Algolian musical instrument

The Algolian musical instrument was a large instrument consisting of many small chimes that were struck with small wooden hammers and played according to certain ceremonial rhythms.

An Algolian musician was aboard the USS Enterprise (NCC-1701-D) during the biennial Trade Agreements Conference and entertained the visitors of Ten Forward by playing his instrument.

William T. Riker later transmitted the rhythm by subspace as a covert distress signal from the Ferengi Marauder Krayton whose crew had kidnapped him, Deanna and Lwaxana Troi.
