| Electrical
charges ignite a fuse that fires a lift
charge, which blows the shell out of its
steel, paper, reinforced fiberglass, or HDPE
mortar anchored in the sand. The blast also
lights a time fuse at the shell's base.

Pictured
here the 2.5"-8" shells are fired
from trailers which maybe filled with sand,
which support the 35 pound steel mortars that
hold the shells. This is another favorite
method among pyrotechnicians to fire their
displays. Large trailers are utilized for this
purpose. They can be up to semi-trailer in
lengths.
Another
method is to set-up racks which are made of
wood, sunk metal or HDPE single mortars into
ground. More
often, (the most safest and preferred method)
sand pits or boxes are constructed with
plywood sheets, then mortars are arranged in
order a nd
rest filled in with sand to the top to prevent
any kind of movement. This is a popular method
among pyrotechnicians. Wide variety of sizes
are arranged in firing order, either
e-matched, quick matched or chained with Visco
and other popular methods.
The
shells are then fired using a computer
(usually a laptop) that has been
pre-programmed with a choreographed firing
sequence, and frequently choreographed to
specific music for a particular event. For

fireworks and choreography, click here.

1.
MASTER DIGITAL CONTROLLER
A
portable computer synchronizes music and
fireworks. It picks up a digital firing code
cued from either a simultaneous music
broadcast, CD, or DAT.
2.
THE MORTARS
Mortars
are arranged in wooden racks, sandboxes (or
wooden troughs filled with sand and arranged
together in large groups), or buried in the
ground.
3.
IGNITION
After
the music is cued, a computer signal ignites
the charge that propels the shell into the sky
at 200 mph.
4.
THE 'BREAK"
As
the shell propels into the sky, the fuse burns
into the shell. It explodes the black powder,
which ignites the stars and other components
inside the shell that produce the fireworks
effects -- whistles, streamers, big booms,
brilliant colors and other visual effects.

SECRETS
OF DESIGNING A SHOW
An
explosive medium
While other designer's dreams are brought to
life through paint, textiles, wood and a
myriad of other media, the vision of the pyro-musical
designer is expressed in explosives. For this
unique designer, the sky is their palette,
shells are their media and music, their
inspiration.
The pyromusical designer is a relative
newcomer to the world of fireworks. For
hundreds of years, it was the shell maker who
was the artistic force behind any fireworks
display.
Now, the focus of attention has shifted
towards an overall vision of a fireworks
"show". Synchronization, structure,
coordination and rhythm are the new standards.
The shell maker is still a very important
player in the process, working behind the
scenes to create a repertoire of shells that
explode with precision giving the desired
effect. However, now the shell maker gets
his/her direction from the designer.
Even before the designer begins, a number of
important factors shape the show, including
budget, location, length, weather, safety
issues and specific directions or a
"theme" the client or competition
has put forward. Once these have been
established, the long design process begins.
Selecting
the music
The design process starts with the music. The
designer and his or her team invest a lot of
time listening to music and have usually
developed a bank of music they find inspiring
and conducive to pyrotechnics.
Once the music is selected, a soundtrack is
built. The soundtrack is constructed to
conform with the time duration that has been
set by the client or competition. It is
important the soundtrack not only have a
homogeneity to it, which allows for one
feeling to make a natural transition into
another, but that it also has both high points
and low points, with which to shape the show.
Once the soundtrack is built, the designer
begins to visually create the show. Listening
to the music, they take note of the colors,
forms, shapes and rhythms that come to mind.
These will ultimately express themselves in
the fireworks used.
Then the soundtrack is cut, section by
section. Each section serves as a frame within
which the show is built. Accent points in the
music are targeted, and these become the
points to which the special effects are
synchronized.
In the pyroarchitecture, the designer treats
the water and the skies as vast building
blocks, designing the tables of the show from
the bottom up. Smoke plays an important role
in shaping the design. Since the tables are
created on different levels, something high
and spectacular must be followed by low images
like aquatic shells or a cascading waterfall
to allow the smoke to dissipate.
The designer and team must then cost out the
show to determine whether or not it is within
budget. The designer then returns to his or
her vision and makes any necessary changes.
With all revisions made, the designer
transfers his/her ideas onto paper. The
designer then begins working with a master
shell maker. The designs use both existing
bombs and specially configured bombs created
especially for a specific effect the designer
has in mind.
On average, it takes a show designer about
four to six hours to plan the fireworks
spectacle for each minute of music for a
25-minute show — meticulously synchronizing
the fireworks to cues on the recorded
soundtrack.
FIRING
THE SHOW
Today's fireworks teams use computers to
develop the script, synchronization and timing
of the show, and more and more teams also use
them to fire their shows electrically from the
firing panel. Some teams opt to fire them
individually so as to be able to react
immediately to changing environmental elements
such as humidity (which can make a fuse burn
slightly slower). Other teams have the
computer run the firing of the entire show.

