4. Rub to Make Them Sing
Rubbing a bowl makes it sing, that is where
they got there name. What actually happens is that one tone is enhanced
and all other tones disappear, creating a pure and penetrating ring.
This does not work well with all bowls, although they still will have a
nice sound effect while the other tones remain more in the background.
The right striker is crucial, it needs to be bare wood and of a smaller
diameter. Softer woods will work, but hardwoods, such as found in
commercially made jazz sticks, are by far the best for rubbing around
the rim of the bowl. Press the stick firmly against the rim of the bowl
to prevent a rattling sound. Think of it as riding a wave as you slowly
drag and press the striker around the bowl in circles. Rubbing will
gradually bring out the singing. Not all bowls lend themselves to
rubbing. The thicker the metal of the bowl, especially the rim, the
nicer the sound. Sometimes a light tap to start the sound, then
commencing with the rubbing, will make it work more easily. Do not
expect to get immediate results. It is a skill that has to be developed.
The right pressure is crucial, and you have to hold the bowl firmly and
control it with your fingers. Usually it can not be done with the bowl
placed on a pillow or holder. With patience and the proper hardwood
stick, rubbing thick middle size and small size bowls produces
penetrating, clear partials as all other tones are subdued or disappear.
In general, rubbing thin bowls will not give nice sounds. I have only
one very large thin bowl that produces a nice low humming sound when
rubbed with a big oak stick.
Where do you find a nice round wooden
stick? It is a question people often ask me. Well, you do not have to
look far, they are all around you, although you probably never thought
of it. I have sticks made from wooden handles of kitchen utensils. I
have one made from the handle of a bathroom plunger. I have a couple of
sticks I found in a surplus store. My favorite striker is one I made
from a small oak tree which I had planted myself in the garden. The wood
needs to be clear and smooth, free of checking and cracks. See what you
can find, and keep an eye out for a good jazz stick
