This research emerges from the encounter between a human and a machine. The oscilloscope was originally designed as a practical tool for various fields of research and industry, with no inherent connection to art. Yet, I am far from the first to be captivated by its potential in the realm of audio-visual expression. Humans have a remarkable tendency to create art from the coldest materials, transforming mere tools into musical instruments or even masterpieces - which I will later discuss. We redefine the function and destiny of objects, opening doors to entirely new dimensions of experience. In the following pages, I invite you to join me on my journey of discovery with the oscilloscope. After the initial amazement and curiosity, I began to ask: How can I incorporate this device into my practice as a composer? Can it serve not only as a tool for composition but also as an instrument in live performance? Is it possible to integrate it with acoustic instruments? And how does it function within an ensemble? These questions demand both theoretical investigation and empirical exploration. They require a deep dive through the membrane separating naive discovery from the expertise that brings creative visions to life. This might sound poetic, but what am I actually talking about?
[What]
An oscilloscope is a type of electronic test instrument used to visualize and analyze the behavior of electrical signals. It generally displays a graph of voltage (vertical axis) against time (horizontal axis), allowing users to observe how signals change over time. This visual representation helps to identify characteristics like signal frequency, amplitude, shape, and irregularities. Oscilloscopes are widely used in the sciences, engineering, biomedical, automotive and the telecommunications industry. For example, they can be employed to troubleshoot circuits, analyze sound waves, or study complex phenomena like vibrations or electromagnetic waves. Modern oscilloscopes often feature digital technology, storing data and offering advanced processing, but traditional analog models are still appreciated for their simplicity and real-time responsiveness. The device typically includes input channels, adjustable time and voltage scales, and various modes to focus on specific parts of a signal. In creative fields, oscilloscopes can be used to turn audio signals into dynamic, real-time visual patterns, offering a bridge between sound and visual art. These patterns often appear as fascinating waveforms or abstract shapes, making the oscilloscope a unique tool for experimental music and multimedia compositions. In essence, the oscilloscope transforms invisible electrical signals into something tangible, making it invaluable for both technical analysis and artistic exploration.
[Why]
Since my initial encounter with the oscilloscope, I have felt a profound and intrinsic connection to it. Over time, I have gradually gained greater clarity about the reasons behind this fascination. My motivation can be organized into a few key concepts, which I will explore in detail throughout this exposition. These concepts will frequently reappear in connection to further investigation. My first, intuitive interest in this subject stems from its aesthetics. I am deeply captivated by the visual and tactile appeal of vintage devices, cathode ray screens, and analog tools. The striking figures that emerge on the oscilloscope’s screen, combined with the direct manipulation of synthesizer knobs to shape sound and image, exemplify a unique one-to-one relationship between auditory and visual elements. This interplay between sound and image also prompts a broader philosophical and spiritual reflection: the multifaceted nature of reality juxtaposed with the inherent limitations of human perception. In this context, the relationship between these two mediums offers a multisensory mode of artistic experience, opening a window into two dimensions that represent the same phenomenon. These interconnected worlds—visual and auditory—are unified by the shared principles of mathematical ratios. The oscilloscope serves as a powerful bridge between these domains, providing a tangible means of exploring their underlying connections and shared structures.
[How]
To answer my research question, I have divided my research in the following parts. First, a dive into the historical and theoretical context; second, my personal contribution. With my background deeply rooted in the jazz tradition, embarking on this journey has required me to step outside my usual practice and explore uncharted territory. To approach this endeavor thoroughly and avoid superficiality, I have delved into the history and theory relate to the oscilloscope, as well as the broader field of visual music. While it is impossible to address every aspect of visual music within the scope of this exposition—given the wealth of existing material on the subject—I find it essential to outline my process of acquiring knowledge and developing an understanding of the field. This foundation will support the practical component of my research, where I will present my approach to the topic through concrete examples, share my contributions, and document my creative process in composing music. The exposition will conclude with an analysis and reflective retrospection on the outcomes of my work. This document is intended primarily for readers who, like myself at the outset, come from a relatively traditional background but are curious about exploring multimedia practices. For readers with more experience in this field, the theoretical portion may be less novel or engaging; they may choose to focus on the practical sections, where my contributions and examples are documented.
