Airegin is an original composition by tenor saxophonist Sonny Rollins, first recorded on June 29, 1954, at a Prestige Records session led by Miles Davis. The title is Nigeria spelled backwards, a tribute inspired by a magazine photograph of Nigerian dancers that had impressed Rollins. He brought three new compositions to that session, including Oleo and Doxy, and all three quickly became jazz standards. The melody is angular and propulsive, built over a sophisticated harmonic progression that features a series of deceptive resolutions, where ii-V chord patterns set up movement toward one key but resolve unexpectedly elsewhere. This quality gives the tune a sense of constant harmonic motion and unpredictability that rewards attentive improvisation. Rollins reportedly had not fully completed the compositions when he arrived at the studio, writing out parts on scraps of paper during the session itself. Despite these informal origins, the tune became one of the most durable vehicles in the hard bop repertoire, recorded by artists spanning a wide range of styles. Miles Davis revisited it with his classic quintet featuring John Coltrane for the 1956 album Cookin'. Wes Montgomery recorded a celebrated guitar version on The Incredible Jazz Guitar of Wes Montgomery in 1960. Jon Hendricks later composed lyrics depicting Nigerian history, performed by Lambert, Hendricks and Ross and subsequently by Manhattan Transfer. The composition remains a staple of jazz performance and a rite of passage for improvisers navigating its harmonic challenges.
