Musicology, having been transmitted as a compilation of disparate events and disciplines, has long necessitated a 'magic bullet', a 'unified field theory' so to speak, that can interpret the steady metamorphosis of Western art music from late medieval modality to twentieth-century atonality within a single theoretical construct. Burnett and Nitzberg challenge the traditional understanding of development, and advance a new theory of eleven-pitch tonality as it relates to the corpus of Western composition. The book plots the evolution of tonality and its bearing on style and the compositional process itself. The authors move beyond existing theory and analysis to base their theory from the standpoint of chromatic 'pitch fields'. These fields are the specific chromatic pitch choices that a composer uses to inform and design a complete composition, utilizing specific chromatic inflections to control a large-scale working out process that is the very essence of 'development'. In short, the authors claim that a chromatic background that coexists with a diatonic contrapuntal background may define the process of compositional development. These chromatic and diatonic events are the two genus expressions of slowly unfolding tonic octaves.
