Not disagreeing in any significant way, at all. I thought about "communal" for a while, since mention of "work songs" in several threads brought to mind Waulking Songs, with a solo line given out by one singer followed by all the other women. There are certainly old B&W newsreels of Hebridean women at this work. The word is, I thought, sufficiently broad to cover that "choral" sense as well as implying songs known in a community. Not intending to set up or challenge definitions or anything, just intrigued by the different kinds of "atmosphere" encountered in different discussions despite there being some similarities with regard to materials and ideas, in my view at least. Good Luck. ABCD.
