Marta Kurtag, a pianist and teacher who shared a 72-year collaboration with her husband, the prominent avant-garde composer Gyorgy Kurtag, profoundly influencing his work and joining him in dual recitals, died Oct. 17 in Budapest. She was 92.

She played a pivotal role in Hungarian musical life as a piano teacher — first at the Bela Bartok College of Music in Budapest, from 1953 to 1963, and then, after 1972, on the faculty of the Franz Liszt Academy of Music, Hungary’s storied conservatory from which she had graduated in 1952. A pianist of considerable skill and insight, she had a solo career of her own in Eastern Europe.

Of the joint piano recitals, Alex Ross of The New Yorker wrote, “You felt that you were eavesdropping on an intimate family affair. Like some sweet old couple in a movie, the Kurtags smiled at each other and allowed their bodies to sway with the music, apparently oblivious of the packed hall of new-music aficionados watching them.”

At risk after WWII had broken out, Jews faced increasing repression in Hungary. Her father urged her to flee. With forged papers and the help of a Zionist group, she crossed into Romania. Left behind, her parents and her brother perished.
