What does piping mean in this fragment from Treasure Island by Stevenson?
...And I was going to sea myself, to sea in a schooner, with a piping boatswain and pig-tailed singing seamen, to sea, bound for an unknown island, and to seek for buried treasure!... (Ch. 7)
Does the boatswain have a pipe or is he a specialist in pipelines?
It means playing a pipe. To be more accurate, a bo'sun's whistle. You may have seen (or heard) them in films when a senior officer is being "piped" aboard a warship.
