Jonathan Tunick Unveils a Grand Orchestration of Sondheim’s ‘A Little Night Music’

Near the end of Stephen Sondheim’s musical “A Little Night Music,” the orchestra swells to what he is said to have called his Max Steiner moment, something out of “Casablanca” or “Gone With the Wind.”

Désirée and Fredrik, former lovers who reconnect but nearly miss out on happiness again, come together and kiss. The instruments respond with a grand, emotive reprise of the show’s 11 o’clock number, “Send in the Clowns.”

At a concert performance of “A Little Night Music” at David Geffen Hall on Thursday, the premiere of a new orchestration by Sondheim’s longtime collaborator Jonathan Tunick, the 53-piece Orchestra of St. Luke’s let out a fortissimo tutti. Strings and winds soared with the melody, but there was more: resonant, staggered chords to support it in the low voices, and florid counterpoint. It was a moment fit not only for the movies but for the opera house, which, perhaps, is where this new orchestration belongs.

Not all musicals are fit for stages beyond Broadway, but some are. And there has been a resurgence, since Sondheim’s death in 2021, of large-scale revivals of his work. (This, after years of skillfully stripped-down productions by John Doyle.) “Sweeney Todd” returned to Broadway with Tunick’s original orchestration for nearly 30 players, crackling with detail and musical drama. Last week, “Follies” was presented at Carnegie Hall with a similarly sized ensemble and a starry cast in concert.

The version of “A Little Night Music” on Thursday had nearly double those forces. If anyone can be trusted with that task, it’s Tunick. He and Sondheim first collaborated on “Company,” in 1970, and Tunick orchestrated the composer’s final, unfinished show, “Here We Are,” last year.
