Programme Note:
Isomorphia was commissioned by the National Youth Orchestra of Canada in 2013.

The work is part of a triptych of pieces with the same shape (literally the meaning of the title), including an acousmatic piece, an orchestral piece, and a mixed piece interpolating between environmental sounds and their orchestral transcriptions. The piece's genesis is in a collection of field recordings, variously of animal vocalisations, natural soundscapes and urban environments – I was interested in unlocking the tensions and commonalities between these sounds and the kinds of spaces they represent, while embedding them in the cultural memory and context of an orchestra.

How can an orchestra be like an ecosystem? Almost all of the instrumental writing is based on transcriptions of these environmental sounds. They are assembled into different 'ecological niches', different registers and timbres that exist in balance and unbalance. In the mixed version, the sound's source is always in flux: a bird call transforms into an oboe line, a car horn to a dense orchestral chord – the model becomes the copy. Placing these sounds in an aesthetic context is as much about framing their natural beauty as it is about calling into question their fragility and negotiating their post-industrial context; the reproduction of the sound attempts at once to preserve and manufacture.



Most of the field recordings used in this piece were made by the composer, but some are taken with permission from Jean C. Roché and the World Soundscape Project library.
