Stéphane Roy set out to create a contextualized set for Varekai — a design in
which all the elements harmonize with the poetry and language of performance:
costumes, scenery, and music. "In circus, design is essentially the choice of the
spatial context that the director, the other creators and the artists must inhabit.
Whether abstract or realistic, it serves to create a mood." His target with Varekai
was to create a place where magical things could happen. "It was a clearing inside
a forest where people could get together," he says. "A place of refuge, a place of
context." Using Discreet's 3ds Max animation software and Pro/E (industrial
engineering software), Roy and his staff of 12 developed the initial concepts of
a forest set that would both enchant the audience and allow the Cirque performers
to safely execute their moves. And what a fabulous and mysterious hideaway the
VAREKAI characters have made their home in...
Sound design for Varekai was the work of 14-year Cirque veteran Francois Bergeron.
But unlike some of his previous efforts, where sound design was largely an after-the-
fact process, with Varekai Bergeron was on the creative team from the early conceptual
stages. "Because I was involved with the show from the beginning, I was able to fully
integrate the audio elements into the overall concept and into the set," he says. And
that’s a good thing, because according to Bergeron, Varekai features the most complex
audio of any Cirque show he's worked on thus far. "The sound basically reinforces the
set design, with the power emanating from the center above the stage. I think this is
definitely one of the best-sounding Cirque tours yet, and that's in part because I was
able to position the Meyer speakers to maximum advantage."
Daniel Petit, who is in charge of all audio for Cirque du Soleil, was also
instrumental in piecing together Varekai's sound system. Also involved in the audio
component was Varekai director Dominic Champagne. “He loves the audio world, and as
a result, we were able to integrate the systems into the set and help the creative
aspect of the show,” says Bergeron. The result is a wall-to-wall audio experience,
featuring “audio surprises” that far surpass “mere” music and sound effects. “Because
I was playing DJ in the rehearsal, throughout the rehearsal process I played all
sorts of music, sound effects, bits, and samples to stimulate the actors and acrobats
into responding to ambience and feeling,” says Bergeron. “It wasn't just playing a CD.
From there, the composer, Violaine Corradi, was inspired by what was happening on stage
and the reaction of the acrobats to the environment.”
All the action takes place inside the portable 50-meter (165-foot) long tent with
a seating capacity of over 2,600, and this poses quite a unique challenge. According
to Bergeron, the tent's flexible PVC skin, when stretched taut, presents a surprisingly
hard acoustical surface and is highly reflective at problematic frequencies. "It's
really quite reverberant, especially when empty," he says. "For example, at 1 kHz we
measured a reverb time of about 5.4 seconds. So you have to be careful with your
coverage and alignment of speakers."
In an unusual tactic, Bergeron created an inverted sound design, using AutoCAD
design software to make his calculations. “This time, rather than fighting the space
and fighting the canvas, I decided to try to use it,” he explains. “As a result, I
concentrated the sound system from the top, above the ring. Instead of having the
sound system on the ground and using the ground to increase the low end and the sub
bass, here the sub bass is above, which in sound is a kind of no-no. You don't have
any surface to bounce on and increase the level of the low end. But, because we were
so close to the center of the tent, the canvas is so tight that it functions as a
floor, and we used it to that effect.”
Inverting the sound design for Varekai was a first for a Cirque du Soleil show,
and Bergeron relied on self-powered speakers from Meyer Sound Laboratories, Berkeley,
Calif., to achieve the desired result. “One of the benefits with Meyer is that they
do their measurements in an anechoic chamber, which makes their manufacturer specs
very accurate,” says Bergeron. “With the MAPP [testing] software, you can do a lot
of predicting. Based on that, we could easily put the speakers in the set, and know
what we were going to get.”
Other parameters included the fact that with no backstage area, the sound system
had to be integrated into the set. “There's not much leeway,” says Bergeron. “The
selection of the speakers came down mostly to size, power, weight, and of course,
budget.”
Weight was a crucial factor, since the speakers would be mounted on the tent
structure itself, which was also supporting acrobatic rigging and lighting. “There's
no wasted real estate,” adds Bergeron. “It's literally wall-to-wall.”
