Lightly strike the head with the mallet about 2
inches (5 cm) from the bearing edge at each
tension rod. Check which tension rod has the
highest sound.
• Pitch of the highest sound is higher than
the tuning note (*)
g Loosen the corresponding tension rod by
about 1/16 to 1/8 of a turn. First loosen
the bolt by twice the desired amount, and
then return (re-tighten) it by half. After
loosening the tension rod, repeat from the

Tighten the other bolts little by little (by about
1/16 to 1/8 of a turn) until the sounds at the
corresponding striking points match the pitch of
the highest sound. Please note that tightening
one bolt also raises the pitch of the neighbor-
ing and opposite tension rods. Thus, after tight-
ening the tension rod with the lowest sound,
again check the pitch at the other tension rods
before tightening the tension rod with the next
lowest pitch. While alternately tightening the
other bolts, do not touch the tension rod with
the highest pitch (reference pitch).
