Is music just sounds?
Then what does it communicate?
Is a truck passing by music?
If I can see it, do I have to hear it too?
If while I see it I can't hear it, but hear something else, say an egg-beater, because I'm inside looking out, does the truck communicate or the egg-beater, which communicates?
Which is more musical, a truck passing by a factory or a truck passing by a music school?
