Hi, There YouTube.
Do you know what this is? This is a Tibetan Singing Bowl.
This one is cast out of bell metal it measures roughly ten centimeters in diameter.
I go this one quite cheaply off amazon. From a company called Silent Mind.
They come in all shapes and sizes. I was in Glastonbury last week and there was a fantastic
shop absolutely full of singing bowls. Small ones to huge crystal ones. It really was quite
an experience. If you are in Glastonbury I'd definitely recommend a visit.
Singing bowls work in the same principle as running a wet finger around the edge of a
wine glass. It comes with a wooden mallet one end is covered in felt. We don't want
to wrack the bowl that would just damage it.
So what you do is gently rotate the felt-covered end around the outside of the bowl. And as
you can hear it's starting to oscillate now this is caused by the metal vibrating and
changing shape rather a lovely sound. Don't you think?
Now the same sound can be produced by reversing it. And if you change direction there's a
very subtle quality on the sound. Singing bowls are used for music, meditation the frequency
they emit is very similar to Gregorian Chanting or even Plainsong. It makes the mind focus
into a meditative state. I have to snap out of it myself.
And there you go. Tibetan Singing Bowls.
I've used the desktop application Audacity to record the sound made by the singing bowl.
As you can see as it begins to osscilate it alternates from peaks and troughs. Quite a
beautiful image. Now let's have a look at the singing bowl
close up.
So now if I slowly start rubbing the stick covered in the felt around the rim. It takes
a while to resonate as you can hear the bowl is starting to oscillate. Vibrations are making
the metal of the bowl change shape produces this rather haunting sound.
Now I've heard that the sound quality can change by adding water this can also produce
a scientific effect called Faraday Waves where the water constrained by the bowl produces
these waves. let's see if I can get that effect going.
Unfortunately, I was unable to generate the effect I wanted. But have a look online there
are some pretty spectacular videos out there.
Thank You for watching I enjoyed making this video and I hope you enjoyed watching it.
Bye!
