Latent Streams

Programme note

Latent Streams is the most recent work in the Streams series. Across these pieces, a stream is a way of organising continuity without requiring everything within it to behave alike. Temporal Streams holds sharply defined piano materials in extended temporal states, allowing outliers to unsettle where one state ends and another begins. Streams (Sketch) brings separate daily orchestral studies into a shared field; its textures would later be reconsidered in Tulpa. Latent Streams turns the question towards style and pulse: how can differently felt beats inhabit the flow of one musical argument?

The score’s introduction describes a dialogue between a more classical manner and a groove- and jazz-influenced one. The contrast is carried by the players’ sense of the beat as much as by their pitches. Short, sharply articulated figures pass between winds, brass and vibraphone; syncopations and recurring low notes invite a more bodily pulse, while shifting metres and tightly subdivided runs continually displace it. The piece asks the ensemble to make those differences audible without allowing the material to fall into disconnected episodes.

On page 17, the music marked ‘manic, incisive’ briefly compresses into quick triplets and sextuplets shared across the upper voices. Then those voices fall silent. Against their absence, the tuba enters softly with repeated, detached notes: a new sense of beat begins inside the space left by the old one. This change shows how the streams relate. They do not simply alternate as separate styles; one current recedes while another becomes perceptible beneath it, keeping the argument in motion through a change of character.
