Assembly and Tuning
Before assembling the instrument, please observe the following:
When holding and assembling the instrument, take care not to apply excessive force to the keys.
Applying excessive force may bend the keys, resulting in unbalanced adjustment.
When you assemble the instrument for the fi rst time, you may have diffi culty connecting the joints
due to tightness. In this case, apply a thin coat of the included cork grease to the joint cork, and try
again to connect the joints. If the joints still do not fi t together smoothly, apply a thin coat of cork
grease to the receiver side as well. When applying cork grease, be careful not to apply too much.

Hints on Tuning the Oboe
Th e pitch of an oboe is aff ected by the length and
type of the reed tube, and the length, width, scrape
and gouge of the reed. If you have diffi culty tuning
the oboe, experiment and adjust these elements.
In addition, the temperature in the room and
inside the oboe aff ect the pitch of the instrument.
Before you start to tune, allow the instrument to
adjust to room temperature, or warm the instru-
ment by holding it in your hands.
