But the people here obviously do care and have an interest in what you are trying to do.

Even when using English you are far from clear. 'relevant ideas and terms'. What are you trying to say, in plain words please? Gibb and others have set out what boundaries are possible and have descriptions of chanties from the early 1800s onwards up to when these songs were being used in the Gulf ports 1n the 1830s and their transference to shipboard. Influences from other genres. Up to when the term chanty was being used aboard ship. Plenty of contemporary references. What more do you want? I know Gibb is interested in what happened to the chanties once the English anthologists got hold of them and started making up bowdlerised texts, but I'm more interested in the contemporary history.
