Well... I believe that music can generate certain emotions and feelings in people. But an A minor chord is always going to be just that. It's just a chord. In order to "generate" emotion you need to focus of the chord progression. One chord ain't gonna do it.
Everyone here is right. Music is a lot like literature. It can be interpreted in any way the listener wants to. But to say that music can't generate emotions is pretty extreme. Personally I don't like a lot of music because they do nothing to me. There is music, however, that moves me BIG TIME! Sometimes it may take me several times to listen to a piece before I "feel" anything. Personally, soundtracks do the trick. (Some soundtracks I haven't even seen the movie to.
James Newton Howard... Listen to some of his work I bet you will be moved!
