“Aside from recurrence, revision, and commensurate symbolic reference, echoes also reveal emptiness. Since objects always muffle or impede acoustic reflection, only empty places can create echoes of lasting clarity. Ironically, hollowness only increases the eerie quality of otherness inherent in any echo. Delay and fragmented repetition create a sense of another inhabiting a necessarily deserted place. Strange then how something so uncanny and outside of the self, even ghostly as some have suggested, can at the same time also contain a resilient comfort: the assurance that even if it is imaginary and at best the product of a wall, there is still something else out there, something to stake out in the face of nothingness.... It is not by accident that choirs singing Psalms are most always recorded with ample reverb. Divinity seems defined by echo. Whether the Vienna Boys Choir or monks chanting away on some chart climbing CD, the hallowed always seems to abide in the province of the hollow. The reason for this is not too complex. An echo, while implying an enormity of a space, at the same time also defines it, limits it, and even temporarily inhabits it. When a pebble falls down a well, it is gratifying to hear the eventual plunk. If, however, the pebble only slips into darkness and vanishes without a sound, the effect is disquieting. In the case of a verbal echo, the spoken word acts as the pebble and the subsequent repetition serves as ‘the plunk.’ In this way, speaking can result in a form of ‘seeing.’”
