Random Thot: what's the difference between Harmony and Equality?

Harmony : pleasing or congruent arrangement of parts
Equality : the quality or state of being equal.

So what's the diff between racial harmony and equality. Someone said to have harmony there must be equality. I tend to disagree with that. I believe that Equality can only come if there is harmony.

If Harmony as defined by the dictionary is a "pleasing and congruent arrangement of parts" then those parts need not be equal in state, stature, size or standing. Harmony is then a choice made to get along others regardless if the parts are equal.
