What does calliope mean?
A calliope is a musical instrument that generates sound by passing steam or compressed air through an array of large, powerful whistles, operated via a keyboard much like an organ. Developed in the United States during the nineteenth century, it became famous for its deafening volume and its association with Mississippi riverboats and traveling circuses, where its far-carrying notes served as audible advertising for miles around. Because of its raucous, penetrating tone, the word has also come to suggest any loud, brash music. Separately, Calliope is the name of the eldest of the nine Greek Muses, presiding over eloquence and epic poetry; she was traditionally regarded as the inspiration for Homer's epics. The word derives from the Greek meaning 'beautiful-voiced,' which aptly describes both figures despite the instrument's notoriously unmusical blast. Today the term survives chiefly in historical, nautical, and circus contexts.

Etymology of calliope
The word 'calliope' comes from Greek Kalliópē, literally 'beautiful voice,' formed from 'kalos' (beautiful) and 'ops' (voice), the name of the Muse who inspired epic poets. The name was applied to the steam whistle instrument invented in the mid-nineteenth century, presumably ironically or aspirationally given its harsh tone. The same Greek root 'kalos' gives us related English borrowings such as 'calligraphy' (beautiful writing) and 'kaleidoscope' (beautiful form).
How calliope is actually used
The plural 'calliopes' refers both to multiple instruments and, in American English colloquial usage, to small whistles on locomotives. When capitalized, 'Calliope' refers specifically to the Greek Muse.
