"Let's Fall in Love" opens the 1957 Verve album Getz Meets Mulligan in Hi-Fi with a performance that establishes the session's unique concept: Gerry Mulligan playing tenor saxophone and Stan Getz playing baritone, each stepping outside his primary instrument. Mulligan's two-chorus tenor solo over the 32-bar AABA form in F major at 151 beats per minute demonstrates that his musical intelligence transcended any single horn, his phrasing on the unfamiliar instrument retaining its characteristic melodic grace. Getz, on baritone, brings his legendary lightness of touch to the larger horn, his two choruses revealing a different tonal dimension while maintaining the lyrical fluency that defined his artistry. Harold Arlen's 1933 composition provides a bright, accessible framework for the instrumental swap. The rhythm section of Lou Levy on piano, Ray Brown on bass, and Stan Levey on drums provides swinging support throughout. Produced by Norman Granz for Verve, the album's concept of having two of the era's most distinctive saxophonists trade instruments was both a creative gambit and a demonstration of fundamental musicianship, proving that great jazz artists are defined by their musical conception rather than the specific horn they happen to hold.