SECRETS
OF DESIGNING A SHOW…PART II
"IN DETAIL"
So
what's involved with producing and planning a
fireworks display?
Much
more is involved than the average spectator
could ever imagine! That’s why we like to
educate people and clients about the lengthy
process of designing a show. Here are the
steps that are taken in order to design a
fireworks performance, which is choreographed
to music. Whether creating a basic fireworks
display or a complex, multi-location
pyromusical, basic steps to achieve the final
result are similar.
Designing
a fireworks display starts when the Special
Projects Manager delivers the initial creative
concept from the client to us. The Display
Designer then designs a show that fulfills the
brief and the client’s expectations.
Together you determine the tone for the
event by discussing the music, emotion, color,
and sound, and how they relate to client’s
theme, if there is one. For example, is
patriotism, humor, mockery or delight needed
in their show? Or does the client wish to
cover a broader range of emotions?
Second
step in the creation of a fireworks display is
selecting a soundtrack. The soundtrack
selection is very important, as it is the
foundation on which a display is designed and
fired. The soundtrack will provide the rhythm
and the tempo of the display and will be a
major influence on what product is picked and
how it is fired.
After
appropriate musical tracks are chosen for the
show (using broadcast-standard editing
software such as Sony
Sound Forge,
Cool
Edit Pro,
CakeWalk,
ProTools
or GoldWave)
the tracks are then digitally edited together.
Individual music selections are combined into
a single music program to create the music
score for the display. Good explosions can’t
overcome bad music. Which is why the songs
chosen are pored over months before the final
track is selected.
Next,
the display designer determines the product
(shells), colors, etc. to integrate into the
music program. A customized shell or database
of product inventory, such as ScriptMaker, is
used and each display item is entered into
this database.
From
there, it is then imported to another
software, (by using easy point-and-click
selection) this time used for choreography.
The designer then listens to every musical
track over and over, while trying to visualize
in his mind a place for each shell or display
item. He listens to any verbal cues in his ear
to match the next lyrics or beat change and
crescendos with the proper fireworks. He then
can create actual scenes in the sky
incorporating varying styles, sound, color and
motion, as each shell or display item is
matched to the mood of the music. This is
where the real artistry and creativity comes
in to play.
Once
the entire product has been scripted into
ScriptMaker we now have to use another
software package, CueMaker. The product from
the choreographed music must be assigned
appropriate display positions. CueMaker
allocates what display positions are going to
be fired from what firing slat or module. If
this is a small display they will all be fired
from one box. However, large displays or
displays involving multiple locations over a
distance require the use of multiple boxes.
This piece of software assigns automatically
all products to a specific cue. This reduces
setup time.
After
this step is completed, yet another software
is used, this time TimeCode Wizard. It creates
time code track to synchronize music to
fireworks. This creates perfect digital time
code for the music score created. The time
code is necessary to synchronize the
choreographed fireworks to the music score.
Time code is recorded on the left channel of a
musical selection, such as CD, or DAT, and the
music is recorded on the right channel.

Once
the show is created, a choreography worksheet
or a script is arranged. A software program
called FireVoice made by FireOne™
System is then utilized. This technology tells
us, and records in synchronization with the
music, exactly when to fire individual cues.
These scripts then go to our storage
containers, where the shells and other display
items are stored. Shells are pulled and cue
numbers are written on each of the shells
matching the firing sequence with the script.
Without it, the fireworks would be a chaotic
mess. The script maps out each second of each
song and the corresponding fireworks that are
supposed to be in the air at that moment. Each
group of fireworks is assigned a number on a
master control board if fired electronically
with a firing panel. Special instructions for
each shot may sometimes appear on product
labels and allocation sheets for the crew
setting up the display to follow.
Designer
then can playback the script with the music to
ensure the timings are exactly on the musical
changes, beats and crescendos. This is as
close to a fireworks rehearsal as it gets
without a shot being fired and from it we can
see the tempo of the display. A database
containing all of the displays product
pre-fire timings operates in the background of
this process and takes care of all the
pre-fire calculations and saves a lot of back
calculating when products are to be fired. The
software does all the work.
The
digital firing of the display is executed by
FireOne™ software in conjunction with
FireOne™ hardware. Additionally, the
software may be used to download the display
into a control panel for firing without a
laptop computer or the software.
Firing system connector rails (also called
slats or firing modules) are set out and
control wires or cables are run. Shells are
then precisely loaded into the mortars and
wires connected to the rails and main modules.
Cables are then extended to the main firing
system. Some firing systems are remotely
controlled, so no cables are necessary.
Once
the checking and re-checking is completed, the
designer then can download the file to the
fire modules or email it to other locations
for downloading, or burn the soundtrack with
time code to a CD, print out the product
stickers and rail allocation reports and give
any final briefings to the crew setting up and
firing the display. Then it is up to the crew
firing the display to make it happen and fire
a perfectly synchronized display to music at
the touch of a button.
Shows
can take anywhere between one to five days to
set up, depending upon size and design
complexity of each show. A small show
can be setup and fired with a crew of 2 to 3
people. Large displays can have as many
as 20 or more pyrotechnicians involved with
preparation and setup.
Setup
details are very important and translate to a
successful show. Some pyrotechnicians may use
a protractor to set specific angles on mortars
to assure correct display patterns in the sky.
Very important when special pattern shells are
utilized, which can only be viewed from a
specific angle. The result of this very time
consuming process can be seen with the show
including Roman Candles and Comets, along with
multiple special shots aerial shells.
Setup
is usually concluded at least 3 or 4 hours
prior to the show. The crew then continues to
check and double-check the site and make final
preparations for the show.
The
final stage is clean up. This is the messiest
and dirtiest part of the entire show.
Debris can be scattered for miles
around the perimeter of the shooting site.
Some people dread the clean-up job. We do not
leave the site until the entire fallout area
has been checked and cleaned of any possibly
unfired material.
So
next time you see a fireworks display, you
will have a better idea how much work and time
goes into creating such a memorable event.
