Molecules (2000) for piano by Aldona Nawrocka presents a unique synthesis of the most prominent paradigms of the musical avant-garde. This multidimensional composition of variable structure, dedicated to the eminent pianist, composer, and improviser Szabolcs Esztenyi (1939–2024), is distinguished by an intertextual frame consisting of classical Latin maxims transliterated into Morse code.

In Mirror Music for piano and electronics (2008) by Stanisław Bromboszcz, the central focus remains on the piano sound, enriched by an electroacoustic layer, which becomes a multi-faceted medium exploring the concept of mirroring.
