also to reply to the also, Yeah, there's a reason sad music sounds sad, and happy music sounds happy. you don't have to be told that music is sad to understand or learn it. This is why multiple isolated parts of the world developed similar sounds for happy and sad, just as an example. they used different keys, but the ways in which the songs progress have common themes.
if you want to get into weird metaphysical stuff, you could say it has to do with the chakras, Or you could say it's based more on instinct as a result of non-musical instincts, for instance loud low noises are typically going to induce some level of fear, or at the least a jolt of adrenaline because in nature, how few things are that loud and low? typically things like earthquakes, landslides, cave-ins, etc. basically things that no living thing wants to be near for damn good reason. from there there's how its in tune with the structure of the ear, brainwaves, and even heart-rate etc. even bloodpressure and content in terms of how sound travels through the body. The shape of the inner ear has absolutely everything to do with why musical scales are the way they are, and not a few cents off, although even then it has changed subtly
For instance we used to use A436, A438, A450, and a number of other tunings. If you don't know, that's the Frequency in Hz of middle-A. since about the 1940's however, the universal standard has become A440. Now there's a TON of conspiracy theories about this involving brainwashing people, but I don't buy it, I actually understand why they did it.
Marches and anthems sound more powerfull and Resonant in A440 than the at the time standard of A438. meanwhile C-Major sounds way more uplifting in A438, and I think thigns written in G sounded better in A436, but fuck if I remember, I only read about this shit ONCE over a year ago over on "that part of the internet".
It's honestly worth listening to a few examples of different tunings, if only for the experience.
Drum-beats also make people want to dance or not based on how they sync up with the persons heart-rate. so if you start wtih something 60 or 120 syncs up with a 60 bpm heartrate, which is a very low resting point, OR it can sync up to a 120 bpm which would be high, but not full crazy dancing. 130-140 is used for dance music because at half-tempo its above a resting tempo by a little bit, but the act of following THAT tempo is enough to double the heart-rate, which then matches the actual tempo.
when you go above a healthy heartrate like 160+ you're automatically halving it, to 80, which is resting for a lot of people, which is why you don't stand up and dance to dubstep, even if it is at 160bpm. and then you get to DNB in the 180's (90 at half) which you want to start moving to but then it moves faster than you can reasonably keep up with, and from there you get into breakcore and speedcore at which point you just sort of space out and listen to, nolonger able to dance to it. if you can dance to it you're probably doing 1/3 or 1/4 time.
All because of how fast your heart is beating, and the shape of your ear.
In theory if you know all the biological reasons behind these instincts, you can make some bizzar as fuck music, but 99% of what I've seen that takes advantage of this, has been horror-movie soundtracks. the other 1% is things like Ode to Joy, and anything else in C major, ESPECIALLY when played in A438.
Interesting shit. a lot of music theory for writing songs in a particular mood, is telling you how to write in those ways, without understanding why, because music theory was created before they knew WHY it worked a certain way, just that it did.
