Sound of the Machine


The Sound of the Machine by Robert van Heumen

A composition for Disklavier, laptop-instrument and flute with electronics, performed by Shackle (Anne LaBerge on flute with electronics & Deckard on laptop-instrument)

Alternative version for Disklavier, laptop-instrument and voice, performed by Deckard (laptop-instrument) and Stephanie Pan (voice)


The sound of machines is fascinating. They scream, growl, grind, buzz, hum, sing, roar, whistle, thunder. The Disklavier is a machine to make music with. But it's not only the strings that make sound. This composition exposes the Disklavier's mechanism and produces freshly squeezed music.

This composition is written for Shackle, the duo of Anne LaBerge on flute and electronics and Deckard on laptop-instrument. Described is also an alternative version for laptop- instrument and voice, as performed by Stephanie Pan on voice and Deckard on laptop-instrument. In fact, the composition can be performed in various versions: tape only, Disklavier & tape, Disklavier, tape & one performer, Disklavier, tape & two performers. The length of the piece is 15 minutes and 21 seconds.

The composition consists of three sections:
  1. Huilen ruisen: tape and Disklavier only, exposing the mechanism
  2. Grommend schreeuwen: feature section for the live players
  3. Zoet zingen: a movement of noise into melody, ending with the sound of the piano
All sounds heard on the tape are derived from the Disklavier. Flute, voice and live sampling of those instruments by the laptop-instrumentalist are used to bridge the gap between tonal material from the piano and mechanical sounds from the mechanism of the Disklavier.

The Sound of the Machine is commissioned by the Conlon Foundation and the Gaudeamus Muziekweek and made possible through a grant by the Performing Arts Fund NL and support from STEIM.

The compositon is performed on the following dates: It will also be added to the repertoire of Shackle, possibly to be performed during their Australia tour in 2012.
