Tuning problems of Steel Percussion Instrument Tongue Drum
Question 1:what if the instrment out of tune?
First of all,the steel tongue drum is a non-fixed instrument,
it is a normal phenomenon that there is a deviation in the test
range of the sound,generally positive or negative 10 points.
The steel tongue drum can be adjusted by fine-tuning:pitch down by
pressing the tongue for overtone,or by using a file with
grinding(in figure)to file it down at the root of the tongue,
and the tone will be lowered;If it is low tone,please top up
the tongue from its bottom.Generally speaking, our
product sound is a little higher,there is room for fine-tuning.
Question 2:what if the correct method for testing intonation?
Steel tongue drum testing method must be accurate to test the true accuracy.Above all,
the drum is to be flattened.You cannot measure intonation on an uneven surface.
Secondly,to measure the tone of the target tongue,one should press on the other tongues
(figure 1),and then point the target tongue to face the tuner(figure 2).If not,there will
be 1-2 HZ test errors. After knocking on the head position of the tongue several times in a
row while aiming the tuner (Remember, several times of continuous percussion), the
tuner will appear a beating range (the steel tongue drum can only test the sound range
value), which is the intonation of the target test tongue tone.

Instructions for Steel Percussion Instrument Tongue Drum
Please read the following information carefully after receiving the goods:
Step one: To flatten the drum surface after receiving it.
Due to the bumpiness in the way of logistics, your received drum with a curved tongue is
normal and does not affect the pronunciation. You just need to point your thumb at the top
of the tongue and press it down slightly. If you have a concave tongue, open a round black
hole at the bottom and push it slightly with a long stick. This method should be used to
fine-tune in the later period, and will not affect the pronunciation and tone color.
Step two: Avoid severe impact
If the drum appears severe impact deformation,even if it is reset,the tone color of
the tone tongue will be affected because of the change of the resonator cavity.Do
not place heavy objects above the product and avoid severe impact.
Step three: Indoor storage
Drums are made of alloy materials.Please put it in a cool and dry indoor place and
store in room temperature to avoid exposure to the sun and rain.
