Helena Norbert-Hodge tells the story of the people of Ladakh (mountain country near Tibet) where she was an anthropologist in the 1950's. Everyone sang all the time, and while everyone recognised good singers, they knew that the good singers were bad yak herders, or whatever. Then the radio arrived: the distillation of excellent specialised singing from everywhere beamed at them. From that moment, bad singers and good singers alike became ashamed of how they sounded, and the best singers began to emulated the voices on the radio, and lost their originality. Group singing became a thing of the past, or something hidden away, or focussed on the one good singer doing a performance. The non-professionals had now become a permanent audience, and not just people who were better or worse singers than everyone else, but still singers.

No moral: just worth contemplating.
