Polish composer, she holds degrees from the Adam Mickiewicz  University in Poznań, Poznań Academy of Music, and Royal College of Music in Stockholm.

In her compositions, she explores connections between acoustic  and synthetic sounds. This process is often rooted in rational tuning systems, through which she constructs rich, complex drone  structures that highlight the power of microtonal, electroacoustic  tensions. Interactive sonification systems are another major part  of her artistic practice. Between 2017 and 2022, Słyż conducted  artistic research involving practical experiments on movement  sonification and types of interaction.

Her works have been presented at prestigious contemporary  and experimental music festivals and in major venues including  Rewire, CTM, Aarhus Festival, Unsound, Warsaw Autumn, ORF  musikprotokoll, Royal Concertgebouw Amsterdam, Fylkingen,  Alice Tully Hall, Ancienne Belgique, and Stadtcasino Basel.

Her compositions have been performed by leading contemporary  orchestras and ensembles such as the Polish National Radio Symphony Orchestra, Basel Sinfonietta, Sinfonietta Cracovia, Orchestra of Futurist Noise Intoners, and the Spółdzielnia Muzyczna  contemporary ensemble.

In 2025, her composition Suspended in Ratios was recommended  in both the general and the U-30 categories at the 71st International Rostrum of Composers. That year, she was also invited by  the Museum of Modern Art in Warsaw and London’s The Wapping Project as the first artist to create new works for the legendary instruments of the Polish Radio Experimental Studio, unused  for over two decades and never before performed live. The works  The Long Pause Gives Way and The Long Pause Gives Way II were  presented at the Sonics & Scenics festival in Warsaw in 2025.
