Karen Tuttle (March 28, 1920 – December 16, 2010) was an American viola teacher, famous for her "coordination" technique, which emphasizes being comfortable while playing the instrument.
She was originally a violinist who chose to become a violist when she wanted to study with William Primrose, whose technique and ease in playing the viola she greatly admired.
Her coordination technique is often considered to be an analysis of Primrose's technique.
She was a frequent participant at the Marlboro Music Festival in Vermont.
In 1955, she was invited by Pablo Casals to perform chamber music with him at the Pablo Casals Festival in Prades, where she returned for at least seven subsequent festivals.
She made her Carnegie Hall recital debut in February 1960.
Her recital was reviewed by Harold Schonberg, a leading reviewer for the New York Times.
He wrote, "About as large an audience as Carnegie Recital Hall has ever held jammed it yesterday evening at 5:30 to hear Karen Tuttle's recital.
The violist, with Artur Balsam at the piano, gave a concert that seemed to be attended by every string player in town.".She was a member of the Galimir, Gotham, and Schneider Quartets, as well as the American String Trio.
In 1994 she was recognized by ASTA with the Artist Teacher Award.
