    What length would a tube (conch shell) need to be to produce the E above middle C?

    Calculated it, cut a bit of tube, play tested it. About 10 inches.

    Thanks. I've been demonstrating blowing a conch shell in class, and the question came up. The class is a high school literature class studying "Lord of the Flies".

    Yes, the conch is an important part of the story. The unrealistic part is that they found a conch and started blowing it, without cutting the end off and making it a trumpet. Literary license, I guess.

    Tube resonant frequency is based on length, irregular shapes on volume (fill various sized bottles with water until the pitch matches) horn contours follow horn theory. With a conch shell, I believe the volume is most significant. You can fill it with resin, play test and create a whole scale!

    It's not totally out of the question that while the thing was rotting out and rolling around in the surf it got knocked against something and broke off the tip. After all, the very first conch that was played probably wasn't by some guy taking his hacksaw for a walk on the beach...
