Bagpipe \Bag"pipe\, n.
   A musical wind instrument, now used chiefly in the Highlands
   of Scotland.

   Note: It consists of a leather bag, which receives the air by
         a tube that is stopped by a valve; and three sounding
         pipes, into which the air is pressed by the performer.
         Two of these pipes produce fixed tones, namely, the
         bass, or key tone, and its fifth, and form together
         what is called the drone; the third, or chanter, gives
         the melody.

Bagpipe \Bag"pipe\, v. t.
   To make to look like a bagpipe.

   {To bagpipe the mizzen} (Naut.), to lay it aback by bringing
      the sheet to the mizzen rigging. --Totten.
