## Again, pedantic, but the pipes at the end of Reverie sound like a calliope

You’re quite right. You piqued my curiosity on the subject, so I did a little looking around. A pipe organ drives pressurized air through pipes to generate sound, while a calliope drives steam through oversized whistles to produce music. It’s a product of its time (late 19th to early 20th century), when steam power was abundant. Here’s a video of a calliope in action.
