This is not a brook [Bach means "brook" in German], it's an ocean.

It is the power of music to carry one directly into the mental state of the composer.

ever thine, ever mine, ever ours

We mortals with immortal minds are only born for sufferings and joys, and one could almost say that the most excellent receive joy through sufferings.

Wherever you are, I am there also.

From the glow of enthusiasm I let the melody escape. I pursue it. Breathless I catch up with it. It flies again, it disappears, it plunges into a chaos of diverse emotions. I catch it again, I seize it, I embrace it with delight... I multiply it by modulations, and at last I triumph in the first theme. There is the whole symphony.

He that divines the secret of my music is freed from the unhappiness that haunts the whole world of men.
