Maria Agata was born December 14, 1789 from a Samonon ben Elisz family called Szloma z Rohatych. The entire family converted to Catholicism in 1759. Her father, Francizek Wołowski, had a brewery in Warsaw. Her mother, Barbara Lanckorońska, was well educated. They taught her to dance, to play piano, and to speak foreign languages. After two years of lessons, her teacher, Antonin LIsowski, advised them to find her better teacher than he. So she studied for four years under Tomasz Gremm. She not only played music, she composer music, and gave organized concerts. She was also a good painter.

Rode, pianist Daniel Steielt and opera composer Ferdynand Paér were among their guests. Her parents, seeing her talent, sent her to Paris in 1810. The director of the Paris conservatory dedicated her Fantazja for piano. After her return, on March 21, 1810, she married Jósef Szymanowsky and tried to be a good wife for 10 years, spending summers in Otwock and winters in Warsaw. At her parents' salon, she met Gasapro Spontini, Jan Ladslav Disika (a Czech pianist and composer), August Klengel, the Italian singer Angelica Katalan, and a son of Wolfgang Amadeus Mozart. After five years of marriage, she decided on an art career, beginning with a concert at the Vienna Congress. Tzar Alexander was enchanted and invited her to St. Petersburg. Although she was a great success, her husband and parents were not happy, especially her husband who wanted to see her in the house. So they separated. She wanted to educate her three children alone. For two years, she practiced the piano and on April 2, 1822 began playing in Moscow and June 17 in St. Petersburg. The concerts were attended by Tzar Alexander and his wife. At the end of 1822, she received the title "First Lady Piano Player of Her Highness Tzarina Elizabeth Alexandrowna and Maria Fiodorvna".

One of her concerts was for Fredrick William III and his court. She had concerts in London before George IV, too. She composed minuets, polonaise, mazurkas, nocturne, fantazje, etudes. In 1816 Karol Kurpińskishe dedicated one of his work to her, as did Jan Nepomucen Hummel in 1822. She was in contact with John Field, Felix Mendelssohn, Bartholdy, Fredrick Chopin, and Michal Glinka.
