i'm taking a class on classical music theory (fwiw i am a self-taught musician and the reason why i'm in this class is complicated) and i realized a lot of the infinitely long rules for "common practice" can be followed like 90% of the time if you just move the voices as little as possible, as alluded to in 9.9.17  9:47 am . is this a coincidence or is there something magical and/or pragmatic about moving the voices as little as possible?
i think it's kind of like how people usually remain in roughly the same geographical location, over the course of one sentence. although that is not always the case
