PENDULAR

Interactive Musical Performance

Collaborative Project

Ableton, Arduino, Max

2021

Pendular is an interactive musical system that explores the physical motion of hanging objects as a method for manipulating synthesized music. Using wind and light, we work in tandem to control the environment in which these objects react. As the objects swing and spin through the air, their movements are interpreted as sonic transformations ranging from calm and predictable to chaotic and random. It is a collaborative project with Elias Jarzombek.

We are naturally drawn to observing movements such as a balloon flying into the sky, or a pendulum swinging in perfect time. These motions give us a glimpse into the infinite interconnected variables that make up our reality. They captivate us in their seeming randomness (when there are too many variables to model) or their predictability (when the system can be accurately represented with mathematical functions). Observing such phenomena provides us with a moment of meditative peace and contemplation, not unlike the feeling you get when listening to music you love. In our interactive musical system Pendular, we draw a connection between these two sensibilities. The work introduces a method of translating the invisible forces around us into the sonic realm, in an effort to inspire imagination and memory through movement and sound.

Our performance with the interface is structured around the delicate power dynamic between human and natural forces. The musical arrangement reflects this relationship in its combination of organic and inorganic sounds: the disc modulates effects on live vocals while the cube affects the timbre of a synthesizer. We begin by establishing the link between motion and sound: we manipulate the two objects in a predictable manner: pushing, rotating, and shining lights on them in dialogue with the music. We speak lyrics inspired by laws of physics such as Newton’s First Law (An object at rest stays at rest and an object in motion stays in motion…) and the Law of Conservation of Energy (The total energy in an isolated system remains constant…).

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
任何物体都要保持匀速直线运动或静止状态,直到外力迫使它改变运动状态为止。

Newton's First Law

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
能量既不会凭空产生,也不会凭空消失,它只会从一种形式转化为另一种形式,或者从一个物体转移到其它物体,而能量的总量保持不变。

Conservation of Energy

As the performance progresses, we relinquish control and allow natural forces to dictate the narrative. We start using a fan to move the objects. As we adjust the source, direction, and strength of the wind, the trajectory of each object becomes increasingly random and unpredictable. We also activate hanging light sources that shine on the objects as they move in the wind. As our voices — each speaking a different language — blend into an abstract soundscape and the synth sound becomes wild and atonal, our performance then becomes more about responding to the motion than triggering it.

 

Through this exchange of roles, Pendular describes not just the natural movement that we see, but also how our mind oscillates between different states, and how the relationships between people, technology, and nature are constantly changing in response to each other.

Pendular

Poem by Zairan Liu

让心脏短暂飞行

在悬浮的海里

命运从我的手里

吃着晚餐的米粒

被黑暗强求

对折呼吸

我的眼睛便急驰向深处

 

夜的边界尚未显现

吊死的鬼不甘寂寞

归来,一种谬误

沿着袅袅的光的残留

追随风的味道

在夜晚里味蕾打开

做梦,像进入女人的身体般

下沉 —— 

在融蜡般的黑海中浸了一夜

却不曾与沉默共生

只剩一颗心脏 即将燃尽 

飞行 在找到落点之前
