The research submission is a portfolio of eight compositions: Pure Cold Water (orchestra, 2016), The Greening Variations (piano trio, 2016), Dunford Chorale (alto saxophone and SATB, 2017), The Wish to Disappear (string quartet, 2017) Music Alone (violin solo, 2017-18), Sinfonia Malacia (orchestra, 2018), Watermark (string quartet, 2018-19), Nordhaus Litany (mixed octet, 2019). The accompanying commentary discusses a number of research threads explored throughout the compositions. This includes an interest in teleological structures informed by the large works of Sibelius. These structural concerns are nuanced by a number of other elements which are concerned with repetition and cycles. One such element is ostinati which, influenced by minimalism, is often the bedrock of my work. Informed by Ligeti I explored ways in which the repetitive ostinati could take a form which helps articulate the teleological elements of my work. My harmonic language also makes use of repetitive cycles. I also discuss the influence of medieval techniques upon my work.
