For me it’s time signatures in music. I grew up playing instruments, played in several orchestras, etc. But no matter how many times someone tries to explain time signatures to me, it makes no sense. I don’t understand why people place such importance on it. To me, notes have a pitch and a duration, maybe some dynamics. That’s it. I don’t understand why people try to needlessly complicate it. It doesn’t give you anything.
My wife will hear a song and go “Oh neat, it’s in 5/8.” And I’m like “How tf do you know that, and why does it matter?”


That one took me a moment as well … why is there a difference between 2/2 and 4/4, or 6/8 and 3/4 …
It started to make sense once I saw it as an abstraction. It denotes a certain emphasis on certain notes that would look really awkward and hard to read if it was repetitively written out for every note (not that I can really read music anyway).
I have a much harder time with harmony theory … like, I get that some successions have a “resolving” feel but other than that I never got why I shouldn’t just jumble up pitches any way that sounds ok to me. Ultimately I decided that I’ll spend my life composing music, deliberately ignoring harmony theory as material …
Other things that elude me a mostly social nature … like, some people are just amazing at striking up some or another deal or barter their way through life at a discount, simple because they connect well to people. I never got how they do that … not sure whether it’s something you can learn
Well, we have a word for jumbling them up however you feel like: jazz 🙃
Okay, more serious response, at the end of the day it is all about having it sound good. No one’s going to question why you did things a certain way, if it sounds good.
I try to see it more as a shortcut for making things sound good. It’s just a set of known-good strategies that you can apply, if you feel like it.
Like a tube with premixed color. Yes, you can mix your own color, and many times it is necessary to get it just right, but sometimes you just know that a few dots of khaki are what you want.
Well the beauty of music is that you can do exactly this and it’s fine.
Pretty much all “music theory” is Western-dominated anyway and far from all-encompassing.
There was a really good YouTube video about this a few years back, by I think Adam Neely. Let me see if I can dig it up.

Very good video.
One thing this reminded me of is Bootsy Collins explaining funk. How when you’re playing bass you put the root on the one. https://youtu.be/H2MMuNkCLZY
The time signature is about emphasis, and there are common ones. I’ve bolded and italicized big and small emphases on the beat numbers.
Common time: 1 2 3 4 , 1 2 3 4 ,… example peter gunn theme
Cut time: 1 2, 1 2, … example stars and stripes forever
Waltz: 1 2 3, 1 2 3, … example the blue danube
6/8: 1 2 3 4 5 6, 1 2 3 4 5 6,… example the wreck of the edmund fitzgerald
5/4: 1 2 3 4 5, 1 2 3 4 5,… example Mission Impossible theme
Some time signatures are very similar, like waltz and 6/8, the difference is where the emphasis is placed. Waltz has just one big, emphasis placed on the one, where 6/8 is also groups of three, but has a big emphasis on the 1 and a smaller emphasis on the 4th beat. An alternate way to count in 6/8 time is 1 2 3, 2 2 3; 1 2 3, 2 2 3;… which emphasizes how 6/8 time feels like two groupings of three, within one bar, with the biggest emphasis on the one.
This is the basic version – composers will play with expectations and add their own accents on top, etc., so you won’t always hear the emphasis as I described. Reasonable people might even disagree about whether a piece of music is better described by one time signature or another, because they can be so similar.
I was in band growing up and i also couldn’t explain time signatures even though i was able to read music and play them; it is something you learn without necessarily being able to verbalize, since it is about how the music feels, based on subtle emphasis.
