article 1 to 3 for solo piano (2003) by Rozalie Hirs investigates the resonance properties of the grand piano, its body, and strings. It consists of three movements, [the], [aleph], and [a] respectively. The first movement [the] serves as an opening, emerging from the depths of the piano register. The center movement [aleph] is a meditation on the relative positioning of the piano keys, and on weightlessness. The large, virtuoso leaps render a light, transparent character, that offers space for reflection. The third movement [a] serves as an after-thought, exploring the possibilities of fireworks in the higher piano register. [a] employs an impressionistic piano technique and lyricism, that is reminiscent of Feux d’Artifice (Préludes book II) by Claude Debussy.
