sound surrounds us, but still invisible to the naked eye. But with the right materials and a few acoustic effects, you can bring sound and sight into spectacular patterns. Lord of the Ring: ring of power It was a brilliant title sequence for the prequel series.

According to the creative director’s blog post Anthony VitalianoThe creators of the title credits had ambitious goals. It was to visualize the harmony and conflict of Tolkien’s world based on the immortal beings of Ainur, who “sing beautiful music, and from the sound itself the world is created.”

So they turned to the science of acoustics to create the title sequence “built out of a world of sounds.”but what that is These striking symmetrical patterns ring of powertitle sequences and how did the creators use sound to create them? twitter thread From game designer Alex King on the topic, learn how science helped bring the title sequence of this fantasy series to life with expert help. Let’s dive in.

reel science is reverse A series that reveals the real (and fake) science behind your favorite movies and TV shows.

what pattern do you have ring of power?

the opening credits of ring of power Characterized by the oscillatory motion of fine particles such as stones and grains of sand, they form circles, curves, and even two opposing trees. Lord of the Ring mythology.

According to John McGowan, a lecturer at Edinburgh Napier University who conducts research on interactive sound visualization, these movements could be explained in the title sequence as “Chladni patterns”.

Ernst Chladni, an 18th-century German musician and physicist, experimented with visualizing sound waves in striking patterns. He placed the powder on a metal plate and pulled a violin bow along the edges of the plate’s surface, creating an acoustic vibration that caused the powdered particles to move along the plate, henceforth known as Chladnihis pattern. formed a strange shape that Violin makers still use Chladni’s principles and diagrams to create better sounding violins. Physicists and acoustics experts call these metal plates “Chladni plates”.

“Ernst Cladni was one of many people over the years who experimented with different forms of visualization media to create these patterns,” says McGowan. reverse.

How do you visualize sound?

Chladni may have laid the groundwork, but Swiss scientist Hans Jenny crossed the pond in the 1900s to truly develop the field of cymatics, the scientific field that studies sound visualization. It’s a person.

You can also try making Cymatics patterns at home using a speaker and salt. McGowan says people have also created unusual cymatic patterns from violin and guitar bodies.

“What we’re looking at in cymatics is a visual representation of sound waves in a visualization medium like sand or salt,” says McGowan.

In physics and acoustics, there are properties called “nodes” and “bellies.” When an acoustic vibration is generated at a particular frequency, the particles move away from the sound waves vibrating across the metal plate (antinodes) and cluster in static locations (nodes), forming unique patterns.

Still confused? Ask McGowan to compare the strings of a guitar to sound waves.

If we think of a vibrating guitar string (as a sound analogue), the fixed ends of the string, not moving at the bridge or nut, are the nodes. The vibrating part of the vibrating string is the antinode.

Essentially, these symmetrical patterns are “visual representations of nodes and antinodes vibrating on the surface of the plate,” McGowan adds.

At low frequencies, sound waves have fairly long wavelengths and look like spheres or “sound bubbles”, so the visual lines you see in these patterns do not represent perfect sound waves.

“Think of the visible lines as cross-sections of that sonic bubble. It’s like cutting an orange to see a 2D version of a 3D phenomenon,” says McGowan.

Various patterns can be created by changing the frequency of the vibration sound. Here’s how it works.

Any sound has a fundamental frequency and harmonic frequencies, the latter being multiples of the former. A sound with a fundamental frequency of 100 hertz (100Hz) is followed by harmonic frequencies of 200Hz, 300Hz, and so on.

“So when a tone/note is played on the cladni plate, the action of the violin bow will cause harmonic frequencies to be played on the plate,” explains McGowan.

Harmonic frequencies rearrange the image formed within the particles. This is because the vibrating edges of the plate caused by the violin bow create “higher frequencies with smaller waveforms and more complex symmetries.”

Cymatics experts use audio devices such as tone generators to create specific patterns from sounds. These tone-producing patterns typically take a long time to change from one pattern to the next. “Because the tone needs to reach the next harmonic that matches the size of the plate itself,” he explains McGowan.

“In general, patterns created on square plates are very predictable, but visualizing sound in differently shaped spaces yields different results,” adds McGowan.

How was the pattern for The Rings of Power created?

While not credited, McGowan has expertise in particle animation and has developed audio visualization therapeutic tools for people on the autism spectrum. The edge of the plate is not visible in the title sequence. This is usually seen on his Chladni metal plates which are square. The type and size of plate used also affects the pattern.

“Wavelength and frequency are related, so depending on the size of the plate, only certain frequencies are clearly visualized,” McGowan says.

Since the pattern is partially plate-dependent, we know that a four-sided square plate produces a four-sided symmetrical pattern.

“So the four edges of the plate vibrate to produce a fundamental tone (fundamental frequency),” McGowan says. I will explain.

But if the particles are scattered on top Round Diaphragm, various patterns are formed.

“But if you look at a round plate, the oscillating edges create different patterns because there is one oscillating edge where the pattern created is primarily based on internal reflection and refraction from that circle. ‘ adds McGowan.

In the end it’s likely to be a combination of real cymatics and CGI ring of powertitle credit available. We are well past the time when a cladoni needed a violin bow to create enchanting patterns.

“It appears that the creators used a sequence of filming real vibrating plates of various shapes and then blended their own designs with what was taken from reality to create a CGI-animated version of it,” McGowan said. concludes Mr.
