Several compositional ideas are explored in this work and are sustained throughout. The first is the extensive use of quintuplets, which give the instrumental parts fluid rhythmical character. The second idea is the derivation of a six-note scale that generates much of the instrumental writing. In the opening section the violin uses a scale of six notes (C, D#, E, F#, G & A#), while the clarinet explores other unused pitches (F, G#, A, B, C#). Despite extensive chromatic writing, it is the six-note scale that forms the generative seed of the entire work, and these pitches are given a high degree of prominence. The clarinet and violin are set against the harmonic language of the piano accompaniment. My intention was to create a static cycle of chords, which would act as a backdrop for the instrumental dialogue, eventually repeating itself. A rhizome is a horizontal, root-like stem that extends underground and sends out shoots to the surface. Deleuze and Guattari used the term to describe types of non-hierarchical networks. “The rhizome is reducible to neither one nor the multiple… It is composed not of units but of dimensions, or rather directions in motion.” (A Thousand Plateaus, 1987, p.21). The character of the work is defined by elements that are non-hierarchical in nature and hence to a certain degree rhizomatic. Musical composition may be perceived as an “assemblage”, as the outcome of several different elements, which provide levels of expression and content for one another through their inter-connectivity. This composition was primarily influence by my interest in Messiaen and the manner in which he combined clarinet, violin and piano in the Quartet for the End of Time. Another influence on this work was Bartok’s use of Bitonality in his piano music and the idea of the simultaneous use of mutually exclusive pitch sets.

Performance Notes: The piece is notated without a key signature. All accidentals follow the normal conventions, in which the accidental marking holds true for the entire bar it appears in. The piece requires a B-Flat clarinet, but this score is notated in the actual pitch, rather than the transposed version.

Which method of viewing music should I use?

Score Exchange has two methods to display previews of music: seView which uses regular html and javascipt and the Scorch plug-in from Avid which needs to be downloaded and installed onto your computer. Both have advantages and disadvantages:


seView, is the most compatible option. You should be able to view music on all modern web browsers including most mobile devices. Even if your device does not support javascript you should still be able to preview at least page one of the music.

You do not need to install any additional software to use seView.


Scorch is a free plug-in from Avid for displaying and printing music. It can also play the music that you're seeing. As modern web browsers are updated, Scorch is no longer compatible with many browsers. Scorch has never been compatible with mobile devices and some web browsers on Mac computers.

If your web browser does not install Scorch automatically, you can click here to download and install scorch manually.

Static preview

The static preview shows a basic image of the first page.

Interactive preview

The interactive preview also shows a preview of the first page, but it's a bit slower to load. The preview is displayed using the Sibelius Cloud Publishing technology from Avid. With most scores, this technology will provide a higher quality preview, as well as being able to switch to full screen mode and also play the displayed music to you.

Printing after purchase

After you have purchased this item the Cloud Publishing technology is utilised to provide the printing mechanism for the music. As such, we recommend checking that the Interactive Preview displays correctly on your device before committing to a purchase.
