Maybe it's a story where Harry discovers a hidden castle through a magical portal. Inside, he finds powerful magical artifacts and has to protect them from dark wizards.

I'm not sure specifically as I haven't read that exact fanfiction. But generally, it might be about a castle in the Harry Potter universe that doesn't exist in the original books. It could be a place full of mystery, perhaps with its own unique magic, and the fanfiction might explore the adventures of the characters in this never - was castle.
It might be a very creative piece of fanfiction. Since Harry Potter is known for his adventures and the castle (like Hogwarts) is a central place in the series. The 'sings' part could add a unique artistic touch, perhaps Harry is singing spells, or singing about his friends and the challenges he has faced in the castle. It could also be a story where his singing has some sort of magical effect within the castle.
Well, it could be about Harry using his magic in a new and creative way to build a castle. Maybe he's tired of Hogwarts and wants to create his own place. He might use spells like Wingardium Leviosa to lift the stones and Protego to protect the construction site.
