(Psalms 133 NIV) 
Behold, how good and how pleasant it is for brethren to dwell together in unity !

Harmony is not the same as unity, for if you mix all the colours of the rainbow together you end up with brown. Similarly, if you mix all the musical instrument and notes together you end up with an unpleasant cacophony of sound.

Harmony requires that things work together in unity and don’t interfere with one another or cancel one another out.

Where two or more things work together in perfect harmony, there is no friction and no wasted energy.

When heaven and earth work in harmony - life is at peace.

A big bang would bring only chaos and it denies any underlying cause behind all bangs, change and evolution.

The so called ‘atom’ is a marvellous, mystical and magical fractal of the infinity that is our reality… just stop and think for a moment about what we imagine is going on inside an atom and then ask yourself this question… how does it all stay together and not fly apart?

A rainbow is a perfect illustration of this, it is a product of different frequencies working together side by side to create something magical and beautiful to behold.
Harmony and Beauty are sisters and though it is true that beauty is in the mind of the beholder - there is a world of difference between a convoy of trucks rumbling down the street and an orchestra playing a single piece of music together.

Love is that invisible cause that brings order from chaos, it strives for perfect balance and peace - it seeks that all things work together for good. Without love there can be no harmony or beauty, only chaos, injustice and the noise of friction.
An orchestra without a conductor or operating from a single sheet of music or common standards of musical behaviour would sound like a terrible jazz band and an atom without some underlying unifying agency would dissolve into chaos.
There are natural limits to how many frequencies one can fit in 3D space harmonically - which is probably why the largest atomic structures tend to be radioactive and throw off what cannot be contained in a stable and ordered way.

(Matthew 18:20 NIV) 
For where two or three are gathered together in my name, there am I in the midst of them.
