"Que Pasa" is a hard bop composition by Horace Silver, featured on his landmark album Song for My Father (Blue Note, 1965). The tune exists in two recorded versions from the album sessions: a quintet version recorded in 1964 with Carmell Jones on trumpet, Joe Henderson on tenor saxophone, Teddy Smith on bass, and Roger Humphries on drums, and an earlier trio version from October 31, 1963, with Gene Taylor on bass and Roy Brooks on drums, which appeared as a bonus track on later CD reissues. Described as having a Spanish lilt, the composition reflects Silver's lifelong interest in Latin-inflected rhythms and global musical flavors, filtered through his signature hard bop sensibility. The melody is characteristically catchy and horn-friendly, built over harmonies that support intriguing improvisational exploration. The quintet version runs nearly eight minutes, giving the soloists generous space to develop their ideas over Silver's changes. Song for My Father drew broadly from Silver's Cape Verdean heritage and a formative trip to Brazil, and while "Que Pasa" is not explicitly tied to those biographical threads, its Latin character fits naturally within the album's cross-cultural aesthetic. The tune remains a deep cut in Silver's catalog rather than a frequently performed standard, overshadowed by the album's iconic title track but valued by listeners familiar with the full record.
