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?”
I am not a musician and there are MANY people that know MUCH more about music theory than me.
e.g. 6/8 time. 6 is how many beats are in a bar. 8 is how many bars. Why important? So we know when the music gets back to the start of the cycle… Kinda. There must be a beginning and an end. Why is No. of beats important? So we have an idea of the feel and how many notes roughly we can play within that. Why is 6/8 different to 3/4? Accents on a 3/4 the accent is typically on the 1 ² ³ 1 ² ³ and in a 6/8 the accent is going to mildly be on the 1 but more noticeable on the 4. Think MJ’s “The Way You Make Me Feel”. 6/8 has drive and the feeling of the accent on the UP beat.
Beyond this simplicity music is maths. Do you need to know the rules? No. Do whatever you want. But if you know the rules, you can exploit them; like musicians and composers do to create complex compositions and polyrhythms.
Hope this helps in any way.
It’s more 123 vs 123-456. In 3/4 the first of each triple is rhythmically always as strong, while in 6/8 the 1 is stronger than 4
No, the top number is beats per measure. The bottom number is how many beats are in a whole note. For example, in 6/8 time a whole note has 8 beats, making an eighth note one beat. As opposed to 3/4 time in which a quarter note is one beat.
But the exact same thing can be accomplished just by changing the tempo.
As for the accents, yeah, that’s what I gather the only difference is. But it’s never explicitly taught that way, and there’s nothing hardcoded into the logic of time signatures that suggests it must be that way.
Yeah a lot of music notation has implicit/hidden elements that aren’t ever really explained. A lot of things are done because someone “feels” like it should be that way, and no one questions it for whatever reason.
A non trivial amount of the reasoning is simplicity of reading and writing music. You could transpose everything to 4/4, but it would require a lot of weird patterns.
