The quest for homogeneity/differentiation and the process of timbral/sonic derivation – which accompany the flute's passage through different, alternating acoustic spaces – can be heard, for instance, in the use of noisy/breathy and "percussive" components of the flute's sound, which are quoted and amplified by similar material in the ensemble. Moments of proliferation and multiplication of sound material are followed by sections in which the compositional elements generated are distributed to the entire ensemble – through an instrumental writing built out of echoes and fragments, references and "shifting pedal tones" – spreading out and moving through space by means of resonances and subtle trajectories of acoustic propagation.
