Question: are y'all positing that the shift from dugout/early boat to sails and requiring a crew brought a *qualitative* change in the worksongs sung? That actually might make sense, given the class distinction between crew and officers which was likely absent in canoes. The dugout folks would certainly have had seafaring work songs. Which we don't call chanteys for a reason which escapes me (2nd question).
I am thoroughly enjoying this thread. Thanks, refresher.
