Quote from : Cold Mountain Book

Ruby said there were many songs that you could not say anybody in particular had made by himself. A song went around from fiddler to fiddler and each one added something and took something away so that in time the song became a different thing from what it had been, barely recognizable in either tune or lyric. But you could not say the song had been improved, for as was true of all human effort, there was never advancement. Everything added meant something lost, and about as often as not the thing lost was preferable to the thing gained, so that over time we'd be lucky if we just broke even. Any thought otherwise was empty pride.
