Katharina Maria Leopoldina Cibbini-Koželuch was born on February 20, 1785, in Vienna, then one of the greatest centers of European musical life. She was the eldest daughter of composer, pianist, and music publisher Leopold Koželuch, an important figure in the Viennese classical music scene, who became her first teacher and role model. From an early age, she received a rigorous musical education, developing a virtuosity on the piano that quickly earned her recognition in the city's salons and concerts.

She soon studied with Muzio Clementi, one of the most famous pianists and teachers of the time, which further enriched her technique and stylistic language. Her circle of friends and colleagues included such notable musicians as Beethoven and Moscheles, who appreciated her musical sensitivity and instrumental mastery.

In 1809, she married Anton Cibbini and adopted the name Cibbini-Koželuch. This marriage, while elevating her social status, also marked a turning point in her artistic career. She gradually ceased her public appearances to take up duties at court: she was appointed lady-in-waiting to Empress Caroline Auguste of Bavaria, a prestigious role that brought her into the world of Viennese high society.

An active composer, Katharina Cibbini-Koželuch published several works for piano that reflected the tastes of her time: Introduction and Brilliant Variations, Brilliant Divertissements, Six Waltzes for Piano, and a Grand Trio Concertante for Two Pianos and Cello. These pieces combined virtuosity, elegance, and melodic sensibility, and were well received in Viennese musical circles.

Katharina Cibbini-Koželuch died on August 12, 1858, in Zákupy, Bohemia (now in the Czech Republic), where she had spent her final years.
