Triathlon has a duration of roughly 30 minutes and is cast in three movements that each call for a different instrument in the saxophone family:
Leaps (soprano saxophone)
Lines (alto saxophone)
Licks (baritone saxophone)
The movement titles correspond to different facets of the music. "Leaps" refers to wide intervals of the opening theme. In the score program note, Corigliano wrote, "This melody utilizes the entire lyrical range of the soprano saxophone, and leads to a slower section that extends and develops the melody. But the joyous opening returns and the movement ends as it began — with a leap." The title of the second movement "Lines" refers the horizontal motion of its melody. The final movement "Licks" is named for the eponymous musical term, which refers to small improvisational moments in jazz. The composer added, "While this is not a jazz movement, the idea of small ornamental turns appealed to me, and provided me with the inspiration for the solo writing."[1]
Reviewing the world premiere, the music critic Joshua Kosman of the San Francisco Chronicle praised Triathlon, writing, "As the title suggests, it's a workout." He continued, "Corigliano’s 30-minute extravaganza, which the [San Francisco] Symphony had originally commissioned for a 2020 premiere that was delayed by the COVID pandemic, was the highlight of Thursday's matinee program. It grabbed a listener's attention from the first notes, and lingered long in the memory after everything else had passed."[3]
