The pipe organ is the King of Instruments that has spanned millennia

Its origins can be traced back to ancient Greece in the 3rd century BCE. Playing a pivotal role in the history of music, the pipe organ is not only widely used in religious ceremonies but also serves as a headline instrument in concerts and performances.

Since the 20th century, while inheriting classical traditions, the pipe organ has continuously integrated modern technology and artistic concepts, showing a trend of diversified development. The core principle of the pipe organ's sound production is "airflow exciting the vibration of pipes"-a mechanism similar to that of brass and woodwind instruments, but with a far more complex structure. Its sound-producing system mainly consists of three parts: the air supply, pipes, and keyboards. The air supply is the "power core" of the pipe organ. Most modern pipe organs use electrically driven blowers to generate stable airflow, which is stored in bellows that regulate air pressure to ensure uniform sound production. When a performer presses a key, the corresponding valve opens, allowing airflow to enter the designated pipe and excite the vibration of the air column inside to produce sound. Renowned as a "mobile building," the pipe organ boasts the most complex structure among all musical instruments. A large-scale pipe organ can consist of tens of thousands or even hundreds of thousands of parts, including the following core components: The pipe array is the most visible structure, usually installed in tall cabinets and arranged by timbre and range. Some large pipe organs have over 10,000 pipes, with the tallest reaching 16 meters, requiring support from the building's structure. The keyboard system includes manual keyboards and a pedalboard. Manual keyboards typically have 2 to 5 rows, each with 88 keys, covering multiple octaves. The pedalboard, used for playing bass parts, has 30 to 40 keys and is controlled by the performer's feet. The pipe organ is also equipped with a sophisticated transmission system connecting the keyboards to the valves, ensuring precise transmission of key presses for an "instant sound response" effect.

Famous for its "majestic, rich, and versatile" timbre, the pipe organ possesses an expansive sound library far surpassing other instruments, earning it the title of "sound palette." More than just a musical instrument, the pipe organ carries profound Western cultural connotations and stands as a dual symbol of religion and art.

The millennial history of the pipe organ is a story of mutual achievement between technological innovation and artistic pursuit. It is not merely an instrument but a "musical monument" transcending time and space, witnessing humanity's ultimate exploration of the art of sound and embodying the eternal pursuit of the sacred and the beautiful.
