Glitches / Trajectories, as the title suggests, explores audio faults and space, articulated through an 8-channel image. Denis Smalley’s spectromorphological terminology is found to be suitable in discussing the piece; focus throughout is on behaviour and motion and growth processes. Earlier sections contain a degree or imitative and reactionary behaviour (active / instability, emergence / disappearance and empty / fill). Later, trajectorial sound materials explore reaction, interaction, and growth processes such as agglomeration / dissipation.

As the piece developed I found the lines between texture and gesture were becoming increasingly blurred. I have attempted to emphasise this notion through the structuring of the final extended section which applies behavioural variations to gestural sound materials (with a focus on perspectival space, changes in spectral resolution and spatial trajectories), and may be perceived as equal parts texture and gesture.
