Welsh singer Margaret Watts Hughes, in the 1880s, invented something like a Chladni pattern generator driven by the human voice.

The Welsh popular singer and philanthropist Margaret (Megan) Watts Hughes (invented) a device almost identical in most respects to the transmitter of Bell's Photophone — one which similarly combined the auditory with optical phenomena. Her "Eidophone", which she had conceived of and produced in order to measure the power of her voice, consisted of a mouthpiece leading to a receiving chamber, over which was stretched a rubber membrane, or diaphragm. Her experiments with this device involved sprinkling a variety of powders onto its surface, then singing into it to see how far these powders would leap. This activity would soon take an unexpected turn...

She also managed to add a sort of time dimension to the acoustic figures:

The plate and disc [i.e. diaphragm] being both coated as before, the plate is laid upon the table, the wet colour side uppermost. The disc is now reversed, set vibrating, and, while vibrating is moved along the surface of the wet plate. As it glides over the moist surface, while a steady note is sustained, it leaves behind it a register of every vibration, recorded with the strictest accuracy.

FAQ: Chladni-like art from the 19th Century

What is Chladni-like art?

Chladni-like art refers to patterns created by vibrating surfaces, typically through the use of a violin bow on metal plates covered with sand or similar materials. When the surface vibrates, it creates nodes where the particles settle, forming intricate and beautiful designs. This phenomenon is named after Ernst Chladni, an 18th-century physicist and musician who is often credited with its discovery.

How did Chladni contribute to this art form?

Ernst Chladni is known for his pioneering work in the study of acoustics and vibration. He developed techniques for visualizing sound waves by placing sand on metal plates and bowing them to create various vibrational patterns. His experiments not only contributed to the understanding of sound but also led to the creation of visually stunning patterns that are now appreciated as art.

What materials were commonly used in 19th-century Chladni-like art?

In the 19th century, artists and scientists typically used metal plates, such as brass or iron, which were coated with fine sand or other granules to create Chladni-like art. The plates were often mounted on a frame, and a violin bow or other vibrating instrument was used to induce the vibrations necessary to form the patterns.

How did Chladni-like art influence other fields?

Chladni-like art has influenced various fields, including music, physics, and visual arts. In music, it provided insights into the relationship between sound and physical forms, leading to advancements in instrument design and acoustics. In visual arts, the patterns inspired artists to explore the intersection of science and aesthetics, leading to movements that embraced the beauty of natural phenomena.

Are there modern applications of Chladni-like art?

Yes, modern applications of Chladni-like art can be found in various fields, including acoustics, engineering, and even medicine. Researchers use similar techniques to study sound wave behavior and material properties. Additionally, artists continue to explore these patterns in contemporary art, often combining technology with traditional methods to create dynamic visual experiences.
