If you do not hear these problems through headphones
Performing at high volume may cause resonant vibration in the
organ itself or in objects near the organ.
Fluorescent lights or glass doors in the room may resonate. In
particular, this is more likely to occur with lower notes at higher
volume.
To reduce such resonances, try the
following steps.
• Move the organ 10–15 cm away from
the wall.
• Reduce the volume.
• Move the organ away from the
resonating objects.
