Her work explores connections between acoustic and synthetic sound. This process is often grounded in rational tuning systems, through which she constructs rich drone structures that reveal the expressive potential of microtonal, electroacoustic tensions. Interactive sonification systems also form a significant part of her artistic practice. Between 2017 and 2022, Słyż carried out artistic research involving practical experiments with movement sonification and different forms of interaction.
Her compositions have been presented at many contemporary and experimental music festivals and major venues including Rewire Festival, CTM, Aarhus Festival, Unsound, Warsaw Autumn, Fiber Festival, Kyiv Music Fest, ORF musikprotokoll, The Royal Concertgebouw Amsterdam, Fylkingen, Alice Tully Hall, Ancienne Belgique, Stadtcasino Basel, Kunsthalle Helsinki, NOSPR, Aarhus Domkirke, MeetFactory, Dom im Berg and silent green. They have been performed by leading contemporary orchestras and ensembles such as the National Polish Radio Symphony Orchestra, the Basel Sinfonietta, the Sinfonietta Cracovia, the 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 “under 30” categories at the 71st International Rostrum of Composers (IRC). In the same year, she was invited by the Museum of Modern Art in Warsaw and London’s The Wapping Project as the first artist to create new compositions for the legendary instruments of the Polish Radio Experimental Studio, which had not been used for more than two decades. The works The Long Pause Gives Way and The Long Pause Gives Way II were presented during the Sonics & Scenics festival in Warsaw, 2025.
