Mark Pentecost of Anglicare runs a music program for Anglicare residents using acapella ensembles. He explained this on TV that it touches the deepest parts of the psyche, important for people with dementia, becuase it harks back to a time before there were musical instruments.
This refers possibly to a narrow slice of early history, because we read in Genesis 4:21 of "Jubal; he was the father of all those who play the lyre and pipe."
There in the fourth generation of humanity two musical instruments were known! OK, so the previous three generations just hummed, but I wouldn't think that acapella has a greater musical connection with us than a brass band. Its just that most Anglicans have shelved the early history of God's creation and have absorbed and therefore defer to the world-starts-with-material game.
