Tuning your Pedal Timpani
Pearl timpani are carefully adjusted with appropriate tuning at the factory, but new heads tend to
stretch during shipment and storage, and would need to be retuned before using. Please follow
the below steps to readjust your instrument.
1. Tuning is adjusted on the lowest note of the timpani.
Fully depress the pedal as shown right.
Standard Tonal Ranges
2. By using the provided tuning key, turn the tuning bolts following the sequence shown below.
At this time, do not fully tighten.
With 88LL(32") and 88L(29"),
turn the tuning bolts in the
sequence as shown.
3. Lightly strike the head with a mallet approximately 5cm
from the edge at each tuning bolt, and find the tuning
bolt with the highest pitch ("Home Tone").
4. When you have found the bolt with the highest pitch,
tighten the other bolts to match the "Home Tone" pitch
in the sequence shown above. Do not strike the heads
too hard, and make sure that you strike lightly so that
you can distinguish the sound of each tuning bolt.
5. When every bolt has been tuned, the lowest note has
been fixed. Next press and depress the pedal a few
times to have the head fix to the kettle. Tighten the bolt
with care when the head stretches during this procedure.
6. After the lowest note has been fixed, press the pedal and
check the highest note. Make adjustments if neccesary.
With 88M(26"),88S(23") and
88SS(20") turn the tuning bolts
in the sequence as shown.

Repeat the above process a few times, and you can tune the timpani from the lowest note to the
highest note by pressing and depressing the pedal smoothly.

Replacing the Head
1. Place your foot on the pedal and loosen the
tuning bolts in the sequence previously
mentioned. Do not turn the bolts at once
and loosen by 1/2 or 1/4 of a turn.
CAUTION
When you loosen the
tuning bolts, the pedal
will suddenly be pulled
down. Place a tennis
ball under the pedal to
prevent injury.

2. When you have all the tension rods
unscrewed, remove the head off with the hoop.
3. Place the new head to
the kettle. Make sure
that the head is in the
center of the kettle.

Tuning Gauge (TG-50)
The Tuning Gauge equipped on the 88 series
timpani shows where to set the pedal for each
note.
The Tone Mark is set depending on the
timapni size and the position can be adjusted
to match the position of the Pointer.
The Pointer is adjusted at the factory. Make
sure that it moves from the highest tone to the
lowest tone, and make adjustments on the
position of the Tone Marks if neccesary.
If the Pointer does not move in the correct
radius, adjust by loosening the Adjustment
Screw with the provided Allen wrench. Make
sure to retighten after adjustment.
If the Pointer moves out of the radius, loosen
the nut on the Link Ball, and move the Tuning
Rod to the right
4.Put the hoop back on and turn the tuning
bolts. Follow the procedures previously
mentioned in "Tuning your Pedal Timpani"
and have your timpani fine-tuned
NOTE
It is recommended that the heads should be
replaced at least once in two years.
The head size should be 2" larger than the
kettle size.
For example, 88M (26") should have 28"
heads

Maintenance
Kettle
The kettle is very fragile. Take extra caution
and prevent any damage or harm to the
kettle.
Use soft cloth to wipe off any dirt. Use extra
care and do not wipe with strength.
Head
After using the instrument, press the pedal so
that the pointer comes to the middle of the
gauge. When you are not using the
instrument for a long time, press the pedal
fully on the heel side to be tuned at the lowest
note.
Make sure to wipe the head after use,
especially where you hands have touched.
Do not forget to place the head protection
cover included to protect the heads.
