Gong

Gong

A gong is an East and South East Asian musical percussion instrument that takes the form of a flat, circular metal disc which is hit with a mallet.
Gongs are broadly of three types. Suspended gongs are more or less flat, circular discs of metal suspended vertically by means of a cord passed through holes near to the top rim. Bossed or nipple gongs have a raised centre boss and are often suspended and played horizontally. Bowl gongs are bowl-shaped, and rest on cushions and belong more to bells than gongs. Gongs are made mainly from bronze or brass but there are many other alloys in use.
Suspended gongs are played with hammers and are of two main types: flat faced discs either with or without a turned edge, and gongs with a raised centre boss. In general, the larger the gong, the larger and softer the hammer. In Western symphonic music the flat faced gongs are generally referred to as tam-tams to distinguish them from their bossed counterparts, although the term "gong" is correct to use for either type. The gong has been an ancient Chinese custom for many eras. They were 1st used to signal peasant workers in from the fields as some gongs are loud enough to be heard from up to 50 miles away. In Japan, they are used to start the beginning of sumo wrestling contests.
Large flat gongs may be 'primed' by lightly hitting them before the main stroke, greatly enhancing the sound and causing the instrument to "speak" sooner, with a shorter delay for the sound to "bloom". Keeping this priming stroke inaudible calls for a great deal of skill. The smallest suspended gongs are played with bamboo sticks, or even western-style drumsticks. Contemporary & avant-garde music, where different sounds are sought, will often use friction mallets, bass bows (producing long tones and high overtones), and various striking implements (wood/plastic/metal) to produce the desired tones.
By far the most familiar to most Westerners is the chau gong or bullseye gong. Large chau gongs, called tam-tams have become part of the symphony orchestra. Sometimes a chau gong is referred to as a Chinese gong, but in fact it is only one of many types of suspended gongs that are associated with China.
The chau gong is made of copper-based alloy, bronze or brass. It is almost flat except for the rim, which is turned up to make a shallow cylinder. On a 10" gong, for example, the rim extends about a half an inch perpendicular to the gong surface. The main surface is slightly concave when viewed from the direction to which the rim is turned. The centre spot and the rim of a chau gong are left coated on both sides with the black copper oxide that forms during the manufacture of the gong, the rest of the gong is polished to remove this coating. Chau gongs range in size from 7" to 80" in diameter.
The earliest Chau gong is from a tomb discovered at the Guixian site in the Guangxi Zhuang Autonomous Region of China. It dates from the early Western Han Dynasty. They were known for their very intense and spiritual drumming in rituals and tribal meetings.
Traditionally, chau gongs were used to clear the way for important officials and processions, much like a police siren today. Sometimes the number of strokes on the gong was used to indicate the seniority of the official. In this way, two officials meeting unexpectedly on the road would know before the meeting which of them should bow down before the other.
A nipple gong has a central raised boss or nipple, often made of a different metal to the rest of the gong. They have a clear resonant tone with less shimmer than other gongs, and two distinct sounds depending on whether they are struck on the boss or next to it. They most often are tuned to various pitches.
Nipple gongs range in size from 6" to 14" or larger. Sets of smaller, tuned nipple gongs can be used to play a tune.

Nipple gongs are used in

Chinese temples for worship.

In Indonesian gamelan ensembles, instruments that are organologically gongs come in various sizes with different functions and different names. For example, in the central Javanese gamelan, the largest gong is called gong ageng, ranges in size up to 1 meter in diameter, has the deepest pitch and is played least often; the next smaller gong is the gong suwukan or siyem, has a slightly higher pitch and replaces the gong ageng in pieces where gong strokes are close together; the kempul is smaller still, has a higher pitch, and is played more frequently. The gong ageng and some gong suwukan have a beat note.
An essential part of the orchestra for Chinese opera is a pair of gongs, the larger with a descending tone, the smaller with a rising tone. The larger gong is used to announce the entrance of major players, of men, and to identify points of drama and consequence. The smaller gong is used to announce the entry of lesser players, of women, and to identify points of humour.
Opera gongs range in size from 7" to 12", with the larger of a pair one or two inches larger than the smaller.
A Pasi gong is a medium-size gong 12" to 15" in size, with a crashing sound. It is used traditionally to announce the start of a performance, play or magic. Construction varies, some having nipples and some not, so this type is named more for its function than for its structure or even its sound.

A tiger gong is a slightly descending or less commonly ascending gong, larger than an opera gong and with a less pronounced pitch shift. Most commonly 15" but available down to 8".

A Shueng Kwong gong is a sharp staccato sound.

Wind gongs are flat bronze discs, with little fundamental pitch, heavy tuned overtones, and long sustain. They are most commonly made of B20 bronze, but can also be made of M63 brass or NS12 nickel-silver. Traditionally, a wind gong is played with a large soft mallet, which gives it a roaring crash to match their namesake. They are lathed on both sides and are medium to large in size, typically 15" to 22" but sizes from 7" to 40" are available. The 22" size is most popular due to its portability and large sound. They are commonly used by drum-kit drummers in rock music.
Played with a nylon tip drumstick they sound rather like the coil chimes in a mantle clock. Some have holes in the centre, but they are mounted like all suspended gongs by other holes near the rim. The smaller sizes have a more bell-like tone due to their thickness and small diameter.
Sculptural gongs are gongs which serve the dual purpose of being a musical instrument and a work of visual art. They are generally not disc shaped, but instead take more complex, even abstract forms. Sculptural gongs were pioneered in the early 1990s by Welsh percussionist and metal crafter, Steve Hubback, who was partially inspired by the work of the French Sound Sculptors, Francois and Bernard Baschet.
Hubback's works have been used by many musicians including solo percussionist Dame Evelyn Glennie and rock drummer Carl Palmer.
English gong and cymbal maker, Matt Nolan, partially inspired by the work of Hubback, also creates Sculptural gongs of his own design or to private commission.
In older Javanese usage and in modern Balinese usage, gong is used to identify an ensemble of instruments. In contemporary central Javanese usage, the term gamelan is preferred and the term gong is reserved for the gong ageng, the largest instrument of the type, or for surrogate instruments such as the gong komodong or gong bumbu which fill the same musical function in ensembles lacking the large gong. In Balinese usage, gong refers to Gamelan Gong Kebyar.
