Which word describes the tone produced when a clenched hand strikes a Boatswain's pipe?

• A. Deep Bellow
• B. Soft Whisper
• C. Shrill
• D. Rumble

Answer: (C)

The key idea here is how a percussive impulse affects the tone of a wind signaling instrument. When you strike a Boatswain’s pipe with a clenched hand, you slam the air column inside the pipe, creating a sudden, sharp impulse. This excites higher frequencies and quick, bright overtones, so the resulting sound is piercing and high-pitched—what we describe as shrill.

Think of it like this: a quick kick to the air column tends to emphasize the upper end of the frequency spectrum, producing a tone that cuts through noise rather than a deep, mellow sound. The other options describe lower, softer, or more muted sounds that don’t match the rapid, high-frequency response produced by a hard, instantaneous strike.
