The organ is one of the oldest musical instruments in the world. It has a long history of more than 2,000 years and can be seen in large churches. Usually when we watch horror movies, there will be various scary background horror music echoing in our ears from time to time. In the church we could also hear the organ making such horrible noises.

The organ first appeared around 250 BC. It is the most complex, bulky and expensive instrument in the history of musical instruments. This is a majestic and formidable machine.

The pipe 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 pipe organ is directly attached to the building structure. Therefore, there are no clear size limits for organs. The size of the organ is determined by the size and financial strength of the church or opera house itself.

The organ is a free reed instrument among reed instruments, and its playing method is similar to other keyboard instruments. Very wide range of sound. Generally, several layers of keyboards are used, with pedal keyboards under the feet. The specific pitch is controlled by multiple stops. The treble part is recorded in treble clef, the bass part is recorded in bass clef, and the pedal keyboard part is recorded in bass clef.

The organ has a loud and full sound, and is especially suitable for playing serious and sacred religious music in a solemn atmosphere. In medieval Europe, almost every town church had an organ, large or small. Every religious festival, melodious music can be heard everywhere in the town. Being an organist at a famous cathedral is also an honor that musicians can be proud of.

The sound principle of the pipe organ

The organ, like other organs, relies on the compressed air stored in the bellows to control the sound pipe through a complex key mechanism (other organs use reeds) The opening and closing of the lower valve plate controls the pronunciation of the sound tube. The organ is the oldest keyboard instrument, with a history of more than 2,300 years. At first the organ was small enough for the player to play it himself. The Renaissance to Baroque period was the "golden development period" of organ music. Bach, the great father of music, was a very famous organ master (in Bach's time, the piano had not yet been invented).
