“MOM!” the pianist says with some concern as he launches into their favorite song, “Somewhere Over the Rainbow,” and a photographer begins to click away. “You can’t cry on camera.”

Though not usually with a photographer in tow, composer David Conte often drops by the Carlisle, the retirement community at 1450 Post, to visit his mother, Carlisle resident Nancy Conte. He often plays her favorite classics or show tunes before or after he goes to work at the San Francisco Conservatory of Music, where he is a professor of composition and head of the composition department. Other Carlisle residents are treated to regular impromptu mini-concerts.

Performing and composing are nothing new for David Conte. At 7, he and a friend wrote songs and gave concerts in their suburban Cleveland neighborhood. Music education in the public schools was at its zenith, and his father played the trumpet. By 8, he had started piano lessons, and by the time he reached 13, he knew music would be his life. At 19, he moved to Paris for three years, where he became one of the last pupils of world-renowned teacher Nadia Boulanger.

Conte, the eldest of his mother’s three children, has composed more than 100 published works, including six operas and works for orchestra, chamber groups and chorus. His work has drawn critical praise, and aspiring composers arrive at the conservatory to study with him.

But to Nancy Conte — herself a former choral conductor and an encyclopedia of musical texts and tunes — he’s still the son she started driving to piano lessons back in Ohio when he was 8 years old. “It was a lot of schlepping around for a lot of years,” she says. Her son smiles as he launches into a Schubert sonata and says: “Don’t you think I owe her?”
