted in a definitive style. Put it this way: if their music was so totally unique, no one would be trying to fit it into a category in the first place. They couldn't. They'd start making up names for it, like "jazz."
So, when I am talking jazz, I am talking about that swingin' music made famous by Armstrong, Ella Fitzgerald, Glenn Miller, Duke Ellington, and others like them. Not fusion, not "smooth jazz" or New Age. I'm talking about the real thing.
Actually, I won't be saying much about jazz as I have "labeled" it here. I will be talking more about issues that have hurt jazz and its standing in American pop culture, things that have relegated it to the sidelines and have made "America's music" not much more than a cultural novelty, being kept alive by Ken Burns and the Smithsonian Institute.
