Water Pail Instrument

This page documents instrument-building works that transform everyday objects, found materials and constructed mechanisms into performable sound systems. The instruments are not treated only as tools for producing sound, but as sculptural, spatial and performative objects.

The Water Pail instrument brings together metal pails, bamboo, water, percussion materials, amplified vibration and field recordings. It sits between percussion, object-based sound art and installation practice, where the physical behaviour of the object becomes part of the musical material.

The section below expands this practice through the related cooking oil drum instruments, where transducers activate large metal drums as resonant sound objects.

The following section focuses on the cooking oil drums as sound objects, including their use as transduced resonant bodies within the larger installation environment.

Cooking Oil Drums as Sound Objects

This instrument-building work uses cooking oil drums, transducers, bamboo, water pails, low-frequency sine tones and field recordings as a sculptural sound system. Developed within the installation and performance context of Water Pail, the work treats everyday containers as resonant bodies, transforming industrial and domestic materials into amplified instruments. The bamboo and water-pail structure forms part of the same built instrument environment, extending the work beyond percussion into object-based sound installation.

Instrument System

The installation uses cooking oil drums as resonant sound objects. Transducers attached to the drums activate the metal surfaces with low-frequency sine tones and field recordings, turning each drum into an amplified body rather than a conventional loudspeaker.

The performed component is for solo percussionist using brushes, soft and rubber mallets, finger cymbals, metal güiro, water and an exposed speaker. These actions are played on two metal water pails with a moving bamboo and water-pail structure, creating a physical dialogue between hand-played percussion and transduced resonant objects.

Installation and Scale

The instrument can be realised as a performance system or as part of a sound art installation. In this version, the oil drums, pails and bamboo structure formed a spatial arrangement of sounding objects that could be expanded according to the size of the site.

While 8 drums were used for this installation, future iterations could include any number of pails, such as 10, 16, 21 or 40, or any number of percussionists, so that the instruments fill the entire space.

PVC Recorder Experiments: Studies for Dream Recorder

These PVC experiments formed a practical sketchbook for Dream Recorder: Waking, a contrabass recorder work that extends the instrument through preparations, resonating objects and real-time electronics. The studies test how breath, tube length, membrane vibration, transducer excitation and nearby sound objects can become part of an expanded recorder system.

Prepared breath, resonant objects and electronic activation

The prototype tests how a recorder-like tube can be expanded through preparations and simple electronic systems. The work combines acoustic techniques such as tube-length changes and mouthpiece membranes with external resonators including a spring drum, waterphone, toy piano insides, tin foil and chopsticks.

Variable tube length Changing the length of the tube alters pitch and shifts the behaviour of the air column.
Balloon membrane A rubber membrane over the top adds a fragile, pressure-sensitive surface.
Transducer excitation A speaker/transducer activates the instrument physically through rattling vibration.
Bluetooth control Buttons trigger added electronics while the instrument remains playable by breath.

Connection to the finished work

From PVC prototype to Dream Recorder: Waking

These PVC studies led into the contrabass recorder work Dream Recorder: Waking. The prototype stage developed a vocabulary of extended recorder preparations: resonating objects placed near the instrument, physical vibration through a transducer or speaker, and electronic control systems that could be played while performing.

Real-time electronic control

In Dream Recorder, the electronics are controlled in real time using two Bluetooth Mini Programmable Macro 4-Key Keyboards. Both keyboards are attached to the body of the recorder using Blu Tack and controlled wirelessly through Ableton. The dial also functions as a button and is mapped as another note in the 36-EDO scale. To allow the computer to register the two units as separate devices, one keyboard is connected via USB-C.

A low-frequency sine tone plays through the speaker and can be controlled by the Bluetooth keys.
The speaker can also rattle the instrument.
If the sine tone is the fundamental frequency, or part of the harmonic series, it resonates with the instrument and complements tones blown through it.
This is a transducer. It is also a speaker, but it rattles back and forth much more.
It can also be controlled with the buttons.
A spring drum sits next to the instrument and can be activated while playing.
