Coro pêndulo
Pendulum Choir é uma peça coral original para 9 vozes A Cappella e 18 macacos hidráulicos. O coro é constituindo por um corpo vivo e sonoro. Esse corpo se expressa por meio de vários estados físicos. Sua plasticidade varia de acordo com sua sonoridade. Varia entre sons abstratos, sons repetitivos e sons líricos ou narrativos. Os corpos dos cantores e suas vozes brincam com e contra a gravidade. Eles se tocam e se evitam, criando polifonias vocais sutis. Ou, apoiados por sons eletrônicos, rompem sua coesão e explodem em um voo lírico ou se dobram em um ritual obsessivo e sombrio. O órgão viaja da vida à morte em uma alegoria robótica onde a complexidade tecnológica e o lirismo dos corpos em movimento se combinam em uma obra com acentos prometéicos.

Pendulum Choir is an original choral piece for 9 A Cappella voices and 18 hydraulic jacks. The choir is constituted by a living and sonorous body. This body expresses itself through various physical states. Its plasticity varies according to its sound. It varies between abstract sounds, repetitive sounds and lyrical or narrative sounds. The singers’ bodies and their voices play with and against gravity. They touch and avoid each other, creating subtle vocal polyphonies. Or, supported by electronic sounds, they break their cohesion and explode in a lyrical flight or bend in an obsessive and dark ritual. The organ travels from life to death in a robotic allegory where technological complexity and the lyricism of moving bodies combine in a work with Promethean accents.

Flutter Hologram: Pendulum
Présentant différentes espèces de papillons dans une seule cloche, le premier, un albatros orange de l’Est, originaire d’Indonésie, est peint dans une teinte orange sanguine accrocheuse. Le yeoman commun contrasté possède des ailes orange fauve, presque dorées, qui battent rapidement lorsqu’il vole dans son environnement. Ils sont accompagnés du troisième papillon, un albatros chocolat d’Asie du Sud-Est. Un anneau en laiton physique est situé à la base de la cloche, tandis qu’un pendule, suspendu au dôme, agit comme un appareil sur lequel se posent les papillons – une allusion à la façon dont la vie est en jeu. Dans un état passif, les papillons habitent calmement la cloche en verre. Cependant, lors de l’interaction, ils voltigent avec excitation, atterrissant parfois gracieusement sur le pendule et l’anneau de laiton, tandis que d’autres, frappant simplement directement les objets.

Gravity harp
Este instrumento fue diseñado por Andy Cavatorta, encargado de hacer robots musicales en el MIT Media Lab. Se ocuparon 4 pendulos de once cuerdas cada uno para hacer esta arpa gravitacional. Hay un software que controla la rotación de cada péndulo y determina la nota que suena dependiendo de su posición dentro del balance del instrumento. El sonido de este instrumento se puede escuchar en la canción de “Solstice”.

Chronos XXI
Chronos the god of time, permanently destroys and recreates. He who symbolises evanescence and return, was the thematic point of departure for the creation of the kinetic media installation Chronos XXI. The piece is a ‘finger exercise on antiquity’ by our Creative Director Joachim Sauter and was created during his residency at Villa Massimo in Rome. A pendulum continuously swings in front of a monitor. This motion controls the slow synthesis and destruction of depictions of Chronos on the monitor. Chronos appears in various interpretations by painters of the late Renaissance, Baroque and Classicism – as a man who disrobes Veritas, as a performer of volatile music, or docking Cupid’s wings, or as children and crop eating, a scythe and an hour glass carrying, beardy and winged old man.

Wave wall
A wall of 122 wind-activated pendulums are each magnetically coupled with its neighbors so that the whole wall moves as a slowly undulating surface similar to a large piece of fabric rippling in the wind. In winds greater than 15 knots, the wall’s coherent wave-like movement becomes more chaotic as the pendulums break their mutual magnetic coupling. The pendulums can also be manually activated.

Initiation
Initiation is an open-end ceremony initiating the audience to the cult of infinity. The gigantic human-machine-interface is driven by the officiants controlling ancestral tools. As time seems to suspend itself, the crowd emerges into an ever hypnotizing state of oscillation. In this place the swing of the pendulum acts as the ever stimulating vector to guide the audience onto higher grounds.

TH-42PH10EK x 5
Five screens were installed by the artist as pendulums that swing continuously. As soon as all five have come to a standstill, they are pulled back into their original positions with the help of cable winches and are made to swing again – triggered by pulling a rip cord, a performative act that cannot take place without human intervention and which involves the exhibition supervisor in the installation. Each cycle, which lasts approximately 45 minutes, ends as soon as all five screens have come to a standstill and no more sound is produced by their movement. The sound is produced by the amplification of the friction to which the joints of the moving pendulum are subjected. Multiplication thus creates five oscillating loops that merge into one another with a time offset.

One Two Three Swing!
One Two Three Swing! challenges society’s apathy towards the political, environmental and economic crises of our age. The installation is experienced in three states: apathy, production and movement. The state of apathy compromises a large pendulum suspended by a 20 metre cable from ceiling and swinging above a 770 square metre carpet in a colour scheme inspired by British currency. Occupying the far end of the hall is the state of production, a factory station where swing seats are assembled, stamped and stored prior to distribution and use. Emerging from the state of production, an orange line formed of sets of interconnected, three-seated swings invite and frame the movements of users.

