A sound installation that explores the relationship between two people by connecting the physical act of pulling to music.

As the two participants negotiate their mutual physical equilibrium music responds to the surges in tension, releases, and twists highlighting the nature of their relationship. While the installation affords this personal experience to the participants it also serves as a performance for a larger audience to engage with.

Two wooden handles hang suspended at chest height, connected to each other with a simple band.

We invite participants to explore the subtle musical shifts in tone and harmonic texture throughout the varying positions and tensions afforded by the installation.


In the process of developing this installation, we focused on the idea of finding balance through negotiating physical equilibrium. This handle was to stimulate the tangible interaction of physical forces. The elastic band gives a playfulness of the interactivity, while functions well enough as a medium to convey the pulling forces.

Before playing the instrument, the participants are given simple instruction to slowly pull on the handles. The linearity of both handles is read as a part of the vertical string of the whole installaion. This gives access to the participants to come in and start playing by just grabbing suspended handles. And as the participants explore the tension and the music, the string creates different shapes and scapes around the center of the suspension.


Everything in this world forms its own state of equilibrium. The form is defined by the result of finding a balance of multiple forces surrounding them.

Interactivity happens before the conversation: such ‘feeling’ that instantly happens when they touch or see the object. We wanted to bring that idea into a installation where relationship could be visualized via different medium.

The handle is composed of a load cell, an arduino, a hook, and a LiPo battery, and a switch. The wood is separed into top and bottom parts using tension fit. CNC is used to carve out the wood. The main challenge was to make a design that that could be as ergonomic and light as possible so that it could be hanged using tension of the string.
