With music it is different. Language is not controlled by an universal law. Sound is. Musical doesn't mean something that is pleasing to the ear. Sometimes a dictionary says that music is "sound used as entertainment" or something like that, "pleasing sound" could also do. But that is wrong. Music is sound ordered in terms of harmony, melody and rhythm. Concepts like harmony, melody and ryhthm can be explained by phyics. What does this mean? This means that sound ordered is more musican than sound not ordered. This means music which is very much ordered is more musical than music that isn't.The comment of lostinidlewonder comes in here. The fact that it is ordered doesn't mean it needs to be ordered in a very logical or natural way. Something can be ordered in a chaotic way. When lostinidlewonder talks about "the control of volume and tempo" then that means that a musical piece that has some plan, variation, structure or order in terms of volume is more musical than a piece that doesn't have that. If the composer or performer gave thought to this and worked it in his art is has more musical elements then when the piece has a monotome volume.Same goes for tempo, for chords, for melody, for sound quality, for anything.
