I am having the hell of a time in trying to convince a professional musician that, although music can be said to have a syntactic structure of sorts, the one thing that distinguishes music from language is that it definitely has no semantic structure AT ALL.
I have tried to reason about the distinction between the meaning of a linguistic expression, like, say, "He then put it on top of the other one", "Vot vopros!, niuyeli vui nie znaietie?", "Yo, desde luego, del asunto ése pues nada", or "On ne la voit pas dancer le long des golfes clairs", etc., i.e., SEMANTICS, and the meaning of the speaker (which often uses linguistic props to form premises from which to infer the messages), i.e., PRAGMATICS.
I have tried to show that almost ANYTHING in the world (from a toothpaste tube, to the Empire State Building, from the War of Crimea to Beethoven's 5th symphony, along with our semantic codes) may serve at one moment to help us convey our messages. Thus, I have argued, to say that music communicates is a platitude which amounts to say nothing at all.
To no avail!
Am I getting nuts, or are you all, linguists, in agreement with me here?
And if not, WHY NOT?
