The correct answer is organ. <em>Organ, in music, a keyboard instrument, operated by the player’s hands and feet, in which pressurized air produces notes through a series of pipes organized in scalelike rows. The term organ encompasses reed organs and electronic organs but, unless otherwise specified, is usually understood to refer to pipe organs.</em>
The organ is considered the king of instruments. An organ is a large musical wind instrument having rows of pipes. The pipes of the organ are sounded by compressed air. The pipes are controlled or sounded from a large musical keyboard.
