Good way to miss my point there, lad.
English and Chinese have the same purpose: they have different means to achieving this purpose, but this purpose is eventually achieved. This purpose, conveying information. Hell, they even share some aspects.
Music and, say, auto repair do not have the same purpose. That is plain to see.
However- much like Chinese and English, traditional, twelve-tone-to-the-octave western music has the same purpose as, say, 24 tone to the octave music, or 43 tone to the octave music. And, funnily enough, again like Chinese and English, managed to share some aspects; pitches, rhythms, and so on.
No matter WHAT we do musically, what tools we do it with- what tonal system, what chords, what instrument, the purpose is the same: to make something that sounds good and makes the people listening FEEL good.
I don't care if I use thousand-tone-to-the-octave, completely weird chords with 15 different pitches in it. As long as that purpose is fulfilled, it's STILL music.
Chinese and English are different, yes. But they're both STILL languages, and both fulfil their purpose, and even manage to share stuff while doing it.
