12 Strike the head lightly with the supplied mallet
etc. The standard striking point is shown below.
The standard striking
point lies at distance
B from the kettle
edge, which
corresponds to 1/4 to
1/3 of distance A
(distance between
kettle edge and
center of head).
For note comparison a piano is most suitable.
When the toe of the pedal is depressed, a higher
pitch is obtained.
For details on precise tuning refer to “ADJUST­
ING THE SOUND OF YOUR TIMPANI” on the
following page.
As the head will stretch over time, readjustment should be performed periodi­
cally (starting with step 7).
