Pipe organ How an organ works A description of the organ
The pipes are made of metal or wood. The metal pipes are round tubes. This alloy makes pipes sound good as the harder tin provides clarity and definition while the softer lead produces tonal warmth. Very small pipes can sometimes be made of silver, like flutes. Some organs also have some pipes made of brass that sound like trumpets. Most organs have a lot of wooden pipes. All the pipes have to be made with an end that tapers at the bottom where the air blows in.
