George Benjamin's Flight for Solo Flute.
Published by Faber Music.

'This 8-minute solo flute piece, written in 1979, was inspired by the sight of birds soaring and dipping over the peaks of the Swiss Alps. Equally important to me at the time, however, was the challenge to produce clear, dramatic structure and harmony within a monody restricted to the flute’s three-octave compass.'
