Great Organ

The "great organ" is a division of a pipe organ that features pipes of the largest scale and loudest tone. It is controlled by a specific manual, or keyboard.1

A pipe organ is a complex musical instrument that produces sound using pipes or reeds, with wind supplied through a mechanism controlled by the organist. These instruments are among the largest, most complicated, and expensive musical instruments, blending sophisticated craftsmanship with artistry. While reed and electronic organs exist, the term "organ" typically refers to pipe organs unless otherwise specified. The organ has a long history and a vast repertoire in Western music.23
