Twenty years after Chronographie I, Pentagramme uses the same instrumental pattern : flute, oboe (or violin), clarinet, horn (or viola) and bassoon (or cello). Expressive, rhythmic, full of colours and contrasts, this work perfectly captures the current aesthetic of the composer.

Chronographie IX for bassoon and piano, Deux Esquisses for wind quartet, Thrène for alto flute and piano, Sextuor for wind quintet and piano, Pentagramme for wind quintet and Cosmographic Mystery for horn are recorded on the CD Cosmographies by Quartz Ensemble (QUARTZIADE 014).

World premiere in South Korea on 11th August 2010 at Ilshin Hall (Seoul) by Quartz Ensemble.
