It has occurred to me on a number of occasions that perhaps the advent of the Internet, iTunes and mass media in general has changed the face of folk music for ever. By this I mean that in centuries gone by, music such as folk would somehow be seeded by a great idea and move from village to village, region to region by listening and copying. This lead, as has been mentioned frequently elsewhere in this forum, to folk tunes evolving and changing and somehow growing stronger with a sort of natural selection taking place. My fear is that with mass media all around us, this mechanism is now blocked. A new folk tune, once created, becomes fixed by YouTube so to speak. Any thoughts on this?
