Abstract
A pad for use in a pad cup positioned over an opening in a musical instrument, the pad having a seal element which initially forms an impression of the rim of the opening and fixes the impression. The pad further includes a support member which carries the seal element to securely position the impression relative to the rim to seal the opening when the pad is brought to bear against the rim. The support element also damps vibrations generated when the seal element contacts the rim.
