The record Interplay: Duet for One and for the Other brings together two albums for piano and Disklavier-Diagram and Projection and Spring Scenes-which engaged me as pianist, composer, and producer throughout 2024 and 2025, and which were conceived as an artistic inquiry into the shifting boundaries between human agency and machine autonomy in the contemporary world. This project was carried out as part of the SecondLevel Master's in Piano "Play & Rec", directed by Maestro Roberto Prosseda, with the support of Bösendorfer Klavierfabrik GmbH.The two suites form a unique project worldwide that places Disklavier technology at the very center of both composition and performance-not as separate stages, but as synchronous and interdependent acts within a single creative process. Indeed, until now the Disklavier has been employed as a medium-for performance, recording, or composition-but never as the core of an aesthetic in which all these phases are integrated and mutually influence one another by virtue of it.I chose to regard the aesthetic framework as the common thread linking both suites, while at the same time expressing it in different ways in each project.
