Pulsus Flatus Vox (2014) for Flute-Alto Flute, Clarinet-Bass Clarinet, Horn, Trumpet, Trombone.

Performed by Ensemble Intercontemporain during Manifeste festival at Le Centquatre, 2014.

The title Pulsus Flatus Vox (Latin – Rhythm Blow Voice) is derived from the use of musical material.
The form of the piece is binary and exploring opposed possibilities in reading my pre-composition key of the piece. It is founded on very slow pulsations according to prime numbers fulfilled by micro-tonal chromatic in different speed founded on irrational rhythms. The first part has a passive non directional character and the second plays with listeners’ perception: while ears catch the rapid glissando of the horn, the silent and slow ascension through a micro-tonal scale in the low register multiplies itself and begins to dominate transforming a pure sound to a distortion.
