I really like the wailing wall idea.
The Native Americans used to go off in nature by themselves and sing certain songs and Native chants to cope with grief and pain and life changes. I think some of that stuff got handed down to the Appalachian people, many of who intermixed with the Cherokee. Here is a song by Ralph Stanley....it is very haunting....but it reminds of a "death song" someone might sing or chant as they are nearing death. I took care of a Native woman once on her death bed and she sang the Death Prayer. This reminded me a bit of it in some distant echo of time.....

I hope this isn't too morbid.
