before and after follow each other

The title before and after follow each other, refers to the inspiration for this piece in addition to its structural conception; the music is a meditation on mortality and is primarily through-composed. These words, a phrase from the Tao Te Ching, suggest that when the distinction between life and death is abolished, death is no longer something to be feared.

Thus Something and Nothing produce each other;
The difficult and the easy complement each other;
The long and the short off-set each other;
The high and the low incline towards each other;
Note and sound harmonise with each other;
Before and after follow each other.
