The current Dutch alias for the friction drum (rommelpot / foekepot) is actually two synonyms. Could you change the alias to “rommelpot” and add an extra Dutch alias for “foekepot”?

By the way, Wikipedia/-data treats the rommelpot as a different instrument from the friction drum. That’s a bit silly because it’s a general concept rather than a standardised instrument (almost all are home-made). The Wikidata link for rommelpot is https://www.wikidata.org/wiki/Q9097454. Perhaps it could be added to the instrument?
