Liscio
Also called ballo liscio, Romagnolo liscio
Northern Italian accordion ballroom, especially Romagna: waltz, polka, mazurka (and later tango) for the balera. It is a genre, not a leftover “Italian folk” bin. It hears those three dance forms, plus Musette as accordion-bal grammar and Tango as a later floor item. It is a job-sibling of musette, not its child in taxonomy. Empty Given is historically checked. Italian folk leftover as a refused catch-all. Alpine yodel leftover as already refused.
