"Journey pieces" are one way of creating a sense of movement and continuity. Howard Skempton's Caves is a good example of this.

John Paynter's Fog is described as a "sound picture for an average class of any age". The score is a mixture of conventional and new notations and includes elements of material devised by the performers.
