A recurring motive is the distinctive grunt and repetitive "huffs" of the Queensland possum.

In these examples spectrograms of possum sounds are aligned with the notation to demonstrate the approach. Despite the "noisiness" of the possum sounds - significant pitch components are also evident and these are transcribed into pitched material particularly for the piano/melodica and bass clarinet. The contours of prominent pitched components were initially sketched directly onto the spectrogram and then "lifted-off' and adapted into a more traditional notational framework.

The characteristic screech emitted by the possum is transcribed for melodica and bass clarinet multi phonic. Other lower pitched noises are orchestrated by percussion and mid-range glisses by piano.

A variety of grunts and short squeals are also transcribed.

​The "verticalised" contour of the feature was used to determine the volume and left/right spatial orientation (image to the right) of each of three field recordings created by Jocelyn Wolfe. The recordings form the sonic connection to the terrain, forest and river topographies represented in each of the performer's scores.

​The performance was part of my sub-residency within a residency by Clocked Out (Erik Griswold and Vanessa Tomlinson) at the Griffith Conservatorium in Brisbane. The work continues a line of exploration of site-specific work responding to environments, field recordings and landscapes.
The score was created in Perth and relied upon satellite and terrain mapping of the Willsons Downfall locality around Harrigan's Lane. In particular it was assembled from topographical information related to three principal features: the Boonoo Boonoo River, Mount Lindesay Road and the tree line of the Bookookoora mountain ridge (Image to the left). Each feature is represented in the work by one of the performers. 

​Stylised representations of the surrounding landforms were then attached to each of the three lines according to their horizontal and vertical distance on the map (see below). The lines (but not the stylised representations) were then stretched out horizontally to represent the work's 8 minute duration spatially.
