An "orgue" is a musical instrument that produces sound by forcing air through pipes. It is commonly found in churches, concert halls, and some homes. The instrument can have a wide range of sounds and is played using a keyboard, similar to a piano. Organs can vary in size, from small portable versions to large, complex installations with thousands of pipes. The history of the orgue dates back to ancient times, with early versions like the hydraulis used in Greece. Over the centuries, the instrument evolved, leading to the development of the modern pipe organ, which is known for its rich and powerful sound.
