reverberation

If, having fixed the original form in our mind's eye, we ask ourselves how that form comes alive and fills with life, we discover a new dynamic and vital category, a new property of the universe: reverberation (retentir). It is as though a well-spring existed in a sealed vase and its waves, repeatedly echoing against the sides of this vase, filled it with their sonority. Or again, it's as though the sound of a hunting horn, reverberating everywhere through its echo, made the tiniest leaf, the tiniest wisp of moss shudder in a common movement and transformed the whole forest, filling it to its limits, into a vibrating, sonorous world.
