I found this interesting video here
"The global village is a world in which you don’t necessarily have harmony. You have extreme concern with everybody else’s business and much involvement in everybody else’s life. It’s a sort of Ann Landers column writ large… huge involvement in everybody else’s affairs. So the Global Village is as big as a planet and as small as the village post office."
So my understanding is that "harmony" means every chord manages their own, while a global village everyone is connected.
But "harmony" has another meaning, if everyone creates a sound by random it's likely only noise, everyone have to adapt specific sound patterns (e.g. the triad C-E-G ) in order to create "harmony". So in this sense, to create harmony, you do have to concern others.
So is the word "harmony" used properly in the above video context? Or am I missing something here?
Can anyone share more about the usage of "harmony" in daily English?
