The Inferno Organ is a traditional dragon instrument(possibly the only one). It consists of a special chamber inside the eerie where long tubes have been hallowed out of the rock. The tubes have holes in them at set distances, and are played like enormous flutes. Each one takes several dragons to operate, one or more blowing fire and several more operating the holes. The dragons also beat rhythmic patterns on special stones used as gigantic drums.
For dragons, music is a communal activity. There are no listeners, everyone participates.
