The overriding picture that emerges from the scrutiny of the sketches for Peter Maxwell Davies's Third Symphony (1984) is the remarkable insight it affords in demonstrating a highly proficient composer in total control of his material. He is the consummate workman: diligent, methodical, economical. Indeed, his rather cerebral approach can be construed as objective – purely in the sense of the detached and calculating nature of the sketches, seemingly free as they are from spontaneous outpourings of instinctive musical inspiration. Nevertheless, Davies's method of composing endows the overall project with a sense of cogent direction and powerful meaning. Such discernment is not easily achieved, and has to be carefully planned early on in the work's genesis; certainly, the Third Symphony – a prodigious piece of architecture lasting almost one hour – is enriched by its preliminary working-out. Furthermore, Davies's employment of precompositional determinants, such as Magic Squares and pitch and durational matrices, is so integral to the overall construction of the piece that there exists a susbstantial volume of material, soley devoted to precompositional workings for the work.
