musical meaning

what is it in a song that has the ability to bring out meaning to its listener? is there anything in the song itself that has these properties, or is it all in the mind? i don't know if it's because i'm feeling particularly emo today, but i was listening to miles davis's classic ballad "blue in green". for the purposes of the post, listen to this one, at least in part:

all music is, at least if given a materialist ontology, is a series of noises of different frequencies arranged in a particular way in space-time. but then how is it that these noises carry what we each understand to have meaning of some sort? is this meaning external or internal? or some combination of both? i guess here i'm drawing a parralel to the philosophy of language. i suspect some answer to this can be arrived at if we take some ideas from frege. however, even this approach would be highly problematicc.

in frege's discussion of language, there are generally two aspects to names: their sense (the cognitive associations and dimensions of the name) and their reference (what those names actually refer to). but of course it isn't obvious that music refers to anything at all.

i'm honestly not in the mood for even trying to solve this puzzle right now, but i hope i have the effort to one day tackle this issue with the seriousness it deserves.
