Bark trumpets have been and are used the world over, but this Colombian trumpet is again an example of instruments serving a function outside of performance, as they are often used for relaying information over long distances. The reed on the other hand can only be used as part of a larger instrument, though that instrument itself may have had multiple functions; nevertheless, it serves as a strong example of the utilization of a similar material to the trumpet, but for an entirely different purpose. For more information regarding pan pipes and their various functions, see the objects under the Friedlaender Collection page.
