"Make Sure You're Sure" is a ballad composed by Stevie Wonder for the soundtrack to Spike Lee's 1991 film Jungle Fever. The composition is set in a 34-bar AABA form, a slight departure from the standard 32-bar structure that gives the piece a distinctive sense of pacing. The melody is hauntingly lyrical, blending uncertainty and tenderness as it evokes the feeling of cautiously falling in love, supported by lush string arrangements and Wonder's characteristic harmonic sophistication drawn from his command of pop, R&B, and jazz vocabularies. The tune's opening sets a nocturnal, starlit mood that unfolds through a push-pull dynamic of vulnerability and romantic intensity, making it well suited to intimate performance settings. Wonder composed nearly all of the Jungle Fever soundtrack, and "Make Sure You're Sure" stands as one of its most quietly affecting moments, distinguished by its jazz-inflected harmonic language and ballad sensibility. While overshadowed by more prominent Wonder compositions, the tune has attracted attention from jazz musicians drawn to its rich chord changes and emotional depth. Joshua Redman included a notable instrumental interpretation on his 1993 album Wish, reimagining it for tenor saxophone and guitar in a quartet setting that highlighted the composition's adaptability beyond its original vocal context. The piece has also been arranged for big band, further demonstrating its appeal as source material for jazz reinterpretation. It remains a deep cut in Wonder's extensive catalog rather than a widely covered standard.
