These unique instruments, or shamanic tools as we will later discuss, are called whistling vessels or otherwise known in Spanish as huaco silbadors. Most of the original vessels are estimated to have been made around 500 BC – 1200 AD, and a majority of them have been found in Peru.
This article will discuss the origin of these intriguing pieces, what they were used for, how they work and the future of whistling vessels.
Since first laying eyes on these instruments in a YouTube video many years ago, I have been slightly obsessed with them. These beautiful art pieces, which can be found in many museums, are usually unique in exterior design, but fairly similar with functional construction of the mechanisms for producing sound.
