Ringing meets Quivering
-on the artistic works of Mr. Taebok Cho and Ms. Jinhee Jung
By Dr. S. Joon Kwon at Korea Institute of Science and Technology (KIST)
Nikola Tesla, a genius scientist from Hungary, once said:
"If you wish understand the universe, think about energy, frequency, and vibration."
In fact, most signals around us are transmitted to our senses through ringing and resonance. From the birth of the universe there have been ringing and resonance, and these two are, in other words, vibrations. The understanding of the object starts with the detection of the signal that the object makes, for example, the music we hear and feel is mediated by the vibration of the air (strictly speaking, the periodic change of density of air in space and time). The visual arts that we see and feel can be said to be signals that mediate the frequency and amplitude of electromagnetic waves (especially visible light for human). Both the periodic fluctuations of air density and the transmission of electromagnetic waves are transmitted to us by a key mechanism of vibration. The fact that music and visual art have in common that they are vibrations, in other words, may mean that a distinct sense of human hearing and vision can be integrated into one sense when focused on the vibrational movement itself. Of course, the vibration of the air and the transmission of the electromagnetic wave are different from each other, so the visual organs such as the cochlea and the visual cell such as the viscera and the retina have evolved separately. Nonetheless, if there are some specific artificial mediators that can lead to the integration of the two senses, the fusion of sound and visual arts with vibration as a common factor may not be impossible.
The joint work of two artists, Ms. Jinhee Jung and Mr. Taebok Cho, focuses right on this part. The visual arts, that are conveyed only by the vibration of the air, expanded to the visual space by the change of the electric signal of the cheek cells in the cochlea, or the visual art, which is conveyed to the electromagnetic wave and transmitted by the electric signal in the retina, is shifted to the musical space. The work expressed in this way leads to the integration of the sense in a new dimension as an independent art in a time and space. The work of two young artists is not limited to simply visualizing music, or creating BGM suitable for visual arts. There are already well-known ways of expressing music through visualizations such as Spectrogram, Chladni or Lissajous patterns. Conversely, how to convert pattern images with specific symmetry and periodicity into music is also well known to community. However, the works of the two artists are not limited to the simple translation of vibrations such as the one-to-one functional correspondence. Their genuine creativity can be said to be the intuitive integration of invisible objects, not mechanical translations of visible objects. Joh and Jung are boldly borrowing the methodology of physics. The two artists inherited the legacy of the German scientist Heinrich Hertz, using algorithms to interpret vibrations and creating their own electronic signals that can be effectively visualized. This leads to a sensory experience and a higher level of quivering beyond the sampling frequency of human vision. To do this, the two artists decomposed the electronic music into a time and frequency dimension and created a specific mathematical kernel that projected it into complicated but beautiful visual images. Through this, the music as a signal in the frequency-time space is effectively translated into a visualized image of a x-y two-dimensional plane space. Notwithstanding the convergence of the two signals is in accordance with precise methodologies based on physics and electronic engineering, it is taken as an artistic experience for the audience by omitting the cognitive process that this is a sort of functional transformation. It is not difficult to guess that there was a creative fusion of artistic sensitivity and engineering knowledge of the two young virtuosos during the design process for the specific mathematical kernel.
The work of Cho and Jung is attributed to the achievement of the Giga Hertz Award 2018 in German. Interestingly, the name of the German physicist Heinrich Hertz, who is also the father of radio engineering, is not an unfamiliar part when considering the work style of the two artists. It is expected that the work of two young artists who are going beyond the traditional way of appreciation of music and expanding its sensory dimension visually and making creative attempts for it will create a lot of vibrations and quivering in the future.
