"Ja-Da (Ja Da, Ja Da, Jing, Jing, Jing!)" is a hit song written in 1918 by Bob Carleton. The title is sometimes rendered simply as "Jada." The song has flourished through the decades as a jazz standard.
In his definitive American Popular Songs, Alec Wilder writes about the song's simplicity:
In Jack Finney's 1995 novel From Time to Time, the time-traveling protagonist recalls a childhood memory of his aunt dressing up in her old flapper costume and dancing the Charleston to "Ja-Da," singing its playful refrain "Jotta, jotta, jink-jink-jing." <nowiki>[</nowiki>sic<nowiki>]</nowiki> He associates the tune with a stylish young woman he meets in 1912, whom he calls "the Jotta Girl," a character who later becomes central to the novelâÂÂs plot. (The reference is anachronistic, as "Ja-Da" was not composed until 1918.)
