As a concrete example, the idea of a mouse was once counterintuitive to users because they'd never seen one before.

Windows included Solitaire with the OS in part to introduce ideas like "click" or "click and drag" to users that were unfamiliar with GUIs, by linking them to physical concepts users did understand ("oh, I have a physical card, I can grab it and move it around, that makes sense!").

Applies to other things like music too. Sometimes people are ahead of their time and most people can't digest it.
