(for sinfonietta, 2004)
Cirrus, Cirrocumulus and Cirrostratus are all names of cloud formations to be found in the upper region of the Troposphere. In this musical context they form a trilogy of pieces based on the same underlying compositorical idea. Cirrus or Cirro- is latin meaning a lock of hair. That is: individual hair put together in a collective bundle. Thus, all the pieces including Cirrostratus attempt to create a balance between individual and collective behaviour, where each individual voice brings forth the same musical material but always in slightly different ways.
Cirrostratus was commissioned by Radio France and BIT20.
