Bosun's Call

The use of the bosun's call goes back to the 13th century when it was introduced to pass messages on a ship. Using a whistle meant that messages could be heard even in the strongest of winds. The bosun's call was used as a badge of rank as it was a means of giving orders.

Today the bosun's call is officially the 'boatswain's call' and it is used alongside more sophisticated means of communication by the Royal Navy as they are great believers in tradition. The bosun's call is also used by Sea Scout Troops across the world.

The Bosun's Call is attached to a rope lanyard (metal chain for the Royal Navy) and worn as part of uniform.


Piping
The call should be held between the index finger and thumb, with the thumb on or near the shackle The side of the buoy rests against the palm of the hand and the fingers close over the gun and buoy hole in position to throttle the exit of air from the buoy to the desired amount. Care should be taken not to touch the hole of the buoy or the end of the gun, or the sound will be choked.

There are two main notes; the low and the high, and three tones; the plain, the warble and the trill.

The low note is produced by blowing steadily into the mouth of the gun with the hole of the buoy unobstructed by the fingers.

The high note is produced by throttling the exit of air from the hole of the buoy. This is done by closing the fingers around the buoy, taking care not to touch the edge of the hole or the end of the gun.

The warble is produced by blowing a series of jerks, which results in a warble similar to that of a canary.

The trill is produced by vibrating the tongue while blowing, as in rolling the letter R. Back to top
