In the context of this commentary the term, 'Using New Technology', means that new technology has been used both in the creation of the compositions and as part of the compositions themselves. The notion of duality is a structural motive found throughout the works in this folio.
The specific areas to be discussed in this commentary are:
• the genesis of the compositions
• compositional principles used
• issues of interpretation of notations and instructions and realisations of the works in performance
• guidelines for analysis of the works and their reception
• the contribution of these works to the development of music
The three works Guitar Concerto, time lines and Chiaro Scuro were all composed and scored using digital technology. Each work contains a significant electroacoustic component which makes use of digital technology as an integral part in the performance of the works. Realising performances of the works without such technology is possible but is not given consideration in this commentary. The reason for this is that judgements in relation to aspects of resonance, balance and orchestration have been made assuming that the types of technology described are used in performance.
From conception to finished work, computing technology has played an integral part in the writing and the development of these works. Demonstration recordings and finished scores are also outcomes which have relied on this technology. The central components of this technology are M.I.D.I (Musical Instrument Digital Interface) and hard disk recording. The process of computer assisted composition lies at the core of my compositional method.
