Pipe Organ
Pneumatic musical instrument, a large keyboard instrument with a long history spread in Europe.
The pipe organ is composed of sound pipes, sound stops, keyboard, rail machine, bellows, and piano box. The sound pipes of the pipe organ are generally whistle pipes and reed pipes with two different pronunciation modes. The whistle pipe is the main body and most of them are made of wood. The sound stop is also called a pull stop, which is a circular protruding button that can be pushed and pushed out. The slide plate is controlled by a rail-rod machine to control the sound tubes; the slide board has holes corresponding to each sound tube in the row. The main types of stops include: main stops, flute stops, string stops, reed stops, change stops, mixed stops, combined key stops, etc. The pipe organ has a loud volume, majestic momentum, beautiful and solemn timbre, and has diverse contrasts, can imitate the effects of orchestral instruments, and can play rich harmonies.
The pipe organ is a type of organ. The difference is that the organ uses a foot-operated blowing device to blow the reeds to vibrate the reeds to produce sounds, while the pipe organ relies on copper or wooden sound pipes to produce sounds. In the early days, playing the organ usually required two people, one to play and one to blow the wind (usually a young boy from a church believer). This method lasted for more than 2,000 years. Later, the scale of the pipe organ became larger and larger, and relying on human power to blow the air was no longer enough, so mechanical equipment began to be used to blow the air. As a result, a more complex mechanical keyboard structure was developed. Because of the huge wind pressure, it was impossible to use pure human power to blow the air. It is no longer possible to hold down the keyboard. Common pipe organs now include mechanical pipe organs, electromechanical pipe organs and electric compressed air pipe organs.
The history of the pipe organ
The pipe organ first appeared around 250 BC. It is the most complex, bulky and expensive musical instrument in the history of musical instruments. It is a majestic, Horrible machine. The organ is a purely religious (Christian) instrument and is usually built at the same time as the church or opera house that houses it - because the structure of the organ is directly attached to the building structure. Therefore, there is no clear specification limit for the pipe organ. The size of the pipe organ is determined based on the size and economic strength of the church or opera house itself. The pipe organ is a free-reed instrument among the reed instruments, and its playing method is similar to other keyboard instruments. The range of the sound is extremely wide. Usually, a keyboard with several layers is used, and there is a pedal keyboard under the feet. The specific pitch is controlled by many notes. The treble part is notated in treble clef, and the bass part is notated in bass clef. , the pedal keyboard part is notated in double bass clef. The pipe organ has a large volume and rich tone, and is especially suitable for playing serious and sacred religious music in a solemn atmosphere. In medieval Europe, almost every small town church had a large or small pipe organ. During every religious festival, melodious music could be heard floating throughout the town. Being able to serve as organist in a famous cathedral is also an honor that musicians are proud of.
A pipe organ installed in a medium-sized church has about 1,200 pipes, 16 stops (different tones), two sets of keyboards and pedals, and it takes two years to make it. Later, during assembly, the sound effects must be adjusted according to the indoor acoustic characteristics of the performance location. The largest pipe organ in the world is currently located in an auditorium in Atlantic City.
The Revolution of the Pipe Organ
In the 20th century, people have been able to make the pipe organ simulate the sound of all musical instruments. By adjusting the sound stops, the pipe organ can realistically imitate various musical instruments, from piano to violin. Despite this, people still admire the Bach-style organ music of the Baroque period.
