The story of the steel drum begins in Trinidad in the 1930s.
0:12
When Street Band skirmishes led to the ban of skin drums. So people in made drums from thick bamboo poles car parts tins and finally oil barrels.
0:22
Up with a whole new sound without skipping a Beat.
0:33
When people first started pounding on steel instruments, they inadvertently dented them. That’s how they discovered that each Dent produced a different pitch.
0:44
Now steel drums are dented on purpose to make a drum head. They cut a piece of Steel into a circle. They weld a metal ring onto it and then they position a metal shell or skirt on the ring and welded in place.
0:58
The drum is held in a big clamp while a worker pinpoints the drumheads exact center.
1:09
He places a measuring guide. They’re using it to Mark radial lines from the center to the rim.
1:20
This line is 10 degrees apart.
1:27
As the drum turns he draw a circular line.
1:29
Make a grid now. He pounds the head of the drum with a Pneumatic Hammer using the grid as a guide to ensure the work is done evenly.
1:41
It takes eight hours of hammering to transform the drum into a bow like shape. This is called sinking the drum then with a special guide for curved surfaces.
1:51
technician measures out another grid inside of the Bold drum head
2:03
He Antoine’s the notes.
2:04
Are about to be hammered out in this case a high B and Annie then he hammers down the steel around each one to shake the note.
2:15
Right takes skill and a lot of time up to 50 hours.
2:23
He trims the drum skirt to the correct length.
2:27
types of stencil of the company logo onto the skirt
2:31
This device is an electrical etching machine.
2:36
Uses acid and electrical current to eat away the steel exposed through the stencil now a technician wields an ultrasonic thickness.
2:54
She presses it against a note using high frequency sound waves the probe measures the steals thickness to within a fraction of a millimeter.
3:05
She grinds down the notes where needed?
3:16
Using a scribing tool. She scratches a line around each note, so it’ll be visible to the player.
3:27
Now it’s time to make sure they struck the right note to tune a steel drum. The technician plays a note with a stick and then dense it with a hammer to adjust the pitch.
3:39
You have to have an ear for this job. He hammers the note until it sounds right. Sometimes he turns the drum upside down to knock out a note from the underside.
3:51
for the fine-tuning, he relies on an electronic tuner a microphone delivers the sound to it and the lines on the screen tell him if the note is in tune or
4:03
Next he burns the border of each note with a blowtorch.
4:21
Then he cools it down with water the process tempers the steel making the notes more resonant. He Tunes the drum again checking for Flaws.
4:32
After the drum is chrome-plated. He Tunes it a final time.
4:43
Taking a hundred and twenty hours to make the steel drum now, it’s time to take a break and party to the steel band sound.