To supply the needed power from above the stage while avoiding destructive
reflections, Bergeron devised a system comprising three center clusters and an
outer delay ring. The two outside clusters, each with a pair of CQ-1 Wide Coverage
Main loudspeakers, flank the middle cluster of three CQ-2 Narrow Coverage Main
loudspeakers. While these clusters anchor the sound high above the stage,
supplemental reinforcement is supplied by the delay ring of ten UPA-1P Compact
Wide Coverage loudspeakers. Deep bass power, which for both logistical and artistic
reasons also had to come from above, is provided by four PSW-2 High-Power Flyable
subwoofers that are hoisted up in the cupola.All of the speakers are camouflaged
within groupings of the set's pipes.
"We chose the Meyer line of speakers for this show first because of the precise
control," comments Bergeron, "but also because we have been touring for years with
Meyer self-powered speakers and they are very reliable. Having the amplifiers
inside the box eliminates many of the places where things can go wrong in the
audio chain."
Constantly changing temperature and humidity in the big top was another factor
the audio team had to contend with. When the show starts, the doors are opened on
an empty space. Once the tent is filled to capacity, the doors are closed and the
temperature and humidity change significantly.To solve the problem, Pitsch Karrer,
who heads the show's sound department and serves as mixer on Varekai, uses a
temperature probe and hydrometer (humidity gauge) to take a reading of the elements
he's dealing with. And, says Bergeron, Cirque du Soleil has also made strides in
improving temperature control with an HVAC system in the tent. “We're in the
process of cataloguing changes in relationship to temperature and humidity,” he
says. “We'll be able to predict, with a table, before the show what changes need
to be made. Each of those parameters will be stored in the computer, and we'll
be able to recall them at the drop of a hat.”
Bergeron states that the tight confines of the tent were also a point in favor
of the powered systems. "We save space with them. We literally did not have any
backstage space in this show for amplifier racks."
The demands of Varekai quickly put the system to a grueling test. "This is
definitely one of the most audio-oriented shows," says Bergeron, "with wall-to-wall
music and sound effects." Live music comes from a band of six multi-instrumentalists
and two vocalists, with sound effects mixed in from a variety of RAM- and disk-based
digital replay units. In all the production fully occupies the inputs of a 56-input
Soundcraft console plus two Yamaha O1V submixers.
The day-to-day operation of show audio is under the supervision of Pitsch Karrer,
a certified SIM engineer with a background of mixing European tours of Broadway
productions. He works closely with monitor engineers Thomas Duchaine and Stein
Guitton.“Varekai not only has a dense, rich audio track, but it's constantly in
evolution,” says Karrer. “That means I need different sound effects for different
parts of the show. We have to re-program all the sequences at the keyboard. Sometimes
the music doesn't fit the act anymore, so the music is also changed.”
Led by bandleader Michel Cyr, live music comes from a band of six multi-
instrumentalists and two vocalists, with sound effects mixed in from a variety
of RAM-based and disk-based digital replay units, including the Alesis HD24 hard
disk recorder. For mics, the show uses 20 wireless Shure UHF system WL50 and
WL51 units, covering the two singers, four clowns, three Georgian dancers, a
flutist, and a violinist.
The production fully occupies the inputs of a 56-input Soundcraft Series 5
console, plus two Yamaha O1V submixers, all controlled by the LCS LD88 level
control system, which creates “sound images” in the surround.Every microphone
comes into Karrer's sample, which he controls via VCA faders. “Together with the
LCS system, I've created about 70 cues, and each cue mutes or un-mutes a channel,
presets a certain sound effect, which is used for that piece of music,” he
explains.
Bergeron credits the success of the show's sound to the touring crew and strong
support from Daniel Petit at Cirque du Soleil's technical department in Montreal.
"They have been great from the outset," he says. "They took over all the technical
details so I could concentrate on creating the ambience, and on working with the
composer to glue the whole show together with effects and soundscapes. With their
help, I think we've moved to a higher level on sound with Varekai."
