Reeds are used in many wind instruments. Some of the most common are the clarinet, saxophone, oboe, and bassoon. More unusual are instruments that use brass reeds, such as the accordion, and harmonica, not to mention the pipe organ. A lot of the huge pipes have big brass reeds at the bottom of them that sound when the keys are pressed. Similar to this is the bagpipe. It has big wooden or plastic reeds in the bottoms of the large drone pipes. And the chanter pipe that plays the tune has a big loud cane reed made much like a bassoon reed.
