Why Does All Jazz Sound The Same?

@jjss49,
the gift that never stops giving 🙏🙏🙏🙏

So on the mark. Thanks for sharing your experience,  lucky you to have such a roommate. 

A very good friend of mine is  a drummer and his brother is  a pianist.  Both are accomplished jazz musicians on our local scene. It was incredibly helpful in my development when I'd listen to them practice and attend their weekend shows. Talk about training one's ear with all of that frequent up close exposure to live instruments.

I agree, Jazz is really growing on me. It's perfect as background music because it's rarely annoying and I'm finding more and more that I like. I'm very "young" in Jazz so I don't know all the great go-to's but for now I'm liking the normals I guess: Bob James, Dave Grusin, and a few others I can't pronounce.  

Once upon a time, I thought all bourbon tasted the same. Once upon a time, I  thought all rock guitar riffs sounded the same.  Once upon a time, I thought country music sounded the same. 

It seems the more I listen to different types of music, the easier it is to appreciate all types of music.

Of course it all sound's the same ... they all play the same twelve notes ... 🙄

There are many branches and styles within jazz.  It is beautiful, often soulfull music.  Many of the greatest popular artists are influenced by jazz - Steely Dan, Joni Mitchell, Anita Baker, just to name a few.  It is a wonderful original art form from America, that now has broad followings around the world.
