All definitions of the word "music" that anyone has ever come up with are wrong.

We only know what the word "music" means from our own subjective experience of listening to specific examples of music.

At most we can observe common features of musical items, and include a description of those features in a definition. But such a definition will fall way short of accurately separating what is music from what is not music.

There are other subjective phenomena that we have words for, but for most subjective phenomena we have _some_ objective understanding of what is going on.

Music seems to win the prize for being both very familiar _and_ very mysterious.
