More R.N. thread drift.
Steve: I seem to be missing something here. Has the word 'chanty' however you spell it ever been used anywhere in a historical context to describe anything other than work SONG aboard merchant ships? Nothing personal about it as far as I can see. Your persistent desire to include other things under the term is commendable, but we would like to see some evidence.

Advent & Development thread: Please note that the focus here is not on the ancient origins of work-songs, shipboard or otherwise. It is not on the origins or earliest references to singing/chanting to coordinate labour at sea. [Gibb]

Whereas, please note that the focus here is on the origins of work-songs, shipboard or otherwise. It is on the references to singing/chanting to coordinate labour at sea;… to which I will add... ancient, early or late but in some semblance of chronological order, hopefully.

Where any one citation fits homework assignment, songbook or record shelf is up to the individual consumer.

For the record Steve. I do not know what a “chantey” is until I've learned: who is using the label; on what product and in what marketplace. Change any one of the three and the definition will change accordingly. I would think you have your genre/sub-genre backwards. Chantey is filed under celeusma not the other way around, but that's just me.
