On Saturday, November 23, 2024, at 17:00 CET, the music composition Platonic ID (2005-06) by Rozalie Hirs, commissioned by ASKO|Schönberg, will be performed during the Contemporary Ensemble Academy at the Royal Conservatory in The Hague. The ensemble, under the direction of Joey Marijs, will perform at the Conservatorium Hall, Amare building, Spui, The Hague.

platonic id for ensemble (2005, 2006 rev) is a music composition by Rozalie Hirs. The piece sets out with Plato’s so-called “world soul”, as described in his Timaeus. More concretely, it can be understood musically as several harmonic series with partial numbers 1, 2, 3, 4, 8, 9 and 27. The harmonic world of platonic id consists of these resounding overtone series, as well as their corresponding undertone series, built on different fundamentals. Further materials come from the harmonic relationships between sounding overtones on string instrument and their respective fingerings, on strings of different lengths. Rozalie Hirs previously explored these relationships in her composition article 4 [map butterfly] (2004) for solo violin.

Platonic id for ensemble (2005, 2006 rev) by Rozalie Hirs is part of her dissertation towards a doctoral degree at Columbia University (D.M.A./Doctor of Musical Arts, Graduate School of Arts and Sciences, Columbia University, 2007).
