[1] Regional names for the rock gong include kungering,[2] kwerent dutse, gwangalan, kungereng, kongworian, and kuge.

[4] Rock gongs have been found in various African locations, such as sites in Burkina Faso, Niger, Nigeria, Sudan,[5] Tanzania in Siuyu and Ughaugha, also in Serengeti (see Itambu, et al. 2018), Uganda, and Zambia.

[6] Rock gongs were brought to the attention of the anthropological community in 1956 by archaeologist Bernard Fagg.

[8] When measured against a tuning fork, a depression on one particular gong was found to have a fundamental frequency of 216 Hz.

[11] Continuous playing of the instrument produces smooth indentations in the rock and a matte-like texture.
