In this work scored for strings, Sculthorpe has explored a variety of textures create variety and contrast to highlight the programmatic character of the music. The various layering and instrumental roles reflect current compositional practices.
In the prologue "The Bush", Sculthorpe explores a homophonic texture where markings such as f, accent (>) and pizz reinforce the expressive directions " con ferocita". The four bar melodic line of the aboriginal chant theme in violin I which is underpinned by accents in violin I & II, viola (arco) against " f pizz", double stopping of cello and double bass "f pizz" creating a close texture. The use of creates a contrasting textural effect. This figure is followed by almost two bars rest creating contrasting texture. The opening focuses on register three layers consist of violin I melody, violin II, viola close harmony (tone clusters) cello and double bass with each main section the texture changes 1 the cello moves to a broken chord figure over 5th creating an ostinato in contrast to the other Prologue three layers which continue; creating a thicker homophonic texture or multi-layering effect with minimal of bars creating a close texture.
In the coda 3 the texture thins dramatically with the melody fragmented in violin I, drone in cello and pedal point in double bass while violin II introduces new performance directions . Harmonic played between bridge and tail place on string indicated which appears in violin II playing a rapid syncopated idea creating a glassy and screechy effect tone colour, creating contrasting texture. .
The viola also enters with contrasting and highly coloured marking "sul pont" (play on the bridge) creating a glassy effect and texture. The four parts appear in multi-layered staggered entries. .
