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 ...
The suona as used in China had a conical wooden body, similar to that of the gyaling horn used by the Tibetan ethnic group, both of which used a metal, usually a tubular brass or copper bocal to which a small double reed was affixed, and possessed a detachable metal bell at its end. The double-reed gave the instrument a sound similar to that of ...
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.
Bell bronze is a two-phase alloy, meaning some of the tin is not dissolved in the copper grains but exists between them. This makes the metal harder and more brittle than a single-phase alloy, and also affects the way the metal responds to hardening by hammering and lathing, and greatly restricts the use of mechanised techniques of manufacture.
[6] [12] [13] They are made of a variety of materials, including fiber, plastic, cardboard, and metal (usually aluminum, brass, or copper). [14] In general, mutes soften the lower frequencies of the sound because they nearly close the bell, but accentuate higher ones due to resonances within the mute.
In the heyday of the music box, some variations were as tall as a grandfather clock and all used interchangeable large disks to play different sets of tunes. These were spring-wound and driven and both had a bell-like sound. The machines were often made in England, Italy, and the US, with additional disks made in Switzerland, Austria, and Prussia.
