Dipping Wings:for flute (alto fl), clarinet (bass cot), tpt, vla, vcl, perc and live electronics

commissioned by Ballet Rambert for 60th Anniversary season, choreographer Mary Evelyn, designer Liz Emmanuel. World premiere: Theatre Royal York 03/06/86

Liminal Lines:work for euphonium and live electronics

This is the first in series of works that explores the edges of musical styles, in particular the musical language associated with the brass band traditions and the relationship between this performance genre and the work of experimental electronic composition.

Superimposition: A composition for harp, saxophone and live electronics

Superimposition is built on a live-scoring system. Computer animated graphics combined with computer generated algorithms produce the score in real time based on preferences input by the composer. Notably, this system introduces a methodology for eliciting complex and coordinated rhythms from instrumentalists through notation generated in real time. This work also incorporates a system for live electronics and live sampling and processing.

Concerto Grosso (working title) - a new work for soloists, brass band and electronics

As with Liminal Lines, this work explores the boundaries between distinct and contrasting musical genres. The use of live electronics within the brass band idiom is novel, particularly in relation to the use of sensors with brass band instruments.

Portfolio of Compositions investigating ensemble improvisation, distributed and real-time scoring, and multi-nodal input and output

This output is a collection of compositions which explore issues of ensemble improvisation, ensemble management and orchestration, real-time and distributed scoring, multi-nodal inputs and outputs, and animated and graphic notation. Compositions include: Activities I; tutti, duet, trio, solo, quartet; Lewitt Notations I; Webwork I; and Sometimes I feel the space between people (voices) in terms of tempos. These compositions are presented in computer animated scores which are synchronized through the network and subject to real-time modification and control. They can be performed by ensembles distributed over large physical spaces connected by the network. The scores for these compositions include software which displays the animations to the performers, software to structure and disseminate score events, and triggering software that allows the control of a performance to be distributed. Scores can also include live electronics which are coordinated with graphic events.

Merula

Merula is a thirty-minute work for bass flute and electronics, commissioned by Icelandic flautist Kolbeinn Bjarnason. The premiere took place in the Belfast Festival at Queen’s in November 2012. A recording will be made in 2014. Further performances in Iceland, Norway and Poland are anticipated in 2014-15. I have given a research seminar on this work at Queen’s and will deliver it again at the University of Oxford during 2013-14.

Research Goals
1) To develop an effective means of notating live electronics in a manner that would sustain the work's performance history beyond the current generation of software
2) To apply the techniques of transcription and spectralism used in my composition, Perseid, using birdsongs as source material
3) To explore the problem of sustaining large-scale form in music that is primarily fast
4) To facilitate the emergence of the solo bass flute as an important solo instrument through the completion of a new large-scale work

Methodology
• Methodologies employed in this project included sound recording, sound analysis and transcription, extensive precompositional sketching, electroacoustic techniques of sound manipulation, designing complex live processes of sound transformation and spatialisation
• A considerable part of this work was collaboration with the flautist, both in SARC and Iceland. Mr. Bjarnason was involved all stages of the work, frequently recording source materials and helping to ensure the idiomatic nature of the flute writing.
• Developing a means of notating the live electronics. Building on a model suggested by Pierre Boulez in Anthemes 2 (1998), the score of this work includes a technical manual that describes electronic processes in a manner that can be reprogrammed in subsequent generations of software. Combined with a system of notations employed in the full score, the technical manual will enable this composition to be performed by a wide range of performers and technical teams, with appropriately identical results.

Correlated electron transport in molecular electronics

Theoretical and experimental values to date for the resistances of single molecules commonly disagree by orders of magnitude. By reformulating the transport problem using boundary conditions suitable for correlated many-electron systems, we approach electron transport across molecules from a new standpoint. Application of our correlated formalism to benzene-dithiol gives current-voltage characteristics close to experimental observations. The method can solve the open system quantum many-body problem accurately, treats spin exactly, and is valid beyond the linear response regime.
