Eleri’s compositional interests stem from her interest in mathematics, tuning systems and the harp. Much of her compositional output uses number series, mathematical constructs, or new ways of constructing tuning systems using circle equations. Her compositional influences come from experimental composers such as James Tenney and Alvin Lucier who see composition as an investigation of sound an approach to music that fits in with Eleri’s mathematical ideas for structuring of pieces and other pre-compositional planning. Eleri also has an interest in new music for harp, particularly those making use of retuning and extended techniques.
Eleri was part of the founding committee of the Forum of Composers and Musicians, a student society set up to promote the performance of student pieces and has received performances in their concerts. Her music has also been performed at the Howl for Now celebrations, by the Leeds University Union Music Society (LUUMS) chamber choir and by Leeds Cathedral choir. She has presented papers at the University of Leeds, in Berlin at the Mathematics and Computation in Music conference, at the 2009 UK Microfest and at the 2010 Chaotic Modelling and Simulation International Conference in Crete. Recently her music has been performed at UK Microfest 4 in the Vortex Jazz Club (March 2011), at Tate Britain (April 2011) by Microblech and by the Trio Labyrinth in the University of Leeds (April 2009). She has recently had a piece selected as part of the Cage99 Project by Ensemble Décadanse. Eleri has been appointed as Leverhulme Artist in Residence at the school of Mathematics in the University of Leeds, where she will be composing several pieces and working with mathematicians to combine her two interests and create a creative resource for mathematics students at Leeds.
