Thekong vong toch (Khmer:គងវង់តូច orkong touchKhmer:គងតូច) is a number ofgongs that are attached to a circle-shaped rack, closely resembling its larger relative, thekong thom. Both instruments belong to the percussion family of traditional Khmer instruments, along with theroneat ek,roneat dek, androneat thung. These instruments are all performed in thepinpeat and mahaori orchestras. The kong toch is made of three parts; the frame of the gong circle, the gongs themselves, and the gong mallets.
Thekong toch is analogous to thekhong wong lek used inThai.
TheKhmer wordkorng/ kong "gong" is refers to all types of gong including the flat or bossed gong, single or in a set, suspended on cords from hooks, or a gong placed over a frame. The history of these gongs can be traced in part from the epigraphy and iconography ofFunan-Chenla andAngkor periods, for many can be seen carved on ancient Khmer temple.[1]
Gong Frame
The frame of the gong circle is made from a rattan vine which is smoothed and rounded into shape. Four lengths of the vine are taken to make one frame. The lengths are divided into two pairs, a shorter pair for the inner circle and a longer pair for the outer. The instrument is held up with 16 supports, made of neang nuen, krennoonf, or beng wood. The gong circle is held together with six crossbars, designed to keep the distance between the inner and outer frames fixed. Copper wires are wrapped around the length of each support post, one on the inner and one on the outer.
Gong Heads/Mallets
There are 16 gong heads, which cover a range of pitches. They are rounded and flat in shape with a raised knob in the middle, known as the nipple. The nipple is crucial to the sound, as this is the part being struck by the player. In addition to this, the gongs are tuned by sticking promor (a lead and wax combination) to the underside of the nipple. Two holes are drilled on either side of the gong so it can be suspended in the frame with copper wire. The same gong mallets are used for the kong toch and the kong thom. Themallets have a 25 cm long stick. The heads are made from the earlier mentioned promor, which is then wrapped in four or five layers of cloth and stitched with nylon thread.
Tuning
The kong toch's 16 gong heads are tuned accordingly: (from lowest to highest pitch)·D·Eb·F·G·A·Bb·C·D·E·F·G·A·Bb·C·D
