A large Bajoran gong
The Bajoran gong was a small percussive instrument that played a role during Bajoran births.
For Bajoran women, it was important to be relaxed during the birthing process, so the mother's relatives would play different instruments in a repeating rhythm to provide a relaxing atmosphere. During Kirayoshi O'Brien's birth, his father Miles O'Brien played the Bajoran gong; he had trouble keeping up the rhythm, however. (DS9: "The Begotten")
Bajorans also employed large gongs that were used during the Bajoran Gratitude Festival. (DS9: "Fascination")
