A 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-inch (25 cm) gong, for example, the rim extends about 1 ⁄ 2 inch (1 cm) perpendicular to the surface. The main surface is slightly concave when viewed from the direction to which the rim is ...
A metallophone is any musical instrument in which the sound-producing body is a piece of metal (other than a metal string), such as tuned metal bars, tubes, rods, bowls, or plates. Most frequently the metal body is struck to produce sound, usually with a mallet, but may also be activated by friction, keyboard action, or other means. [1]
Triangles are made from a variety of metals including aluminum, beryllium copper, brass, bronze, iron, and steel. The metal is bent into a triangular shape with one open end. The instrument is usually held by a loop of some form of thread or wire at the top curve, to enable the triangle to vibrate and it is struck with a metal rod called a ...
Paiban – a clapper made from several flat pieces of wood; also called bǎn (板), tánbǎn (檀板), mùbǎn (木板), or shūbǎn (书板); when used together with a drum the two instruments are referred to collectively as guban Ban; Zhuban (竹板, a clapper made from two pieces of bamboo) Chiban (尺板)
The harmon mute is made of metal (usually aluminum or copper [27]) and consists of a "stem" inserted into a large chamber. [34] The stem can be extended or removed to produce different timbres, and waving one's hand in front of the mute produces a "wah-wah" sound, hence the mute's colloquial name. [34]
In the manufacturing process, the punched metal was curled back onto the underside of the disc, creating a raised projection that resembles a letter A when viewed obliquely. [4] When the Polyphon operates, the resulting disc projections, called plectra , engage with a series of ratchet -like star wheels, each with 9 projections, that sit in a ...
Non-metal mallets are used for general playing, while metal mallets produce a more brilliant sound. Rubber mallets may be used for a warmer sound, although rubber that is too soft may struggle to excite the metal bars. Playing chords on a glockenspiel can be done with four mallets using a grip such as Stevens technique.
The recognized best composition for bell metal though is a ratio of approximately 80 per cent copper and 20 per cent tin. [13] Bell metal of these ratios has been used for more than 3,000 years and is known for its resonance and "attractive sound". [14] Tin and copper are relatively soft metals that will deform on striking.
