Does music really have its own language?

Hiya tattu, The Music of "Braveheart" tells a story with the Music by itself it´s really well written and composed. The Music has a lot of emotionally charged components in it you would have to listen to it yourself if you have not done so already to know what I mean. For example the oboe I think that plays in it comes up with the emotion of sadness and the situation is sad. So for me music does have a language of it´s own. Very hard to explain really in words. The Film Braveheart is an example. Music was composed by James Horner I believe so.
