She was born as Sofia (Sonia) Fri[e]dman-Kochevskaya in Moscow, where her mother worked as a governess in the Tolstoy household.[3] She began to learn piano in 1904 and wrote her first piano compositions in 1905. She studied at the Conservatoire de Paris from 1908 to 1913, where her teachers included Alfred Brun and Guillaume Rémy for violin, S. Chenée for piano, and Vincent d'Indy and Camille Chevillard for composition. She made her début in 1910, and her first composition, an Etude de Concert, was published in Paris that year. She moved to Berlin in 1914, where she studied violin with Bronisław Huberman; by 1919 she had undertaken several concert tours of Western Europe, on which she performed her own works.
In 1920, she married the painter Walter GramattéinBerlin, and from 1924 to 1926 lived in Spain, where Pablo Casals was her mentor. During this time she wrote her first piano concerto. She toured with Edwin Fischer in Germany in 1925.[4]
Following her husband's death in 1929, she toured the US, performing to critical acclaim her first piano and violin concertos in an American debut with Leopold Stokowski in Philadelphia and Frederick Stock in Chicago. Upon her return to Berlin in 1930 she gave up her performing career to devote herself to composition.
In 1934, she married the journalist and art historian Ferdinand Eckhardt. From 1936 she pursued further lessons in composition with Max Trapp in Berlin at the Berlin Academy of Arts. She and her husband moved to Vienna in 1939 where she continued to compose. In 1945 she became a member of the group that reopened the Austrian branch of the International Society for Contemporary Music. The couple left Vienna in 1953, and settled in Winnipeg, Canada, where she continued to compose. In Winnipeg she taught several violin students out of a private studio, including violinist Gwen Thompson.
In 1970 she was awarded an honorary doctorate from Brandon University, Manitoba, as well as the title 'professor' by the Viennese minister of education. In 1974 she became the first Canadian composer to receive the Diplôme d’honneur of the Canadian Conference of the Arts. Also that year her life was the subject of a two-hour CBC documentary. Some of her music and old performances are included in Radio Canada International's Anthology of Canadian Music. A project that she had initiated to encourage young musicians to study and play contemporary music was only realised posthumously in 1976, with the first annual Eckhardt-Gramatté competition for the performance of Canadian music.
Eckhardt-Gramatté died in Stuttgart as a result of an accident. Her legacy is preserved through the work of the Eckhardt-Gramatté Foundation.
As a composer Eckhardt-Gramatté was largely self-taught. She composed more than 175 works. She learned a great deal from the virtuoso music she performed on both the piano and the violin, and her compositions – especially from the 1920s – reflect this. By the late 1930s her contrapuntal idiom had reached full maturity, and in the following decade her style moved towards neo-classicism and bitonality with some use of jazz idioms. In 1950, with the Piano Sonata no.5, she began to adopt serialism, and by 1955 her use of metric manipulation showed similarities to that of Olivier Messiaen and Boris Blacher. She retained a lifelong admiration for the music of Johann Sebastian Bach – the ending of her 1955 Concerto for Orchestra reworks the prelude from his Partita in E major – and, like Bela Bartók, she frequently used the interval of a fourth as a structural device. Her music is dark, dense and dramatic, with forward drive. She admired the First Viennese School, but her brand of counterpoint is individual and its dissonance owes much to the post-Romantics. Despite her use of modern techniques, she remained a Romantic in spirit. In addition to writing music, she developed a piano teaching method, the 'E-gré Piano Technique', whose basis is the use of rotary movement.
