Music is indeed a language.  It communicates, stirs emotions and elicits a response.  And music is a universal phenomenon.  But language communicates consistently, and what music communicates is in no way universal but is very much culturally defined, just as in spoken language, the meaning of an arrangement of sounds (words) is not innate, but arbitrary, differing language by language.
