Aleksandra Słyż is a Polish composer, musician, and sound engineer. She holds degrees from Adam Mickiewicz University in Poznań, the Poznań Academy of Music, and the 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 and electroacoustic tensions.
Interactive sonification systems are another major part of her artistic practice. Between 2017 and 2022, Słyż conducted artistic research involving, among other things, practical experiments on movement sonification and various types of interaction.
Her works have been presented at prestigious contemporary and experimental music festivals and in major venues including Rewire Festival, CTM, Aarhus Festival, Unsound, Fiber Festival, NODE, Warsaw Autumn, Kyiv Music Fest, ORF musikprotokoll, Open Source Art Festival, The Royal Concertgebouw, Fylkingen, Ancienne Belgique, Stadtcasino Basel, Kunsthalle Helsinki, Aarhus Domkirke, MeetFactory, Dom im Berg, silent green, and Kunsthal Gent.
Aleksandra’s compositions have been performed by exceptional 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.
