What is another word for calliophone?
Pronunciation: [kˈalɪˌɒfə͡ʊn] (IPA) 
The term "calliope" is traditionally used to refer to a musical instrument that produces sound by steam whistles. However, there are several other words that can be used to describe similar instruments, including steam organ, steam piano, steam harp, and steam xylophone. Each of these instruments produces sound in a different way, but they all share the same basic principle of using steam or compressed air to create sound. Additionally, the term "calliophone" has also been used to describe a type of telephone that uses steam to transmit sound, although this use of the word is less common today than it was in the past.
