In 1988, the ninety-two-year-old Ornstein wrote his Seventh Piano Sonata. With this composition Ornstein became, by a couple of years, the oldest published composer, until Elliott Carter, ever to produce a substantial new work. On September 23, 1990, at the age of ninety-four, Ornstein completed his final work, the Eighth Piano Sonata. The names of the sonata's movements reflect not only the passage of a remarkable span of time, but an undimmed sense of humor and exploratory spirit: I. "Life's Turmoil and a Few Bits of Satire" / II. "A Trip to the Attic—A Tear or Two for a Childhood Forever Gone" (a. "The Bugler" / b. "A Lament for a Lost Toy" / c. "A Half-Mutilated Cradle—Berceuse" / d. "First Carousel Ride and Sounds of a Hurdy-Gurdy") / III. "Disciplines and Improvisations." Reviewing the work's New York debut, critic Anthony Tommasini wrote, "Between the roaring craziness of the first and third movements, the middle movement is a suite of four short musical musings on childhood mementos discovered in an attic. Though completely incongruous, the shift in tone is audacious and the music disarming. The audience listened raptly, then erupted in applause."
