Other forms: hootenannies
A hootenanny is a lively folk music party or performance. If you're invited to a hootenanny, bring your fiddle or come prepared to sing along!
When hootenanny first appeared in American English, it was an informal word for "gadget," a generic placeholder like thingamajig or doodad. It came to mean "impromptu party with music" in some rural regions and was adopted in the 1940s for gatherings held by folk musicians including Woody Guthrie and Pete Seeger. Hootenannies reached the height of popularity in the 1960s, but you can throw one today by getting together with friends to play and sing music!
