Mentioned by Amazon in the introductory text to Paige Shelton [-Ferrell]: »Of books and bagpipes«: A Scottish bookshop mystery (New York, 2017 [LLC, Wiki Series]); NB [¹]: Wikipedia describes it as "a type of bagpipe designed and crafted in the 1990s by Pipe Major Royce Lerwick, who believed that the bagpipes had been introduced to the British Isles by the Vikings. His "Zetland pipes" were intended to resemble single-drone, single-reeded pipes such as might have been brought to the Shetland Islands by the Vikings. The term "Zetland" is an antiquated variant of "Shetland". NB [²]: According to Lerwick, the original impetus for the design was the Lady Maket pipes, or Silver Pipes of Ur. This was an archaeological find, resembling bagpipes [sic], dating back to 2500 BCE. [1]: ➺ Bo Lawergren, "Extant silver pipes from Ur, ca. 2450 BC"; NB (plurale tantum): The term is also used when referring to 1 instrument only.
