「 / 」 solidus

2021 Duration:23 - 26min

A project by dancer / choreographer Ayano Yokoyama and music producer 34423, exploring various relationships between sound and the movement of the body. " / " (Pronunciation: Solidus) is an attempt to recognize individual existence without categorization. Sound is vibration and waves, and waves are also boundaries. We started from the shared concept of expressing the ambiguity, fluctuation, strength, and weakness of the boundaries between all things. In this endeavor, the dancer's movement actively collides with sound as a form of noise cancellation, rather than being synchronized with it. Active noise canceling involves overlaying antiphase sounds to neutralize the sound. However, in reality, the sound doesn't disappear; it persists but in an inaudible state.The 'movement' aiming for a similar effect may become a wall and a boundary without being eroded by sound. In this project, the dancer breaks the boundaries between the visible and the invisible through choreography, engaging the audience's personal imagination and senses. This approach highlights the present moment and individuality.

In this endeavor, the dancer's 'movement' actively collides with sound, serving as a form of noise cancellation. Active noise canceling involves overlaying out-of-phase sounds to neutralize the sound. However, in reality, the sound doesn't disappear; it persists but in an inaudible state. The 'movement' aiming for a similar effect may form a barrier, remaining unaltered by sound. In this project, the dancer transcends the boundaries between the visible and the invisible through choreography, engaging the audience's imagination and senses, emphasizing the present moment and individuality.

- Sound -

We live separated by a single wall. Countless rooms and houses exist as individual territories. While sharing the same time, different moments flow in each room. The flickering of lights in each room contributes to the overall landscape of the city. Within this, there are moments when individual sounds and scents blend together. Waves, a recurring phenomenon within the timeline, involve individual sounds invading their respective territories. Borders are expressed by the degree of noise from the outside perspective.

We are alive, and even as we react to those moments, we continue to live without the ability to completely isolate anything other than ourselves.

Nevertheless, existing without overlap, in parallel.

Contemplating living as individuals and as humans, unbound by categories.
