5. Pipe organ
Pipe organ is, first of all, one of the most complexly built musical instrument, consisting of many parts, which result in grandiose sound it produces. Main parts of a pipe organ are keyboard(s) and other manual controls, pipes connected to each key on the keyboard, a mechanism that connects them and pumps air into the pipes, and then a device that supplies the air under pressure. There are usually several sets of pipes, which are being controlled by pedals by player’s feet.
