What About Those Buzzers?
The Karimba comes with little brass rings on the lower tines. In
Africa, all traditional karimbas come with some sort of buzzers. If
you've been following the physics Tip of the Day, you know how
amazingly pure the tone of a Hugh Tracey (ie, buzzerless) kalimba can
be, especially after the first 0.1 seconds of the sound has passed and
all the high harmonics have died down. We often find pure tones like
this to be simple or childlike. We also have a desire for interesting
sounds. The buzzers on the kalimbas add high frequency noise and
interest
to the sound.
However, more than half the people I have sold karimbas to don't like
that
buzzing sound. There is more energy in the buzzing than in the
fundamental pitch, so it is sometimes hard to tell what note you played!
Here are some simple things you can do to make a sound that is easier
for you to listen to.
- You can take the buzzers off. Hold the karimba upside down,
with the tines pointing down. Lift a long tine off of the bridge
just enough so the brass buzzer slips past the bridge. Repeat for
all tines with buzzers. Save buzzers for a future time when you
desire a more interesting sound.
- Look at the part of the tine with the buzzer. At the "z-bracket"
and at the bridge the tine vibrations will be at a minimum. However,
in between those two endpoints, the tine vibration will be maximized.
As the tine slides back and forth on that part of the tine, the
buzzing will become louder or softer (like ocean waves, if you can get
the
sliding slow enough). One thing I like to do is to hold the karimba
with its
head tilted slightly down so the buzzers are all away from me, and then
tape
them into place underneath the "z-bracket", so that their buzzing is
minimized.
- Some people are bothered that the upper row of tines does not have
buzzers. One of my Kalimba Magic readers suggested getting staples and
folding them around those upper tines (between the "z-bracket" and the
bridge) so they will have their own buzzers.
We'll have to do an up-coming "Physics of the Kalimba" on the
buzzers sometime soon!
And good news: the Karimba Book went to the printers today!
It is 42 pages, has about 50 exercises, and has about 20
black and white photos to show you things like how to remove
the buzzers. It should be available in 10-14 days. We'll put it
on sale for a week at $15, after which it will be $20, available
only here at Kalimba Magic!
