Revisiting the Tsar Bell

Does a bell have to ring before it is truly a bell? The Russian Tsar Bell is the largest confirmed bell ever cast at over 200 tons. But in 1732, before it was ever struck, this Goliath of bells broke. Its parts have been on display in the Kremlin ever since. A team of UC Berkeley, Stanford, and U Michigan researchers made the Tsar Bell ring for the very first time. With Finite Element Analysis (FEA) and other simulations, the collaborators on the project created a computational model of what it would have sounded like.

On April 15 and 16, the Tsar Bell team presented the project at UC Berkeley’s 2016 Cal Day weekend. A concert performance consisting of June’s Ring by Chris Chafe; The Big Bong by Jeff Davis, and New Forms by DJ Spooky was performed at noon and sunset on Friday, April 15th, and hourly from noon to 4pm on Saturday, April 16th with an additional sunset concert. The collaborators of the project gave a panel discussion at 310 Jacobs Hall on Saturday morning, discussing the project and their individual backgrounds and contributions. Slides depicting an exaggerated simulation of the bell’s distortion pattern at various frequencies was shown.

thumbnailBCNM’s Greg Niemeyer gave a short introduction of the Tsar Bell’s history, including the previous 18,000 kg bell that was destroyed by a fire in the 17th century. The second Tsar Bell, object of the eponymous project, weighed over 200,000 kg and was broken before it ever rang. He also discussed Napoleon’s unsuccessful attempt to remove the Bell and the apocryphal story of Harry Houndini and his wife Bess “ringing” the bell by shooting it from afar. University Carillonist Jeff Davis discussed the uniqueness of the Sather Tower carillon and the minimal metal used in its construction, and Tiffany Ng questioned, “which ‘tsar’ does the Tsar Bell ring for today?”

John Granzow talked about the instrument design and idiophone instruments that vibrate themselves, Chris Chafe presented previous pieces that he wrote for clavichord based upon “ship songs”, while DJ Spooky spoke about Johannes Kepler creating acoustic portraits “of water and ice” and linked bells to drum beats of hiphop with an app he developed. Jeff Lubow linked his previous work with the Natural Frequencies project to the analysis and resynthesis of audio he developed for the Tsar Bell, Perrin Meyer talked about Meyer Sound talked and constructing the subwoofers for the carillon concert.

Richard Straus, who built the keyboard for the University Carillon in 1984, discussed the thousands of “partials” that are created when the bell is struck differently, posing the question that if the small bell contains the big bell, then “what does the big bell contain?” As an alternate creation myth to one of explosions and big bang, he proposed a “harmonic unfolding” of the universe. Olya Dubatova discussed her personal experience of returning to Russia to research the history of Russian bells, interviewing ex-bellringers who were unable to continue their vocation after 90% of the bells were destroyed in the Soviet Union. In relation to a short film of ex-bellringers ringing and hearing the bells for first time in decades, she posed a question: “What does it mean to have a voice?”

The panel presentation was followed by a short Q&A session.

Tsar Bell in the Daily Cal

tsarbell940x400
Amongst all the activities on Cal Day, the Daily Cal featured BCNM’s unveiling of the Tsar Bell, whose electronic replication played in concert with the Campanile in several performances throughout Cal Day. The original bell, damaged in a 1732 fire, remains the heaviest bell ever constructed thought it does not function. On Cal Day, a team of Stanford and Berkeley scientists revealed a simulation of the sound such a bell would make, the culmination of physics, acoustics, engineering, and design research. Reactions on the internet have been swift. From the article:

“According to Niemeyer, Russian citizens remain divided over their perception of the replicated bell sounds — some believe that the researchers “copied” the sound unrightfully. Despite the controversy, Niemeyer maintained that the intent of the project was not malicious, but rather meant to pay homage to the original bell.

“The gesture of American cultural appropriation is dramatic and can be harmful … (but) I feel like for me it’s about pointing back to the origin and honoring the origin in some way,” Niemeyer said.

Does a bell have to ring before it is truly a bell?

 

The Russian Tsar Bell was the largest bell ever cast at over 200 tons. But in 1732, before it was even struck, this Goliath of bells broke. Its parts have been on display in the Kremlin ever since. Now, a team of UC Berkeley and Stanford researchers are making the Tsar Bell ring for the very first time.

 

With Finite Element Analysis (FEA), they created a computational model of what the bell would have sounded like. The recreated Tsar Bell will be “played” in concert with the UC Berkeley Carillon at Sather Tower on Friday, April 15 and Saturday, April 16, 2016 — just in time for Cal Day. The sound will be presented every hour on the hour from noon to 4PM.

Science

Although bronze bells don’t appear to be elastic, when struck, they deform. The deformation moves throughout the bell, and since the bell is round, the deformation circulates until its energy is absorbed by the environment. The sound comes from the deformation moving the air surrounding the bell. The deformations’ constituent frequencies and their amplitudes form waves which define the pitch, volume and timbre of the bell’s sound.

 

Bells don’t whistle, hum, or sing, they ring. The ‘ringing’ is caused by superpositions of the deformation waves. Using Finite Element analysis we can calculate how an object of a certain size and material will deform under a certain impact, and how these deformations will displace air over time. We can also compute the sound of those deformations. To test our approach, we first simulated the sound a known bell and compared its real sound with our simulation.

 

 

ART

Historically, bells represent the collective voices of communities. Perched upon towers, they call people to prayer, warn of danger, and keep time.

 

Today we form communities in many ways, and often they have no geographic center. Like the broken Tsar Bell itself, many cultural experiences are fractured by disruption, migration, and change. Putting the broken fragments of the Tsar Bell back together brings us forward to new and unexpected results, rather than backward to the confines of tradition.

 

In this diverse, fluid cultural landscape the bell’s big public sound invites us to experience our physical communities and seek new meanings together.
