The origin of copper, each characteristic, in the role of the symphony BQ

Brass instruments? Brass pipes originated from the horns used in ancient hunting and later developed into different sizes and shapes.

The French horn plays a very important role in the symphony orchestra as it is a melodic instrument with a wide range and a rich and harmonious timbre, which is easy to integrate with other instruments.

The trumpet is often used as a color instrument, and in traditional symphonic compositions, it is not used much, except for cadenzas, because its timbre is too bright and prominent. Wearing a trumpet with a mute, the sound played is very weird, which is commonly used in modern **.

The trombone and tuba are basic bass-type instruments, and the melody is rare, and it is important to enhance the brilliance of the orchestra when playing the whole game.

The predecessors of brass instruments were mostly military horns and horns used in hunting. Brass was used in small quantities in early symphonies. For a long time, only two horns were used in symphony orchestras, sometimes with the addition of a trumpet, and it was not until the first half of the nineteenth century that brass instruments were widely used in symphony orchestras.

Brass instruments are articulated differently from woodwind instruments in that they do not change pitch by shortening the air column inside the tube, but rather by the change in air pressure in the player's lips and the method by which the instrument itself is connected to an "additional tube". All brass instruments are fitted with similarly shaped cylindrical mouthpieces, and the body is in the shape of a long cone. The timbre of brass instruments is characterized by majesty, brilliance and enthusiasm, and although the sound quality is distinctive, the grandeur and wide volume are the common characteristics of the brass group, which is unmatched by other types of instruments.

Brass instruments: trumpet, cornet, trombone, french horn, tuba.

It is mainly obtained by mining copper ore.

Of the copper mined by humans over the past 10,000 years, 80% is still used in some fields today. This makes copper a bright spot and frontier in the research and development of green materials. Xu Hong, CEO of the International Copper Association in Asia Pacific and China, said here on the 22nd that waste can be reduced and valuable resources can be preserved through recycling.

Copper can be 100 ** and will not change its properties in any way. It is not consumed by being "used". Among the metals known to human civilization, copper has the longest history of reuse.

It is estimated that 80% of the copper mined in the last 10,000 years is still used in some areas today. The amount of energy required to obtain copper through circulation** is 75 to 92 less than the energy required to convert copper ore into metal.
