Folia(1980) is intended to be a virtuosic show piece for woodwind quintet. The plan was to compose a work for winds which maintained a high level of intensity throughout. Even the few sustained passages keep the tension high by means of extra technical challenges such as trills of variable speed, flutter tonguing and simultaneous singing and playing. The melodic and harmonic material is entirely based on a major/minor 9th chord in all its inversions which, coloured with unusual overtones, slips in and out of focus much like the variety of autumn foilage. Hints of relaxation and timbral changes are achieved by varying the density of the texture, suggestive of the randomness of nature.
