There's a lot of "feels" that you cannot represent without that. But these aren't studied formally, funk, latin, caribean music. Jazz is but I think the people studying jazz don't explain everything because they're talking among themselves and already have internalized all this. So they just write "swing this" above a measure and the cats will deal with it.
oh: and I just thought of something else. The idea of prediction; since I relate everything to physics, often feels similar to a sense of internal balance. I mean your body position, as in not tripping. Syncopated music often feels like falling. Maybe it's synesthesia but considering that all these music were linked to parties and dance I think it's not far fetched that our musical prediction is the same as the one that tries to predict how to balance movements and body.
Swing feel isn't a closely guarded secret among jazz musicians - it just isn't quick to explain. There's a sliding scale of the ratio between the first and second eighth note, where at slow tempos it's 2:1, and at fast tempos it's 1:1. The exact ratio at a given tempo is something that's passed down aurally. There's also a harder articulation on the second eighth note. There are other nuances too, but those are the most important ones.
The 1,2 ratio is nice, but I use to see response curves... a bit like interpolated splines...
Thus, when listening to syncopation, you constantly comparing what your brain hears to a steady 4/4 it ‘expects' to hear. And when listening to a soloist improvise, you are comparing the notes your brain hears to the melody it ‘expects’ to hear.
This is obviously not the only effect, not by a long shot, but is that what you mean by “inertia?"
