Eefing

Eefing (also written eeephing, eephing, eeefing, eefin, or eefn') is an Appalachian (United States) vocal technique similar to beatboxing, but nearly a century older. NPR's Jennifer Sharpe describes it as "a kind of hiccupping, rhythmic wheeze that started in rural Tennessee more than 100 years ago."

An eefing piece called "Swamp Root" was one of the first singles recorded and released by Sam Phillips. Singer Joe Perkins had a minor 1963 hit, "Little Eeefin' Annie" (#76 on the Billboard chart), featuring eefer Jimmy Riddle, whom Sharpe calls "the acknowledged master of the genre". Riddle later brought eefing to national visibility on the television series Hee Haw.
