How to make a Small brass gong 11:43 Beautiful Sounds Created from Earth, Fire, and Wind! Amazing Korean Ocarina Craftsmen The *kkwaenggwari* originated from the *sora* (small gong)—an instrument used in Goryeo-dynasty court music—and evolved into a leading instrument for *nongak* (farmers' music) and *samulnori* during the Joseon dynasty. Its production begins with the *bangjja* technique, in which copper and tin are melted in a 78:22 ratio to cast a round metal ingot known as *baduk*. This ingot is heated and hammered thousands of times to flatten and shape it into a tray-like form. After rapid cooling to enhance its strength, the instrument is finalized through a "sound-tuning" process, where a master craftsman precisely strikes various points on the resonance surface to calibrate the pitch and refine the metal's acoustic properties. The ocarina originated in 1853 when Giuseppe Donati of Italy adapted an ancient clay whistle into a modern diatonic instrument; its name means "little goose," reflecting its resemblance to a gosling. Production begins by shaping a hollow body from clay that has been processed to remove air bubbles. After precisely carving the mouthpiece—which serves as the air channel—and the sound-splitting edge, the maker calculates the clay's shrinkage rate during firing to drill finger holes and perform an initial tuning. Following shade-drying and high-temperature kiln firing, the instrument is completed by finely grinding the interior of the holes to ensure accurate standard pitch and optimal breath response.
