Editing Calliope (music) (section)

===Pyrophone===
The [[pyrophone]] is a calliope-like instrument that uses internal combustion within its whistles to power their notes, rather than the calliope's system of friction from steam going through ducts.

At 1998's [[Burning Man]], a pyrophone referred to as ''Satan's Calliope'' was powered by ignition of propane inside resonant cavities.<ref>{{cite web|title=Hell's Bells: An engineer's devilish art car produces great balls of fire at Burning Man|author=Sarah Phelan|work= Metroactive|url=http://www.metroactive.com/papers/cruz/08.22.01/burningman-0134.html}}</ref>
