Things You'll Need
Instructions
Hold the boatswain's call firmly between your thumb and index finger. Curl your other fingers gently around it, taking care not to block the hole.
Place the mouthpiece gently between your lips. Blow firmly into the mouthpiece. This produces a low note.
Close your fingers tightly around the rounded lower part of the whistle, called the buoy. This produces a high note.
Trill and warble by moving your tongue inside your mouth as you blow on the call. To trill, roll your tongue against the roof of your mouth as if you were rolling an "R" sound. To warble, move the tongue back and forth across the mouthpiece while alternating between low and high notes.
Play the pipe by alternating low and high notes in the correct patterns. Each pipe has a unique pattern that will be instantly recognizable to the hands on board.
