"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:
... It fascinates me that such a trifling tune could have settled into the public consciousness as Ja-Da has. Of course it's bone simple, and the lyric says almost nothing, except perhaps the explanation of its success lies in the lyric itself. "That's a funny little bit of melody—it's soothing and appealing to me." It's cute, it's innocent, and it's "soothing." And, wonderfully enough, the only other statement the lyric makes is "Ja-Da, Ja-Da, Ja-Da, Ja-Da, Jing, Jing, Jing."[1]
