How the calliope makes its sound
In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the calliope belongs to the flutes (edge-blown): an air jet is split on a sharp edge, setting the air column vibrating – flutes, recorders, whistles and panpipes.
More broadly it is one of the aerophones (wind instruments), where sound comes from vibrating air.
Press play above and watch the spectrum: the evenly spaced peaks are harmonics, and their relative strength is what gives the instrument its character.
From Wikipedia
A calliope (not to be confused with mechanical organs) is an American musical instrument that produces sound by sending a gas, originally steam or, more recently, compressed air, through large whistles—originally locomotive whistles.
A calliope is typically very loud. Even some small calliopes are audible for miles. There is no way to vary tone or volume. Musically, the only expression possible is the pitch, rhythm, and duration of the notes.
