Sidechaining by DAVID BRUCE


"Sidechaining...had the assurance of a new-minted classic" The Independent
"a piece that combined neoclassical wit with the huge energy of a tarantella." The Telegraph

Just as photography had a profound impact upon painting, I’m fascinated by the way recording and,later, digital technology have affected acoustic music-making. As well as the more subtle or indirectinfluences, I’ve sometimes wondered, could some of the techniques and effects used in digitally createdmusic work in, say, an orchestral environment? Well, in this piece I decided it was time to find out.

Sidechaining is a process used in digital-audio software by which the music in one channel affects themusic in another. Imagine a long chord. Now imagine the beat of a drum. Each time the drum beats, theheld chord just briefly cuts out or reduces in volume. That’s the essence of sidechaining. Another use ofthe process is when DJs automatically reduce the volume-level of music while they are speaking over it.Sidechaining can be used as an interruption, but it can also be a kind of trigger, one sound causingothers to launch; or it can be used repeatedly to create a sense of interaction between two separateideas.

The notion of one instrument interrupting or stealing the melody from another relates, for example, to themedieval technique called ‘hocketing’, in which a single melodic line is passed between of two or moreinterlocking voices or instruments (this happens at one point in my piece between oboe and clarinet,although in a distinctly un-medieval-sounding way); it also relates to the way rhythms are built up by apercussionist in, say, Latin music – a steady stream of notes is split between two percussion instruments:when one is playing the other is not, and vice versa (this also happens in my piece). You could think ofeach of the two interlocking parts as being the ‘negative’ (or ‘inverse’), rhythm of the other.

To me, there’s something very satisfying about making some of these effects on a grand scale in theorchestral arena. The opening bars for example, switch back and forth between two parts of theorchestra, almost as if some hidden hand is turning the volume knob up and down. The opening soundsare ones of power and energy, but elsewhere the effect can also be comical – the French horn inparticular, being the loudest of the soloists, has a tendency to playfully cut the other players off mid-stream.

The commission was for a piece scored for four soloists and orchestra, lasting 10 minutes. While thisinevitably leaves little time to fully indulge our four supremely talented soloists, I hope this joyful and good-humoured piece will encourage a general celebratory sense of goodwill in the musical communityand a sense of how lucky we are to be surrounded by such talent.


The following two videos also relate to Sidechaining, the first is a vlog I made shortly after the premiere, the 2nd describes some of the ideas involved in the piece:

David Bruce's Sidechaining made for an exhilarating listen.

David Bruce's Sidechaining may have been conceived as a technical exercise in layering and hocketing, but it had the assurance of a new-minted classic. / Jul 2018

" ..[a] robust and mature demonstration of orchestral playfulness. The work is essentially a quadruple concerto, the solo roles featuring Young Musician alumni Michael Collins (clarinet), Nicholas Daniel (oboe), Jennifer Pike (violin) and Ben Goldscheider (horn). Beginning with a nicely weird melodic idea, where each note swells, punctuated by brass and timpani flourishes, Bruce guides the music through a series of episodes that provide opportunities for each soloist to do their stuff. Initially it’s all a bit of romp - clarinet and oboe firing off notes at breakneck velocity - though this is countered with shifts into more leisurely and toned-down territory. Particularly noteworthy is the highly lyrical sequence that emerges a few minutes in, appearing from nowhere but managing not to derail the work's onward sense of momentum, one of a number of such instances where the music successfully negotiates quite extreme gear changes.

It's great when obviously playful music doesn't feel the need to sacrifice compositional rigour in order to make concessions to expectation, and Sidechaining's conclusion is a good example of this, Bruce appearing to set up an obvious galloping climax, only to redirect it with a return of that strange opening melody, and then interrupt it entirely with another unexpected burst of slow lyricism, leading to a relatively delicate chirping conclusion featuring only the soloists. Very nice.
