Her performances were recognized by the public and local newspapers; the Revue et gazette musicale printed a review on July 27, 1862, that reads: "She marked it [the piece] with the seal of her individual nature.
Her higher mechanism, her beautiful style, her play deliciously moderate, with an irreproachable purity, an exquisite taste, a lofty elegance, constantly filled the audience with wonder.
"[7] On August 9, 1866, at twenty years of age, Marie married the Austrian concert pianist Alfred Jaëll.
[citation needed] The husband and wife team performed popular pieces, duos, solos, and compositions of their own throughout Europe and Russia.
They transcribed Beethoven's "Marcia alla Turca" from The Ruins of Athens for piano; the score was successfully published in 1872.
With the death of her husband in 1882, Marie had the opportunity to study with Liszt in Weimar, and with Camille Saint-Saëns and César Franck in Paris.
[2][8] Saint-Saëns thought highly enough of Marie to introduce her to the Society of Music Composers—a great honor for women in those days.
[7] The New Grove Dictionary of Music states that Marie "composed piano pieces and songs which, though essentially Romantic, reveal an assimilation of the innovations of the time.
"[7] The American Record Guide lists Marie's compositional approach as "romantic in style, with more flavor of the salon than the concert hall.
Jaëll studied a wide variety of subjects pertaining to the functioning of the body, and also ventured into psychology: "She wanted to combine the emotional and spiritual act of creating beautiful music with the physiological aspects of tactile, additive, and visual sensory.
As a result of her studies, Jaëll was able to compile her extensive research into a technique book entitled L'intelligence et le rythme dans les mouvements artistiques.
