rozalie hirs: spectralisms in my music

Venus [morning star] (2010)

Spectral analysis, Risset/Shepard tone

In LA (2003; 2010 English version)

In LA (2003, Dutch version) was composed as a portrait of the composer Louis Andriessen and is dedicated to him. The text is based on an interview with Andriessen that Hirs conducted in 2003 inquiring after his first memories. In 2010 Hirs translated the piece into English.

In LA (2003, 2010) is inspired by the psychoacoustic ‘cocktail party effect’, which was taken as a metaphor for the act of remembering, for ‘hearing’ a particular stream of memories within a cacophony of competing memories during its emergence into consciousness.

article 7 [ways to climb a mountain] (2012) by Rozalie Hirs is a microtonal composition for bass clarinet and electronic glissandi, synthesized from pure sine waves, employing binaural beatings and ring modulation only. The instrumental lines are enveloped by, or cut through, the glissandi moving in several large waves.