Sound City
Suspended from the ceiling by two springs and equipped with an oscillating weight fixed inside its body, a Sound City loudspeaker shakes in a disorderly manner in space. The music it plays reacts directly to the movements as if the musicians were inside the loudspeaker and trying in vain to adapt their playing to the turbulences. The originality of the movements comes from the pulsations and interferences produced by the interaction of two coupled harmonic oscillators (the spring and the pendulum) not having the same natural frequency. The two pneumatic jacks to which the springs are attached control the amplitude of the swings.

Pendulum Music

Reich came up with the concept while working at the University of Colorado. He was swinging a live microphone in the style of the cowboy’s lasso, and noting the produced feedback, he composed for an “orchestra” of microphones.Three or more microphones are suspended above the speakers by means of a cable and stand. The microphones are pulled back, switched on, and released over the speaker, and gravity causes them to swing back and forth as pendulums. As the microphone nears the speaker, a feedback tone is created. Different lengths of cable will swing at different speeds, creating an overlapping series of feedback squeals. The music created is thus the result of the process of the swinging microphones.

our time

Our Time (2016) is the latest large-scale installation by United Visual Artists investigating our subjective experience of the passing of time. How long is a moment? At what rate does time actually pass? The work joins a series of kinetic sculptures that began with Momentum (2013); an installation designed as a ‘spatial instrument’ that was to reveal the relationship between expectation and perception when intersected with a physical space.
Our Time defines a physical environment where pendulums swing at a pace apparently unhindered by the laws of nature and where no single time measurement applies. The installation combines movement, light and sound as a multi-sensory, multi-dimensional canvas the visitor can enter. Pendulums swing, each to their own rhythm, as time flows through the grid. With light tracing the path and sound its echo, the passing of time becomes almost palpable.

Pendulum Choir

Pendulum Choir is an original choral piece for 9 A Cappella voices and 18 hydraulic jacks. The choir stands on tilting platforms, constituting a living, sonorous body. That body expresses itself through various physical states. Its plasticity varies at the mercy of its sonority. It varies between abstract sounds, repetitive sounds, and lyrical or narrative sounds. The bodies of the singers and their voices play with and against gravity. They brush and avoid each other creating subtle vocal polyphonies. Or, supported by electronic sounds, they break their cohesion and burst into lyrical flight or fold up into an obsessional and dark ritual. The organ travels from life to death in a robotic allegory where the technological complexity and the lyricism of the moving bodies combine into a work with Promethean accents.

Eggsistential Angst
“I thought it would be fun to pit a large metal machine against a small fragile object,” says Mendoza. “When people look at the egg darting around on a long stick to avoid the pendulum they seem to see it like a Looney Tunes cartoon with the big lumbering pendulum forever chasing the egg but never quite catching it.”

Swinging Pendulum

Suspended from automated grids, more than 400 pendulums are activated to initiate a sweeping 15 part counterpoint of tempi, spacial juxtaposition and gradients of centrifugal force which offers the spectator a constantly morphing labyrinth of significant complexity. The spectators
are free to attempt a navigation this statistically unpredictable environment, but are requested to avoid coming in contact with any of the swinging pendulums. This task, which automatically initiates and alerts the spectators innate predictive faculties, produces a lively choreography of manifold and intricate avoidance strategies.

Pendulum Sound Machine

Symphony in D Minor

‘Symphony in D Minor’ is an interactive sound and video installation on an epic scale. A thunderstorm contained within a series of large hand cast resin sculptures, each individual form is a unique instrument hanging from the ceiling. Suspended just within reach and activated by touch, the viewer sets the symphony in motion by pushing the forms through the air to trigger the various sound elements of the storm. Sensors relay individual recordings of thunder, lightning, wind and rain with alternating intensities to a full-scale sound system. Acting as both conductor and musician, the viewer creates an evolving composition out of atmospheric sounds, forging an environment that envelops the audience. Housed within each piece are 2 video projectors employing mapping software to evenly fill the surface of the forms. Like giant illuminated pendulums each sculpture radiates video projections that in their dormant state display abstractions of water droplets and slow moving clouds. As the sensors detect movement different ranges initiate more visual elements of the storm. Once activated, the form then shifts to a swirling torrent of clouds.

Simple Harmonic Motion study #5d

Behind the different incarnations, at the heart of the project lies the concept of creating complexity from simplicity. Through the use of custom software, a number of ‘agents’ are created and assigned a simple behavior. Each follow an extremely simple repetitive pattern of movement and sound. On their own, each agent is relatively monotonous, basic and mechanical. The repetition duration, motion and sound of each agent is precisely tuned such that the collection of all agents moving together, creates a unique, evolving and complex composition – both visually and sonically. The seed of inspiration comes from the motion of pendulums and other fundamental oscillatory phenomena which exhibit simple harmonic motion. The project extracts and amplifies these complex patterns, both through visual abstraction and emphasis; and also through sonifying the phenomena and creating musical patterns driven by the same equations that dictate the behaviour.
