Dalecrommie,
Youre right. Extrinsically, there is only sound. Sound only becomes music when it strikes a musical chord within us. I surmise that there are lesser creatures in the world that may hear the same sound we do, but are unable to hear it musically because they arent wired for that. Sound can be measured scientifically by instruments. The only method I know of for measuring music, is by observing the tapping of toes, etc.
