The Two Sounds of Your Gong
Yet there are are only two basic sounds the Gong produces: Fundamental Tones and Harmonic Overtones.
The fundamental tone is what we consider to be the voice of the Gong, an almost deep consistent sound that sustains over time. A good way to experience the fundamental sound of the Gong is to strike one (or several times very slowly) slightly below and slightly off-center for a flat gong (as are most European gongs and the Chinese gongs) and on the raised boss, or nipple of an Indonesian gong.
