Enchanted Waltz in a Grand Conservatory

Create this image of a conservatory inside of a manor: You are enveloped by the music of a harpsichord. To your astonishment, two ghosts are dancing to the music and take no notice of you. The fireplace glows with a ghostly light, and you notice no one sits at the harpsichord—it plays by itself. You hear the whimper of a small animal. Peering under the harpsichord, you notice a dog.
