If we hear someone speaking a language that is foreign to us, it might sound like random gibberish...but obviously, that's a misperception.
Well, the same misperception occasionally happens when we first hear a music style that is foreign to us.
What you are currently perceiving as "random and weird," with a drummer who has decided to "just hit whatever" is not the reality of jazz at all. My guess is that you simply didn't grow up in a household where jazz was the music being played on a daily basis. In essence, jazz is foreign to you.
If you decide to actually learn it, you'll need to do the exact opposite of "tune out everything." You'll need to start listening very intently and frequently, along with getting some guidance on the standard rhythms and the standard songs. It's already been mentioned numerous times on this forum, but John Riley's book, The Art of Bop Drumming, is a nice place to start. It'll show you some of the basic rhythms to get started, and it'll even recommend your first handful of jazz albums (Moanin' and Milestones amongst others).
Have fun, and best of luck!
I have that exact thing with ICM (Indian classical music) at first it was sort of pleasant noise (I mean I intellectually knew there was more to it, I'm just talking musical perception here)
THEN I could hear that there WAS a structured language, but the structure eluded me..I mean I just started to pick up on the patterns.
LATER I could IDENTIFY the patterns.
It's an ongoing process and I do wonder if, like language, some of my neural-perceptual circuitry is ingrained deeply now - but the process has been cool
(and no, I'm not remotely ready for tabla..oh it'd be cool, but above my pay grade -- which is zero BTW)
It does remind me of every kids first fake (and you know you are faking it, just for funsies to do it) walking bass line where one just chromatically go up and down maybe with a little swing in the rhythm.
still...that 'pretend' is a step...it does contain the germ of the idea of linearizing the harmony (as in an arpeggio, then with passing tones, etc)
funny how we so often think of it as "jazz" but it also exists in classical voice leading (harmonize the cantus firmus)
eh, I'll start going down the harmonic rabbit hole, so back to our regularly scheduled program of RHYTHM
