Charles Wadsworth, Pianist and Champion of Chamber Music, Dies at 96

Charles Wadsworth, a pianist who parlayed his Southern charm and his passion for chamber music into a career as the founder, director and host of important chamber series — including the Chamber Music Society of Lincoln Center in New York — and whose work helped propel the chamber music boom that began in the 1970s, died on Thursday in Manhattan. He was 96.

His death, at a rehabilitation center, was confirmed by his wife, Susan.

During his two decades as director of the Chamber Music Society, Mr. Wadsworth was the face of the organization, likely at any time to stride onto the stage of Alice Tully Hall with a broad grin, tousled blond hair and a boyish gait and offer folksy introductions to the music at hand.

“I discovered very early that when people laugh, they relax,” Mr. Wadsworth told an interviewer in 2014. “They may be at a chamber music concert for the first time, or they may be unfamiliar with the repertory, but my feeling was that if I could get them relaxed, they would be open to listening, and to letting the music happen to them, rather than worrying about whether they understand it. And that seemed to work very well.”

He also performed with the society, playing the piano, harpsichord or even the organ in staples of its repertory as well as some of the oddities he found while assembling the society’s programs — works like Anton Arensky’s Suite No. 1 for Two Pianos, François Couperin’s “Le Parnasse, ou L’Apothéose de Corelli” or Jan Zelenka’s Trio Sonata for Two Oboes, Bassoon and Continuo. But since the society’s roster included pianists who by Mr. Wadsworth’s own admission were more accomplished, he often deferred to them.

His real accomplishments took place behind the scenes. Not least was the creation of the society itself, an organization meant to explore the breadth of the chamber music repertory, regardless of the instrumental (or vocal) combinations required. Mr. Wadsworth assembled a core group of “artist members” — string, wind and keyboard players with active careers, who would commit to performing with the society throughout the season — alongside guest musicians, who would expand the instrumental possibilities and bring an extra measure of star power.
